text: "Unsupervised blind source separation methods do not require a training phase\r\nand
thus cannot suffer from a train-test mismatch, which is a common concern in\r\nneural
network based source separation. The unsupervised techniques can be\r\ncategorized
in two classes, those building upon the sparsity of speech in the\r\nShort-Time
Fourier transform domain and those exploiting non-Gaussianity or\r\nnon-stationarity
of the source signals. In this contribution, spatial mixture\r\nmodels which fall
in the first category and independent vector analysis (IVA)\r\nas a representative
of the second category are compared w.r.t. their separation\r\nperformance and
the performance of a downstream speech recognizer on a\r\nreverberant dataset
of reasonable size. Furthermore, we introduce a serial\r\nconcatenation of the
two, where the result of the mixture model serves as\r\ninitialization of IVA,
which achieves significantly better WER performance than\r\neach algorithm individually
and even approaches the performance of a much more\r\ncomplex neural network based
technique."

text: Due to the ad hoc nature of wireless acoustic sensor networks, the position
of the sensor nodes is typically unknown. This contribution proposes a technique
to estimate the position and orientation of the sensor nodes from the recorded
speech signals. The method assumes that a node comprises a microphone array with
synchronously sampled microphones rather than a single microphone, but does not
require the sampling clocks of the nodes to be synchronized. From the observed
audio signals, the distances between the acoustic sources and arrays, as well
as the directions of arrival, are estimated. They serve as input to a non-linear
least squares problem, from which both the sensor nodes’ positions and orientations,
as well as the source positions, are alternatingly estimated in an iterative process.
Given one set of unknowns, i.e., either the source positions or the sensor nodes’
geometry, the other set of unknowns can be computed in closed-form. The proposed
approach is computationally efficient and the first one, which employs both distance
and directional information for geometry calibration in a common cost function.
Since both distance and direction of arrival measurements suffer from outliers,
e.g., caused by strong reflections of the sound waves on the surfaces of the room,
we introduce measures to deemphasize or remove unreliable measurements. Additionally,
we discuss modifications of our previously proposed deep neural network-based
acoustic distance estimator, to account not only for omnidirectional sources but
also for directional sources. Simulation results show good positioning accuracy
and compare very favorably with alternative approaches from the literature.

text: 'In this work we address disentanglement of style and content in speech signals.
We propose a fully convolutional variational autoencoder employing two encoders:
a content encoder and a style encoder. To foster disentanglement, we propose adversarial
contrastive predictive coding. This new disentanglement method does neither need
parallel data nor any supervision. We show that the proposed technique is capable
of separating speaker and content traits into the two different representations
and show competitive speaker-content disentanglement performance compared to other
unsupervised approaches. We further demonstrate an increased robustness of the
content representation against a train-test mismatch compared to spectral features,
when used for phone recognition.'

text: Phase-shift modulated full bridge converters suffer from thermal imbalances
of the inverter switches. The lagging leg switches are subject to larger commutation
currents compared to those of the leading leg as the transformer current reduces
in the freewheeling interval. Furthermore, after this interval, the energy in
the series inductance may not be large enough to achieve zero-voltage switching
(ZVS) for the leading leg. Both effects result in thermal imbalances. This paper
analyzes the alternating-asymmetrical phase-shift modulation to achieve balanced
conduction and switching losses for all four switches while showing that this
modulation is easily implemented on standard DSPs. The modulation has been implemented
to LLC converters where experimental measurement results proved its effectiveness
for LLC converters by reducing the temperature deviation from 6.3 K to only 0.2
K such that the peak temperature is reduced from 95 °C to 92 °C. The paper also
proves that the modulation can be utilized to improve the efficiency of LLC converters
operated at very low gains while simultaneously reducing the junction temperature
of all four switches compared to the conventional complementary modulation. Finally,
EMI implications are analyzed, which show that the modulation may be beneficial
for reducing the common-mode emissions around the operating frequency.

text: "Automatic transcription of meetings requires handling of overlapped speech,
which calls for continuous speech separation (CSS) systems. The uPIT criterion
was proposed for utterance-level separation with neural networks and introduces
the constraint that the total number of speakers must not exceed the number of
output channels. When processing meeting-like data in a segment-wise manner, i.e.,
by separating overlapping segments independently and stitching adjacent segments
to continuous output streams, this constraint has to be fulfilled for any segment.
In this contribution, we show that this constraint can be significantly relaxed.
We propose a novel graph-based PIT criterion, which casts the assignment of utterances
to output channels in a graph coloring problem. It only requires that the number
of concurrently active speakers must not exceed the number of output channels.
As a consequence, the system can process an arbitrary number of speakers and arbitrarily
long segments and thus can handle more diverse scenarios.\r\nFurther, the stitching
algorithm for obtaining a consistent output order in neighboring segments is of
less importance and can even be eliminated completely, not the least reducing
the computational effort. Experiments on meeting-style WSJ data show improvements
in recognition performance over using the uPIT criterion. "

text: 'In this paper we present our system for the Detection and Classification
of Acoustic Scenes and Events (DCASE) 2021 Challenge Task 4: Sound Event Detection
and Separation in Domestic Environments, where it scored the fourth rank. Our
presented solution is an advancement of our system used in the previous edition
of the task.We use a forward-backward convolutional recurrent neural network (FBCRNN)
for tagging and pseudo labeling followed by tag-conditioned sound event detection
(SED) models which are trained using strong pseudo labels provided by the FBCRNN.
Our advancement over our earlier model is threefold. First, we introduce a strong
label loss in the objective of the FBCRNN to take advantage of the strongly labeled
synthetic data during training. Second, we perform multiple iterations of self-training
for both the FBCRNN and tag-conditioned SED models. Third, while we used only
tag-conditioned CNNs as our SED model in the previous edition we here explore
sophisticated tag-conditioned SED model architectures, namely, bidirectional CRNNs
and bidirectional convolutional transformer neural networks (CTNNs), and combine
them. With metric and class specific tuning of median filter lengths for post-processing,
our final SED model, consisting of 6 submodels (2 of each architecture), achieves
on the public evaluation set poly-phonic sound event detection scores (PSDS) of
0.455 for scenario 1 and 0.684 for scenario as well as a collar-based F1-score
of 0.596 outperforming the baselines and our model from the previous edition by
far. Source code is publicly available at https://github.com/fgnt/pb_sed.'

text: Recently, there has been a rising interest in sound recognition via Acoustic
Sensor Networks to support applications such as ambient assisted living or environmental
habitat monitoring. With state-of-the-art sound recognition being dominated by
deep-learning-based approaches, there is a high demand for labeled training data.
Despite the availability of large-scale data sets such as Google's AudioSet,
acquiring training data matching a certain application environment is still often
a problem. In this paper we are concerned with human activity monitoring in a
domestic environment using an ASN consisting of multiple nodes each providing
multichannel signals. We propose a self-training based domain adaptation approach,
which only requires unlabeled data from the target environment. Here, a sound
recognition system trained on AudioSet, the teacher, generates pseudo labels for
data from the target environment on which a student network is trained. The student
can furthermore glean information about the spatial arrangement of sensors and
sound sources to further improve classification performance. It is shown that the
student significantly improves recognition performance over the pre-trained teacher
without relying on labeled data from the environment the system is deployed in.

text: One objective of current research in explainable intelligent systems is to
implement social aspects in order to increase the relevance of explanations. In
this paper, we argue that a novel conceptual framework is needed to overcome shortcomings
of existing AI systems with little attention to processes of interaction and learning.
Drawing from research in interaction and development, we first outline the novel
conceptual framework that pushes the design of AI systems toward true interactivity
with an emphasis on the role of the partner and social relevance. We propose that
AI systems will be able to provide a meaningful and relevant explanation only
if the process of explaining is extended to active contribution of both partners
that brings about dynamics that is modulated by different levels of analysis.
Accordingly, our conceptual framework comprises monitoring and scaffolding as
key concepts and claims that the process of explaining is not only modulated by
the interaction between explainee and explainer but is embedded into a larger
social context in which conventionalized and routinized behaviors are established.
We discuss our conceptual framework in relation to the established objectives
of transparency and autonomy that are raised for the design of explainable AI
systems currently.

text: We present a combined experimental and numerical study of the far-field emission
properties of optical travelling wave antennas made from low-loss dielectric materials.
The antennas considered here are composed of two simple building blocks, a director
and a reflector, deposited on a glass substrate. Colloidal quantum dots placed
in the feed gap between the two elements serve as internal light source. The emission
profile of the antenna is mainly formed by the director while the reflector suppresses
backward emission. Systematic studies of the director dimensions as well as variation
of antenna material show that the effective refractive index of the director primarily
governs the far-field emission pattern. Below cut off, i.e., if the director’s
effective refractive index is smaller than the refractive index of the substrate,
the main lobe results from leaky wave emission along the director. In contrast,
if the director supports a guided mode, the emission predominately originates
from the end facet of the director.
