text: "Label noise poses an important challenge in machine learning, especially
in\r\ndeep learning, in which large models with high expressive power dominate
the\r\nfield. Models of that kind are prone to memorizing incorrect labels, thereby\r\nharming
generalization performance. Many methods have been proposed to address\r\nthis
problem, including robust loss functions and more complex label correction\r\napproaches.
Robust loss functions are appealing due to their simplicity, but\r\ntypically
lack flexibility, while label correction usually adds substantial\r\ncomplexity
to the training setup. In this paper, we suggest to address the\r\nshortcomings
of both methodologies by \"ambiguating\" the target information,\r\nadding additional,
complementary candidate labels in case the learner is not\r\nsufficiently convinced
of the observed training label. More precisely, we\r\nleverage the framework of
so-called superset learning to construct set-valued\r\ntargets based on a confidence
threshold, which deliver imprecise yet more\r\nreliable beliefs about the ground-truth,
effectively helping the learner to\r\nsuppress the memorization effect. In an
extensive empirical evaluation, our\r\nmethod demonstrates favorable learning
behavior on synthetic and real-world\r\nnoise, confirming the effectiveness in
detecting and correcting erroneous\r\ntraining labels."

text: Intending to counteract Klein’s second discontinuity in teacher education,
we explored and applied the innovation of “interface ePortfolio” in the context
of a geometry course for preservice teachers (PSTs). The tool offers the possibility
of implementing the design principle of profession orientation. In the article,
we theoretically clarify what we understand by this principle and locate our innovative
concept against this theoretical background. We empirically investigate the extent
to which counteraction against the second discontinuity is successful by analyzing
reflection texts created in the interface ePortfolio, focusing on PSTs’ perspectives.
Our qualitative content analysis shows that most of them perceive the innovation
as helpful in the intended sense and indicates that the course concept, in general,
and the interface ePortfolio, in particular, have helped establish relevant links
between the course content and their later work as teachers.

text: "While FPGA accelerator boards and their respective high-level design
tools are maturing, there is still a lack of multi-FPGA applications, libraries,
and not least, benchmarks and reference implementations towards sustained HPC
usage of these devices. As in the early days of GPUs in HPC, for workloads that
can reasonably be decoupled into loosely coupled working sets, multi-accelerator
support can be achieved by using standard communication interfaces like MPI on
the host side. However, for performance and productivity, some applications can
profit from a tighter coupling of the accelerators. FPGAs offer unique opportunities
here when extending the dataflow characteristics to their communication interfaces.\r\n
\ In this work, we extend the HPCC FPGA benchmark suite by multi-FPGA
support and three missing benchmarks that particularly characterize or stress
inter-device communication: b_eff, PTRANS, and LINPACK. With all benchmarks implemented
for current boards with Intel and Xilinx FPGAs, we established a baseline for
multi-FPGA performance. Additionally, for the communication-centric benchmarks,
we explored the potential of direct FPGA-to-FPGA communication with a circuit-switched
inter-FPGA network that is currently only available for one of the boards. The
evaluation with parallel execution on up to 26 FPGA boards makes use of one of
the largest academic FPGA installations."

text: The non-orthogonal local submatrix method applied to electronic structure–based
molecular dynamics simulations is shown to exceed 1.1 EFLOP/s in FP16/FP32-mixed
floating-point arithmetic when using 4400 NVIDIA A100 GPUs of the Perlmutter system.
This is enabled by a modification of the original method that pushes the sustained
fraction of the peak performance to about 80%. Example calculations are performed
for SARS-CoV-2 spike proteins with up to 83 million atoms.

The article shows how to learn models of dynamical systems
from data which are governed by an unknown variational PDE. Rather
than employing reduction techniques, we learn a discrete field theory
governed by a discrete Lagrangian density Ld that is modelled as a neural network. Careful regularisation of the loss function for training Ld is
necessary to obtain a field theory that is suitable for numerical computations: we derive a regularisation term which optimises the solvability of
the discrete Euler–Lagrange equations. Secondly, we develop a method to
find solutions to machine learned discrete field theories which constitute
travelling waves of the underlying continuous PDE.

text: "The principle of least action is one of the most fundamental physical principle.
It says that among all possible motions connecting two points in a phase space,
the system will exhibit those motions which extremise an action functional. Many
qualitative features of dynamical systems, such as the presence of conservation
laws and energy balance equations, are related to the existence of an action functional.
Incorporating variational structure into learning algorithms for dynamical systems
is, therefore, crucial in order to make sure that the learned model shares important
features with the exact physical system. In this paper we show how to incorporate
variational principles into trajectory predictions of learned dynamical systems.
The novelty of this work is that (1) our technique relies only on discrete position
data of observed trajectories. Velocities or conjugate momenta do not need to
be observed or approximated and no prior knowledge about the form of the variational
principle is assumed. Instead, they are recovered using backward error analysis.
(2) Moreover, our technique compensates discretisation errors when trajectories
are computed from the learned system. This is important when moderate to large
step-sizes are used and high accuracy is required. For this,\r\nwe introduce and
rigorously analyse the concept of inverse modified Lagrangians by developing an
inverse version of variational backward error analysis. (3) Finally, we introduce
a method to perform system identification from position observations only, based
on variational backward error analysis."

text: The numerical solution of an ordinary differential equation can be interpreted
as the exact solution of a nearby modified equation. Investigating the behaviour
of numerical solutions by analysing the modified equation is known as backward
error analysis. If the original and modified equation share structural properties,
then the exact and approximate solution share geometric features such as the existence
of conserved quantities. Conjugate symplectic methods preserve a modified symplectic
form and a modified Hamiltonian when applied to a Hamiltonian system. We show
how a blended version of variational and symplectic techniques can be used to
compute modified symplectic and Hamiltonian structures. In contrast to other approaches,
our backward error analysis method does not rely on an ansatz but computes the
structures systematically, provided that a variational formulation of the method
is known. The technique is illustrated on the example of symmetric linear multistep
methods with matrix coefficients.

description: The numerical solution of an ordinary differential equation can be
interpreted as the exact solution of a nearby modified equation. Investigating
the behaviour of numerical solutions by analysing the modified equation is known
as backward error analysis. If the original and modified equation share structural
properties, then the exact and approximate solution share geometric features such
as the existence of conserved quantities. Conjugate symplectic methods preserve
a modified symplectic form and a modified Hamiltonian when applied to a Hamiltonian
system. We show how a blended version of variational and symplectic techniques
can be used to compute modified symplectic and Hamiltonian structures. In contrast
to other approaches, our backward error analysis method does not rely on an ansatz
but computes the structures systematically, provided that a variational formulation
of the method is known. The technique is illustrated on the example of symmetric
linear multistep methods with matrix coefficients.

text: "Recently, Hamiltonian neural networks (HNN) have been introduced to incorporate
prior physical knowledge when\r\nlearning the dynamical equations of Hamiltonian
systems. Hereby, the symplectic system structure is preserved despite\r\nthe data-driven
modeling approach. However, preserving symmetries requires additional attention.
In this research, we\r\nenhance the HNN with a Lie algebra framework to detect
and embed symmetries in the neural network. This approach\r\nallows to simultaneously
learn the symmetry group action and the total energy of the system. As illustrating
examples,\r\na pendulum on a cart and a two-body problem from astrodynamics are
considered."

Incorporating physical system knowledge into data-driven
system identification has been shown to be beneficial. The
approach presented in this article combines learning of an
energy-conserving model from data with detecting a Lie
group representation of the unknown system symmetry.
The proposed approach can improve the learned model
and reveal underlying symmetry simultaneously.

text: "Ever increasing demands on the performance of microchips are leading to ever
more complex semiconductor technologies with ever shrinking feature sizes. Complex
applications with high demands on safety and reliability, such as autonomous driving,
are simultaneously driving the requirements for test and diagnosis of VLSI circuits.
Throughout the life cycle of a microchip, uncertainties occur that affect its
timing behavior. For example, weak circuit structures, aging effects, or process
variations can lead to a change in the timing behavior of the circuit. While these
uncertainties do not necessarily lead to a change of the functional behavior,
they can lead to a reliability problem.\r\nWith modular and hybrid compaction
two test instruments are presented in this work that can be used for X-tolerant
test response compaction in the built-in Faster-than-At-Speed Test (FAST) which
is used to detect uncertainties in VLSI circuits. One challenge for test response
compaction during FAST is the high and varying X-rate at the outputs of the circuit
under test. By dividing the circuit outputs into test groups and separately compacting
these test groups using stochastic compactors, the modular compaction is able
to handle these high and varying X-rates.\r\nTo deal with uncertainties on logic
interconnects, a method for distinguishing crosstalk and process variation is
presented. In current semiconductor technologies, the number of parasitic coupling
capacitances between logic interconnects is growing. These coupling capacitances
can lead to crosstalk, which causes increased current flow in the logic interconnects,
which in turn can lead to increased electromigration. In the presented method,
delay maps describing the timing behavior of the circuit outputs at different
operating points are used to train artificial neural networks which classify the
tested circuits into fault-free and faulty."

zu Halbleitertechnologien mit immer kleiner werdenden Strukturgrößen. Anwendungen
mit hohen Ansprüchen an Sicherheit und Zuverlässigkeit, wie z.B. das autonome
Fahren, treiben gleichzeitig die Anforderungen an den Test hochintegrierter Schaltungen
an. Während des gesamten Lebenszyklus eines Mikrochips kommt es zu Unsicherheiten
im Zeitverhalten. So können z.B. schwache Schaltungsstrukturen, Alterungseffekte
oder Prozessvariationen zu einer Veränderung des Zeitverhaltens führen. Während
diese Unsicherheiten nicht zu einer Veränderung des funktionalen Verhaltens führen
müssen, können sie jedoch zu einem Zuverlässigkeitsproblem führen.\r\nMit der
modularen und der hybriden Kompaktierung werden in dieser Arbeit zwei Testinstrumente
vorgestellt, die für die X-tolerante Testantwortkompaktierung im eingebauten Hochgeschwindigkeitstest
verwendet werden können. Eine Herausforderung für die Testantwortkompaktierung
während des Hochgeschwindigkeitstests ist die hohe und variierende X-Rate an den
Ausgängen der zu testenden Schaltung. Durch die Einteilung der Schaltungsausgänge
in Prüfgruppen und die separierte Kompaktierung der Prüfgruppen mithilfe von stochastischen
Kompaktierern, können die vorgestellten Verfahren diese hohen und variierenden
X-Raten verarbeiten.\r\nFür den Umgang mit Unsicherheiten auf Verbindungsleitungen
der Logik-Schaltung wird ein Verfahren zur Unterscheidung von Übersprechen und
Prozessvariation vorgestellt. In aktuellen Halbleitertechnologien kommt es vermehrt
zu parasitären Koppelkapazitäten zwischen den Verbindungsleitungen. In dem vorgestellten
Verfahren werden künstliche neuronale Netze trainiert, um die Schaltungen in fehlerfrei

text: "The Koopman operator has become an essential tool for data-driven analysis,
prediction and control of complex systems, the main reason being the enormous
potential of identifying linear function space representations of nonlinear\r\ndynamics
from measurements. Until now, the situation where for large-scale systems, we
(i) only have access to partial observations (i.e., measurements, as is very common
for experimental data) or (ii) deliberately perform coarse\r\ngraining (for efficiency
reasons) has not been treated to its full extent. In this paper, we address the
pitfall associated with this situation, that the classical EDMD algorithm does
not automatically provide a Koopman operator approximation for the underlying
system if we do not carefully select the number of observables. Moreover, we show
that symmetries in the system dynamics can be carried over to the Koopman operator,
which allows us to massively increase the model efficiency. We also briefly draw
a connection to domain decomposition techniques for partial differential equations
and present numerical evidence using the Kuramoto--Sivashinsky equation."

text: "The Koopman operator has become an essential tool for data-driven approximation
of dynamical (control) systems in recent years, e.g., via extended dynamic mode
decomposition. Despite its popularity, convergence results and, in particular,
error bounds are still quite scarce. In this paper, we derive probabilistic bounds
for the approximation error and the prediction error depending on the number of
training data points; for both ordinary and stochastic differential equations.
Moreover, we extend our analysis to nonlinear control-affine systems using either
ergodic trajectories or i.i.d.\r\nsamples. Here, we exploit the linearity of the
Koopman generator to obtain a bilinear system and, thus, circumvent the curse
of dimensionality since we do not autonomize the system by augmenting the state
by the control inputs. To the\r\nbest of our knowledge, this is the first finite-data
error analysis in the stochastic and/or control setting. Finally, we demonstrate
the effectiveness of the proposed approach by comparing it with state-of-the-art
techniques showing its superiority whenever state and control are coupled."

text: "Different conflicting optimization criteria arise naturally in various Deep\r\nLearning
scenarios. These can address different main tasks (i.e., in the\r\nsetting of
Multi-Task Learning), but also main and secondary tasks such as loss\r\nminimization
versus sparsity. The usual approach is a simple weighting of the\r\ncriteria,
which formally only works in the convex setting. In this paper, we\r\npresent
a Multi-Objective Optimization algorithm using a modified Weighted\r\nChebyshev
scalarization for training Deep Neural Networks (DNNs) with respect\r\nto several
tasks. By employing this scalarization technique, the algorithm can\r\nidentify
all optimal solutions of the original problem while reducing its\r\ncomplexity
to a sequence of single-objective problems. The simplified problems\r\nare then
solved using an Augmented Lagrangian method, enabling the use of\r\npopular optimization
techniques such as Adam and Stochastic Gradient Descent,\r\nwhile efficaciously
handling constraints. Our work aims to address the\r\n(economical and also ecological)
sustainability issue of DNN models, with a\r\nparticular focus on Deep Multi-Task
models, which are typically designed with a\r\nvery large number of weights to
perform equally well on multiple tasks. Through\r\nexperiments conducted on two
Machine Learning datasets, we demonstrate the\r\npossibility of adaptively sparsifying
the model during training without\r\nsignificantly impacting its performance,
if we are willing to apply\r\ntask-specific adaptations to the network weights.

text: "In the proposal for our CRC in 2011, we formulated a vision of markets for\r\nIT
services that describes an approach to the provision of such services\r\nthat
was novel at that time and, to a large extent, remains so today:\r\n„Our vision
of on-the-fly computing is that of IT services individually and\r\nautomatically
configured and brought to execution from flexibly combinable\r\nservices traded
on markets. At the same time, we aim at organizing\r\nmarkets whose participants
maintain a lively market of services through\r\nappropriate entrepreneurial actions.“\r\nOver
the last 12 years, we have developed methods and techniques to\r\naddress problems
critical to the convenient, efficient, and secure use of\r\non-the-fly computing.
Among other things, we have made the description\r\nof services more convenient
by allowing natural language input,\r\nincreased the quality of configured services
through (natural language)\r\ninteraction and more efficient configuration processes
and analysis\r\nprocedures, made the quality of (the products of) providers in
the\r\nmarketplace transparent through reputation systems, and increased the\r\nresource
efficiency of execution through reconfigurable heterogeneous\r\ncomputing nodes
and an integrated treatment of service description and\r\nconfiguration. We have
also developed network infrastructures that have\r\na high degree of adaptivity,
scalability, efficiency, and reliability, and\r\nprovide cryptographic guarantees
of anonymity and security for market\r\nparticipants and their products and services.\r\nTo
demonstrate the pervasiveness of the OTF computing approach, we\r\nhave implemented
a proof-of-concept for OTF computing that can run\r\ntypical scenarios of an OTF
market. We illustrated the approach using\r\na cutting-edge application scenario
– automated machine learning (AutoML).\r\nFinally, we have been pushing our work
for the perpetuation of\r\nOn-The-Fly Computing beyond the SFB and sharing the
expertise gained\r\nin the SFB in events with industry partners as well as transfer
projects.\r\nThis work required a broad spectrum of expertise. Computer scientists\r\nand
economists with research interests such as computer networks and\r\ndistributed
algorithms, security and cryptography, software engineering\r\nand verification,
configuration and machine learning, computer engineering\r\nand HPC, microeconomics
and game theory, business informatics\r\nand management have successfully collaborated
here."

text: In this work, the influence of the filler–matrix adhesion on the tensile properties
of laser-sintered parts built with Polyamide 613 filled with glass beads was investigated.
For this purpose, dry blends of glass beads with and without organosilane coupling
agents and polyamide powder were prepared and processed into tensile specimens
on an EOS P396 laser sintering system. The samples were tested both in the dry
state and after an accelerated conditioning in a climate chamber. Furthermore,
finite element method (FEM) simulations were performed to model the extreme cases
of optimum adhesion and no adhesion. By correlating the tensile tests with the
simulation results and by analyzing the fracture surfaces, it was shown that the
filler–matrix adhesion is sufficient in the dry state but is strongly degraded
by conditioning. Even the presence of various organosilane thin films could not
prevent a strong deterioration of the filler–matrix adhesion and the associated
deterioration of the mechanical properties. Since a comparison with an injection-molded
sample of the same polymer filler combination shows identical behavior after conditioning,
it is assumed that this problem is not limited to additively manufactured parts.

text: In the laser sintering technology, the semi-crystalline polymer material is
exposed to elevated temperatures during processing, which leads to serious material
ageing for most materials. This has already been investigated intensively by various
authors. However, the ageing of the material at ambient temperatures during shelf
life has not been the focus so far. The need to analyse the shelf life can be
derived from an ecological and economic point of view. This work is focusing on
the shelf life of PA2200 (PA12). To reduce the potential influences of powder
production fluctuations, two different powder batches stored for 5.5 years and
6.5 years are investigated and compared to a reference powder produced 0.5 years
before these investigations. Multiple powder analyses and part characterisations
have been performed. A significant yellowing and molecular chain length reduction
can be derived from the measurement results. Whereas the influence on mechanical
part performance was minor, the parts built with the stored powders are more yellowish.
As it is most likely that this is due to the consumption of polyamide stabilisers,
it can be assumed that these parts will be subject to significantly faster ageing.
Therefore, it is still not recommended to use the stored powders for critical
parts or light intense and humid environments.

text: Modelling of dynamic systems plays an important role in many engineering disciplines.
Two different approaches are physical modelling and data‐driven modelling, both
of which have their respective advantages and disadvantages. By combining these
two approaches, hybrid models can be created in which the respective disadvantages
are mitigated, with discrepancy models being a particular subclass. Here, the
basic system behaviour is described physically, that is, in the form of differential
equations. Inaccuracies resulting from insufficient modelling or numerics lead
to a discrepancy between the measurements and the model, which can be compensated
by a data‐driven error correction term. Since discrepancy methods still require
a large amount of measurement data, this paper investigates the extent to which
a single discrepancy model can be trained for a physical model with additional
parameter dependencies without the need for retraining. As an example, a damped
electromagnetic oscillating circuit is used. The physical model is realised by
a differential equation describing the electric current, considering only inductance
and capacitance; dissipation due to resistance is neglected. This creates a discrepancy
between measurement and model, which is corrected by a data‐driven model. In the
experiments, the inductance and the capacity are varied. It is found that the
same data‐driven model can only be used if additional parametric dependencies
in the data‐driven term are considered as well.

text: This paper presents a comprehensive study on diagnosing a spacecraft propulsion
system utilizing data provided by the Prognostics and Health Management (PHM)
society, specifically obtained as part of the Asia-Pacific PHM conference’s data
challenge 2023. The objective of the challenge is to identify and diagnose known
faults as well as unknown anomalies in the spacecraft’s propulsion system, which
is critical for ensuring the spacecraft’s proper functionality and safety. To
address this challenge, the proposed method follows a systematic approach of feature
extraction, feature selection, and model development. The models employed in this
study are kMeans clustering and decision trees combined to ensembles, enriched
with expert knowledge. With the method presented, our team was capable of reaching
high accuracy in identifying anomalies as well as diagnosing faults, resulting
in attaining the seventh place with a score of 93.08 %.

The study investigates two different ways of guiding the addressee of
an explanation - an explainee, through action demonstration: contrastive and non-contrastive.
Their effect was tested on attention to specific action elements (goal) as well
as on event memory. In an eye-tracking experiment, participants were shown different
motion videos that were either contrastive or non-contrastive with respect to
the segments of movement presentation. Given that everyday action demonstration
is often multimodal, the stimuli were created with re- spect to their visual and
verbal presentation. For visual presentation, a video combined two movements in
a contrastive (e.g., Up-motion following a Down-motion) or non-contrastive way
(e.g., two Up-motions following each other). For verbal presentation, each video
was combined with a sequence of instruction descriptions in the form of negative
(i.e., contrastive) or assertive (i.e., non-contrastive) guidance. It was found
that a) attention to the event goal increased for this condition in the later
time window, and b) participants’ recall of the event was facilitated when a visually
contrastive motion was combined with a verbal contrast.

text: Coherent nonlinear optical μ-spectroscopy is a frequently used tool in modern
material science as it is sensitive to many different local observables, which
comprise, among others, crystal symmetry and vibrational properties. The richness
in information, however, may come with challenges in data interpretation, as one
has to disentangle the many different effects like multiple reflections, phase
jumps at interfaces, or the influence of the Guoy-phase. In order to facilitate
interpretation, the work presented here proposes an easy-to-use semi-analytical
modeling Ansatz, which bases upon known analytical solutions using Gaussian beams.
Specifically, we apply this Ansatz to compute nonlinear optical responses of (thin
film) optical materials. We try to conserve the meaning of intuitive parameters
like the Gouy-phase and the nonlinear coherent interaction length. In particular,
the concept of coherence length is extended, which is a must when using focal
beams. The model is subsequently applied to exemplary cases of second- and third-harmonic
generation. We observe a very good agreement with experimental data, and furthermore,
despite the constraints and limits of the analytical Ansatz, our model performs
similarly well as when using more rigorous simulations. However, it outperforms
the latter in terms of computational power, requiring more than three orders less
computational time and less performant computer systems.

text: 'Paying taxes is a field of economic activity that has always been highly
morally charged: the question of who pays how much or can avoid or evade the prescribed
payments is always closely related to debate about a fair societal distribution
of burdens. In the process of moralisation, therefore, faith communities such
as the Catholic Church also repeatedly seized the floor to propagate certain norms.
The article examines the contributions of theologians from Spain, the USA and
West Germany in the 1940s and 1950s. It concludes that the norms of taxation they
propagated differed greatly depending on the institutional and economic frameworks
within which they operated. The analysis proves taxation to be a field of economic
action and societal dispute where economics and morality are indissolubly interconnected.'

text: Explanation has been identified as an important capability for AI-based systems,
but research on systematic strategies for achieving understanding in interaction
with such systems is still sparse. Negation is a linguistic strategy that is often
used in explanations. It creates a contrast space between the affirmed and the
negated item that enriches explaining processes with additional contextual information.
While negation in human speech has been shown to lead to higher processing costs
and worse task performance in terms of recall or action execution when used in
isolation, it can decrease processing costs when used in context. So far, it has
not been considered as a guiding strategy for explanations in human-robot interaction.
We conducted an empirical study to investigate the use of negation as a guiding
strategy in explanatory human-robot dialogue, in which a virtual robot explains
tasks and possible actions to a human explainee to solve them in terms of gestures
on a touchscreen. Our results show that negation vs. affirmation 1) increases
processing costs measured as reaction time and 2) increases several aspects of
task performance. While there was no significant effect of negation on the number
of initially correctly executed gestures, we found a significantly lower number
of attempts—measured as breaks in the finger movement data before the correct
gesture was carried out—when being instructed through a negation. We further found
that the gestures significantly resembled the presented prototype gesture more
following an instruction with a negation as opposed to an affirmation. Also, the
participants rated the benefit of contrastive vs. affirmative explanations significantly
higher. Repeating the instructions decreased the effects of negation, yielding
similar processing costs and task performance measures for negation and affirmation
after several iterations. We discuss our results with respect to possible effects
of negation on linguistic processing of explanations and limitations of our study.

text: "Polymer composites represent the industry standard in injection molding for
the production \r\nof plastic components with increased requirements in terms
of heat resistance and stiffness. In the \r\nfield of laser sintering (LS), these
materials are less common so far. In order to extend the available \r\nmaterial
variety for the LS process, new ceramic-filled Polyamide 613 powders are investigated\r\nwithin
the scope of this work. Here, the resulting properties from two different powder
production \r\nmethods are compared. One filled powder is produced by dry blending
and the other powder with \r\nthe same filler and filling ratio is produced by
encapsulating the filler particles inside the polymer \r\nparticles within the
dissolution-precipitation process. It was found that encapsulating the filler
\r\nparticles can provide certain benefits for the processability, for example
an improved powder \r\nflowability or better filler dispersion. However, encapsulating
the filler also alters the thermal \r\nproperties of the precipitated powder."
