text: 'We present an unsupervised training approach for a neural network-based mask
estimator in an acoustic beamforming application. The network is trained to maximize
a likelihood criterion derived from a spatial mixture model of the observations.
It is trained from scratch without requiring any parallel data consisting of degraded
input and clean training targets. Thus, training can be carried out on real recordings
of noisy speech rather than simulated ones. In contrast to previous work on unsupervised
training of neural mask estimators, our approach avoids the need for a possibly
pre-trained teacher model entirely. We demonstrate the effectiveness of our approach
by speech recognition experiments on two different datasets: one mainly deteriorated
by noise (CHiME 4) and one by reverberation (REVERB). The results show that the
performance of the proposed system is on par with a supervised system using oracle
target masks for training and with a system trained using a model-based teacher.'

text: Die Komplexität von Steuersystemen gewinnt in der Debatte um den internationalen
Steuerwettbewerb zunehmend an Bedeutung. Im vorliegenden Beitrag erfolgt, basierend
auf den Daten, die dem Tax Complexity Index (www.taxcomplexity.org) zugrunde liegen,
eine umfassende Gegenüberstellung der Komplexität der Steuersysteme von Deutschland
und Öster-reich unter Berücksichtigung der Mittelwerte aller Länder. Die Steuergesetze
weisen sowohl in Deutschland als auch in Österreich einen verhältnismäßig hohen
Grad an Komplexität auf. Bei den steuerlichen Rahmenbedingungen fällt der Grad
an Komplexität in beiden Ländern dagegen niedrig aus, wobei Österreich im Durchschnitt
weniger komplex ist als Deutschland.

text: We propose a training scheme to train neural network-based source separation
algorithms from scratch when parallel clean data is unavailable. In particular,
we demonstrate that an unsupervised spatial clustering algorithm is sufficient
to guide the training of a deep clustering system. We argue that previous work
on deep clustering requires strong supervision and elaborate on why this is a
limitation. We demonstrate that (a) the single-channel deep clustering system
trained according to the proposed scheme alone is able to achieve a similar performance
as the multi-channel teacher in terms of word error rates and (b) initializing
the spatial clustering approach with the deep clustering result yields a relative
word error rate reduction of 26% over the unsupervised teacher.

text: Signal dereverberation using the Weighted Prediction Error (WPE) method has
been proven to be an effective means to raise the accuracy of far-field speech
recognition. First proposed as an iterative algorithm, follow-up works have reformulated
it as a recursive least squares algorithm and therefore enabled its use in online
applications. For this algorithm, the estimation of the power spectral density
(PSD) of the anechoic signal plays an important role and strongly influences its
performance. Recently, we showed that using a neural network PSD estimator leads
to improved performance for online automatic speech recognition. This, however,
comes at a price. To train the network, we require parallel data, i.e., utterances
simultaneously available in clean and reverberated form. Here we propose to overcome
this limitation by training the network jointly with the acoustic model of the
speech recognizer. To be specific, the gradients computed from the cross-entropy
loss between the target senone sequence and the acoustic model network output
is backpropagated through the complex-valued dereverberation filter estimation
to the neural network for PSD estimation. Evaluation on two databases demonstrates
improved performance for on-line processing scenarios while imposing fewer requirements
on the available training data and thus widening the range of applications.

text: In this paper, we present libDirectional, a MATLAB library for directional
statistics and directional estimation. It supports a variety of commonly used
distributions on the unit circle, such as the von Mises, wrapped normal, and wrapped
Cauchy distributions. Furthermore, various distributions on higher-dimensional
manifolds such as the unit hypersphere and the hypertorus are available. Based
on these distributions, several recursive filtering algorithms in libDirectional
allow estimation on these manifolds. The functionality is implemented in a clear,
well-documented, and object-oriented structure that is both easy to use and easy
to extend.

text: By distributing the computational load over the nodes of a Wireless Acoustic
Sensor Network (WASN), the real-time capability of the TRINICON (TRIple-N-Independent
component analysis for CONvolutive mixtures) framework for Blind Source Separation
(BSS) can be ensured, even if the individual network nodes are not powerful enough
to run TRINICON in real-time by themselves. To optimally utilize the limited computing
power and data rate in WASNs, the MARVELO (Multicast-Aware Routing for Virtual
network Embedding with Loops in Overlays) framework is expanded for use with TRINICON,
while a feature-based selection scheme is proposed to exploit the most beneficial
parts of the input signal for adapting the demixing system. The simulation results
of realistic scenarios show only a minor degradation of the separation performance
even in heavily resource-limited situations.

text: Internet of Things (IoT) applications witness an exceptional evolution of
traffic demands, while existing protocols, as seen in wireless sensor networks
(WSNs), struggle to cope with these demands. Traditional protocols rely on finding
a routing path between sensors generating data and sinks acting as gateway or
databases. Meanwhile, the network will suffer from high collisions in case of
high data rates. In this context, in-network processing solutions are used to
leverage the wireless nodes' computations, by distributing processing tasks on
the nodes along the routing path. Although in-network processing solutions are
very popular in wired networks (e.g., data centers and wide area networks), there
are many challenges to adopt these solutions in wireless networks, due to the
interference problem. In this paper, we solve the problem of routing and task
distribution jointly using a greedy Virtual Network Embedding (VNE) algorithm,
and consider power control as well. Through simulations, we compare the proposed
algorithm to optimal solutions and show that it achieves good results in terms
of delay. Moreover, we discuss its sub-optimality by driving tight lower bounds
and loose upper bounds. We also compare our solution with another wireless VNE
solution to show the trade-off between delay and symbol error rate.

text: One of the major challenges in implementing wireless virtualization is the
resource discovery. This is particularly important for the embedding-algorithms
that are used to distribute the tasks to nodes. MARVELO is a prototype framework
for executing different distributed algorithms on the top of a wireless (802.11)
ad-hoc network. The aim of MARVELO is to select the nodes for running the algorithms
and to define the routing between the nodes. Hence, it also supports monitoring
functionalities to collect information about the available resources and to assist
in profiling the algorithms. The objective of this demo is to show how MAVRLEO
distributes tasks in an ad-hoc network, based on a feedback from our monitoring
tool. Additionally, we explain the work-flow, composition and execution of the
framework.

abstract:
- lang: eng
text: 'We formulate a generic framework for blind source separation (BSS), which
allows integrating data-driven spectro-temporal methods, such as deep clustering
and deep attractor networks, with physically motivated probabilistic spatial methods,
such as complex angular central Gaussian mixture models. The integrated model
exploits the complementary strengths of the two approaches to BSS: the strong
modeling power of neural networks, which, however, is based on supervised learning,
and the ease of unsupervised learning of the spatial mixture models whose few
parameters can be estimated on as little as a single segment of a real mixture
of speech. Experiments are carried out on both artificially mixed speech and true
recordings of speech mixtures. The experiments verify that the integrated models
consistently outperform the individual components. We further extend the models
to cope with noisy, reverberant speech and introduce a cross-domain teacher–student
training where the mixture model serves as the teacher to provide training targets
for the student neural network.'
