text: Management of complex network services requires flexible and efficient service
provisioning as well as optimized handling of continuous changes in the workload
of the service.To adapt to changes in the demand, service components need to be
replicated (scaling) and allocated to physical resources (placement) dynamically.
In this paper, we propose a fullyautomated approach to the joint optimization
problem of scaling and placement, enabling quick reaction to changes. We formalize
the problem, analyze its complexity, and develop two algorithms to solve it. Extensive
empirical results show the applicability andeffectiveness of the proposed approach.

text: In this article we develop a gradient-based algorithm for the solution of
multiobjective optimization problems with uncertainties. To this end, an additional
condition is derived for the descent direction in order to account for inaccuracies
in the gradients and then incorporated into a subdivision algorithm for the computation
of global solutions to multiobjective optimization problems. Convergence to a
superset of the Pareto set is proved and an upper bound for the maximal distance
to the set of substationary points is given. Besides the applicability to problems
with uncertainties, the algorithm is developed with the intention to use it in
combination with model order reduction techniques in order to efficiently solve
PDE-constrained multiobjective optimization problems.

text: 'In order to improve the credibility of modern simulation tools, uncertainties
of different kinds have to be considered. This work is focused on epistemic uncertainties
in the framework of continuum mechanics, which are taken into account by fuzzy
analysis. The underlying min-max optimization problem of the extension principle
is approximated by α-discretization, resulting in a separation of minimum and
maximum problems. To become more universal, so-called quantities of interest are
employed, which allow a general formulation for the target problem of interest.
In this way, the relation to parameter identification problems based on least-squares
functions is highlighted. The solutions of the related optimization problems with
simple constraints are obtained with a gradient-based scheme, which is derived
from a sensitvity analysis for the target problem by means of a variational formulation.
Two numerical examples for the fuzzy analysis of material parameters are concerned
with a necking problem at large strain elastoplasticity and a perforated strip
at large strain hyperelasticity to demonstrate the versatility of the proposed
variational formulation. '

text: State-of-the-art mechatronic systems offer inherent intelligence that enables
them to autonomously adapt their behavior to current environmental conditions
and to their own system state. This autonomous behavior adaptation is made possible
by software in combination with complex sensor and actuator systems and by sophisticated
information processing, all of which make these systems increasingly complex.
This increasing complexity makes the design process a challenging task and brings
new complex possibilities for operation and maintenance. However, with the risk
of increased system complexity also comes the chance to adapt system behavior
based on current reliability, which in turn increases reliability. The development
of such an adaption strategy requires appropriate methods to evaluate reliability
based on currently selected system behavior. A common approach to implement such
adaptivity is to base system behavior on different working points that are obtained
using multiobjective optimization. During operation, selection among these allows
a changed operating strategy. To allow for multiobjective optimization, an accurate
system model including system reliability is required. This model is repeatedly
evaluated by the optimization algorithm. At present, modeling of system reliability
and synchronization of the models of behavior and reliability is a laborious manual
task and thus very error-prone. Since system behavior is crucial for system reliability,
an integrated model is introduced that integrates system behavior and system reliability.
The proposed approach is used to formulate reliability-related objective functions
for a clutch test rig that are used to compute feasible working points using multiobjective
optimization.

text: Heterogeneous compute nodes in form of CPUs with attached GPU and FPGA accelerators
have strongly gained interested in the last years. Applications differ in their
execution characteristics and can therefore benefit from such heterogeneous resources
in terms of performance or energy consumption. While performance optimization
has been the only goal for a long time, nowadays research is more and more focusing
on techniques to minimize energy consumption due to rising electricity costs.This
paper presents reMinMin, a novel static list scheduling approach for optimizing
the total energy consumption for a set of tasks executed on a heterogeneous compute
node. reMinMin bases on a new energy model that differentiates between static
and dynamic energy components and covers effects of accelerator tasks on the host
CPU. The required energy values are retrieved by measurements on the real computing
system. In order to evaluate reMinMin, we compare it with two reference implementations
on three task sets with different degrees of heterogeneity. In our experiments,
MinMin is consistently better than a scheduler optimizing for dynamic energy only,
which requires up to 19.43% more energy, and very close to optimal schedules.

text: "Multiobjective optimization plays an increasingly important role in modern
applications, where several criteria are often of equal importance. The task in
multiobjective optimization and multiobjective optimal control is therefore to
compute\r\nthe set of optimal compromises (the Pareto set) between the conflicting
objectives.\r\n\r\nSince – in contrast to the solution of a single objective optimization
problem – the\r\nPareto set generally consists of an infinite number of solutions,
the computational\r\neffort can quickly become challenging. This is even more
the case when many problems have to be solved, when the number of objectives is
high, or when the objectives\r\nare costly to evaluate. Consequently, this thesis
is devoted to the identification and\r\nexploitation of structure both in the
Pareto set and the dynamics of the underlying\r\nmodel as well as to the development
of efficient algorithms for solving problems with\r\nadditional parameters, with
a high number of objectives or with PDE-constraints.\r\nThese three challenges
are addressed in three respective parts.\r\n\r\nIn the first part, predictor-corrector
methods are extended to entire Pareto sets.\r\nWhen certain smoothness assumptions
are satisfied, then the set of parameter dependent Pareto sets possesses additional
structure, i.e. it is a manifold. The tangent\r\nspace can be approximated numerically
which yields a direction for the predictor\r\nstep. In the corrector step, the
predicted set converges to the Pareto set at a new\r\nparameter value. The resulting
algorithm is applied to an example from autonomous\r\ndriving.\r\n\r\nIn the second
part, the hierarchical structure of Pareto sets is investigated. When\r\nconsidering
a subset of the objectives, the resulting solution is a subset of the Pareto\r\nset
of the original problem. Under additional smoothness assumptions, the respective
subsets are located on the boundary of the Pareto set of the full problem. This\r\nway,
the “skeleton” of a Pareto set can be computed and due to the exponential\r\nincrease
in computing time with the number of objectives, the computations of\r\nthese
subsets are significantly faster which is demonstrated using an example from\r\nindustrial
laundries.\r\n\r\nIn the third part, PDE-constrained multiobjective optimal control
problems are\r\naddressed by reduced order modeling methods. Reduced order models
exploit the\r\nstructure in the system dynamics, for example by describing the
dynamics of only the\r\nmost energetic modes. The model reduction introduces an
error in both the function values and their gradients, which has to be taken into
account in the development of\r\nalgorithms. Both scalarization and set-oriented
approaches are coupled with reduced\r\norder modeling. Convergence results are
presented and the numerical benefit is\r\ninvestigated. The algorithms are applied
to semi-linear heat flow problems as well\r\nas to the Navier-Stokes equations.\r\n"

text: This report describes the computation of gradients by algorithmic differentiation
for statistically optimum beamforming operations. Especially the derivation of
complex-valued functions is a key component of this approach. Therefore the real-valued
algorithmic differentiation is extended via the complex-valued chain rule. In
addition to the basic mathematic operations the derivative of the eigenvalue problem
with complex-valued eigenvectors is one of the key results of this report. The
potential of this approach is shown with experimental results on the CHiME-3 challenge
database. There, the beamforming task is used as a front-end for an ASR system.
With the developed derivatives a joint optimization of a speech enhancement and
speech recognition system w.r.t. the recognition optimization criterion is possible.

text: In this paper we show how a neural network for spectral mask estimation for
an acoustic beamformer can be optimized by algorithmic differentiation. Using
the beamformer output SNR as the objective function to maximize, the gradient
is propagated through the beamformer all the way to the neural network which provides
the clean speech and noise masks from which the beamformer coefficients are estimated
by eigenvalue decomposition. A key theoretical result is the derivative of an
eigenvalue problem involving complex-valued eigenvectors. Experimental results
on the CHiME-3 challenge database demonstrate the effectiveness of the approach.
The tools developed in this paper are a key component for an end-to-end optimization
of speech enhancement and speech recognition.

text: These days, there is a strong rise in the needs for machine learning applications,
requiring an automation of machine learning engineering which is referred to as
AutoML. In AutoML the selection, composition and parametrization of machine learning
algorithms is automated and tailored to a specific problem, resulting in a machine
learning pipeline. Current approaches reduce the AutoML problem to optimization
of hyperparameters. Based on recursive task networks, in this paper we present
one approach from the field of automated planning and one evolutionary optimization
approach. Instead of simply parametrizing a given pipeline, this allows for structure
optimization of machine learning pipelines, as well. We evaluate the two approaches
in an extensive evaluation, finding both approaches to have their strengths in
different areas. Moreover, the two approaches outperform the state-of-the-art
tool Auto-WEKA in many settings.
