text: AbstractEngineering projects for complex
technical systems such as automobiles demand extensive requirement specifications
and corresponding hierarchy levels in system architectures. Especially when considering
emergent phenomena, such as total weight or aerodynamics, a closely networked
collaboration of discipline‐specific and cross‐disciplinary roles is required.
Further, in large organizations with a group structure, resulting functional and
non‐functional contents need to be managed by distinct Systems Engineering roles.
For example, the role “property manager” takes care of achieving overarching product
properties, such as weight or aerodynamics, which cannot be directly fixed, but
result from many specifications. This paper proposes new Systems Engineering roles
and their application in a German Original Equipment Manufacturer (OEM). For validation,
the roles have already been applied in everyday engineering projects at the OEM.
The concept proved to be indispensable and transferable to other Systems Engineering
projects.

text: Generating instances of different properties is key to algorithm selection
methods that differentiate between the performance of different solvers for a
given combinatorial optimization problem. A wide range of methods using evolutionary
computation techniques has been introduced in recent years. With this paper, we
contribute to this area of research by providing a new approach based on quality
diversity (QD) that is able to explore the whole feature space. QD algorithms
allow to create solutions of high quality within a given feature space by splitting
it up into boxes and improving solution quality within each box. We use our QD
approach for the generation of TSP instances to visualize and analyze the variety
of instances differentiating various TSP solvers and compare it to instances generated
by established approaches from the literature.

text: 'Classic automated algorithm selection (AS) for (combinatorial) optimization
problems heavily relies on so-called instance features, i.e., numerical characteristics
of the problem at hand ideally extracted with computationally low-demanding routines.
For the traveling salesperson problem (TSP) a plethora of features have been suggested.
Most of these features are, if at all, only normalized imprecisely raising the
issue of feature values being strongly affected by the instance size. Such artifacts
may have detrimental effects on algorithm selection models. We propose a normalization
for two feature groups which stood out in multiple AS studies on the TSP: (a)
features based on a minimum spanning tree (MST) and (b) a k-nearest neighbor graph
(NNG) transformation of the input instance. To this end we theoretically derive
minimum and maximum values for properties of MSTs and k-NNGs of Euclidean graphs.
We analyze the differences in feature space between normalized versions of these
features and their unnormalized counterparts. Our empirical investigations on
various TSP benchmark sets point out that the feature scaling succeeds in eliminating
the effect of the instance size. Eventually, a proof-of-concept AS-study shows
promising results: models trained with normalized features tend to outperform
those trained with the respective vanilla features.'

text: 'To build successful products, the developers have to adapt their product
features and business models to uncertain customer needs. This adaptation is part
of the research discipline of Hypotheses Engineering (HE) where customer needs
can be seen as hypotheses that need to be tested iteratively by conducting experiments
together with the customer. So far, modeling support and associated traceability
of this iterative process are missing. Both, in turn, are important to document
the adaptation to the customer needs and identify experiments that provide most
evidence to the customer needs. To target this issue, we introduce a model-based
HE approach with a twofold contribution: First, we develop a modeling language
that models hypotheses and experiments as interrelated hierarchies together with
a mapping between them. While the hypotheses are labeled with a score level of
their current evidence, the experiments are labeled with a score level of maximum
evidence that can be achieved during conduction. Second, we provide an iterative
process to determine experiments that offer the most evidence improvement to the
modeled hypotheses. We illustrate the usefulness of the approach with an example
of testing the business model of a mobile application.'

text: 'Evolutionary algorithms have successfully been applied to evolve problem
instances that exhibit a significant difference in performance for a given algorithm
or a pair of algorithms inter alia for the Traveling Salesperson Problem (TSP).
Creating a large variety of instances is crucial for successful applications in
the blooming field of algorithm selection. In this paper, we introduce new and
creative mutation operators for evolving instances of the TSP. We show that adopting
those operators in an evolutionary algorithm allows for the generation of benchmark
sets with highly desirable properties: (1) novelty by clear visual distinction
to established benchmark sets in the field, (2) visual and quantitative diversity
in the space of TSP problem characteristics, and (3) significant performance differences
with respect to the restart versions of heuristic state-of-the-art TSP solvers
EAX and LKH. The important aspect of diversity is addressed and achieved solely
by the proposed mutation operators and not enforced by explicit diversity preservation.'

text: 'Previous work by [1] studied gesture-speech interaction in adults. [1] focussed
on temporal and semantic coordination of gesture and speech and found that while
adult speech is mostly coordinated (or redundant) with gestures, semantic coordination
increases the temporal synchrony. These observations do not necessarily hold for
children (in particular with respect to iconic gestures, see [2]), where the speech
and gesture systems are still under development. We studied the semantic and temporal
coordination of speech and gesture in 4-year old children using a corpus of 40
children producing action descriptions in task oriented dialogues. In particular,
we examined what kinds of information are transmitted verbally vs. non-verbally
and how they are related. To account for this, we extended the semantic features
(SFs) developed in [3] for object descriptions in order to include the semantics
of actions. We coded the SFs on the children’s speech and gestures separately
using video data. In our presentation, we will focus on the quantitative distribution
of SFs across gesture and speech. Our results indicate that speech and gestures
of 4-year olds are less integrated than those of the adults, although there is
a large variability among the children. We will discuss the results with respect
to the cognitive processes (e.g., visual memory, language) underlying children’s
abilities at this stage of development. Our work paves the way for the cognitive
architecture of speech-gesture interaction in preschoolers which to our knowledge
is missing so far. '

text: 'Previous work by [1] studied gesture-speech interaction in adults. [1] focussed
on temporal and semantic coordination of gesture and speech and found that while
adult speech is mostly coordinated (or redundant) with gestures, semantic coordination
increases the temporal synchrony. These observations do not necessarily hold for
children (in particular with respect to iconic gestures, see [2]), where the speech
and gesture systems are still under development. We studied the semantic and temporal
coordination of speech and gesture in 4-year old children using a corpus of 40
children producing action descriptions in task oriented dialogues. In particular,
we examined what kinds of information are transmitted verbally vs. non-verbally
and how they are related. To account for this, we extended the semantic features
(SFs) developed in [3] for object descriptions in order to include the semantics
of actions. We coded the SFs on the children’s speech and gestures separately
using video data. In our presentation, we will focus on the quantitative distribution
of SFs across gesture and speech. Our results indicate that speech and gestures
of 4-year olds are less integrated than those of the adults, although there is
a large variability among the children. We will discuss the results with respect
to the cognitive processes (e.g., visual memory, language) underlying children’s
abilities at this stage of development. Our work paves the way for the cognitive
architecture of speech-gesture interaction in preschoolers which to our knowledge
is missing so far. '

text: CAPTCHAs are challenge-response tests that aim at preventing unwanted machines,
including bots, from accessing web services while providing easy access for humans.
Recent advances in artificial-intelligence based attacks show that the level of
security provided by many state-of-the-art text-based CAPTCHAs is declining. At
the same time, techniques for distorting and obscuring the text, which are used
to maintain the level of security, make text-based CAPTCHAs diffcult to solve
for humans, and thereby further degrade usability. The need for developing alternative
types of CAPTCHAs which improve both, the current security and usability levels,
has been emphasized by several researchers. With this study, we contribute to
research through (1) the development of two new face recognition CAPTCHAs (Farett-Gender
and Farett-Gender&Age), (2) the security analysis of both procedures, and (3)
the provision of empirical evidence that one of the suggested CAPTCHAs (Farett-Gender)
is similar to Google's reCAPTCHA and better than KCAPTCHA concerning effectiveness
(error rates), superior to both regarding learnability and satisfaction but not
effciency.

text: 'In this contribution we present a theoretical and experimental investigation
into the effects of reverberation and noise on features in the logarithmic mel
power spectral domain, an intermediate stage in the computation of the mel frequency
cepstral coefficients, prevalent in automatic speech recognition (ASR). Gaining
insight into the complex interaction between clean speech, noise, and noisy reverberant
speech features is essential for any ASR system to be robust against noise and
reverberation present in distant microphone input signals. The findings are gathered
in a probabilistic formulation of an observation model which may be used in model-based
feature compensation schemes. The proposed observation model extends previous
models in three major directions: First, the contribution of additive background
noise to the observation error is explicitly taken into account. Second, an energy
compensation constant is introduced which ensures an unbiased estimate of the
reverberant speech features, and, third, a recursive variant of the observation
model is developed resulting in reduced computational complexity when used in
model-based feature compensation. The experimental section is used to evaluate
the accuracy of the model and to describe how its parameters can be determined
from test data.'

text: Soft-feature based speech recognition, which is an example of uncertainty
decoding, has been proven to be a robust error mitigation method for distributed
speech recognition over wireless channels exhibiting bit errors. In this paper
we extend this concept to packet-oriented transmissions. The a posteriori probability
density function of the lost feature vector, given the closest received neighbours,
is computed. In the experiments, the nearest frame repetition, which is shown
to be equivalent to the MAP estimate, outperforms the MMSE estimate for long bursts.
Taking the variance into account at the speech recognition stage results in superior
performance compared to classical schemes using point estimates. A computationally
and memory efficient implementation of the proposed packet loss compensation scheme
based on table lookup is presented

text: In this paper, we propose an enhanced error concealment strategy at the server
side of a distributed speech recognition (DSR) system, which is fully compatible
with the existing DSR standard. It is based on a Bayesian approach, where the
a posteriori probability density of the error-free feature vector is computed,
given all received feature vectors which are possibly corrupted by transmission
errors. Rather than computing a point estimate, such as the MMSE estimate, and
plugging it into the Bayesian decision rule, we employ uncertainty decoding, which
results in an integration over the uncertainty in the feature domain. In a typical
scenario the communication between the thin client, often a mobile device, and
the recognition server spreads across heterogeneous networks. Both bit errors
on circuit-switched links and lost data packets on IP connections are mitigated
by our approach in a unified manner. The experiments reveal improved robustness
both for small- and large-vocabulary recognition tasks.

text: 'In the direct parameter specification (DPS) mode of sensorimotor control,
response parameters can be specified by stimuli that are not consciously perceived
[Psychological Research/Psychologische Forschung 52 (1990) 207]. DPS is contingent
on the current intentions. The invisible stimuli can be processed for the purposes
of sensorimotor control only if they match the actual intentions, for example,
share task-relevant features. The present experiments explore whether attentional
capture by masked abrupt-onset stimuli is mediated via DPS. Participants judged
which of two visual targets appeared first. Masked primes preceded one of the
targets. The primes were either similar to the targets or not, in shape, or in
color. Target-like (task-relevant), but not distractor-like (task-irrelevant),
primes facilitated perceptual latencies of targets trailing at their positions.
Thus, the latency effects resulted from DPS of an attention shift, rather than
from bottom-up capture or from top-down '

text: Amongst several data driven approaches for designing filters for the time
sequence of spectral parameters, the linear discriminant analysis (LDA) based
method has been proposed for automatic speech recognition. Here we apply LDA-based
filter design to cepstral features, which better match the inherent assumption
of this method that feature vector components are uncorrelated. Extensive recognition
experiments have been conducted both on the standard TIMIT phone recognition task
and on a proprietary 130-words command word task under various adverse environmental
conditions, including reverberant data with real-life room impulse responses and
data processed by acoustic echo cancellation algorithms. Significant error rate
reductions have been achieved when applying the novel long-range feature filters
compared to standard approaches employing cepstral mean normalization and delta
and delta-delta features, in particular when facing acoustic echo cancellation
scenarios and room reverberation. For example, the phone accuracy on reverberated
TIMIT data could be increased from 50.7\% to 56.0\%
