text: "Dynamic allocation of resources is a key feature in network function virtualization
(NFV), enabling flexible adjustment of slices and contained network services to
ever-changing service demands. \r\nConsidering resource allocation across the
entire network, many authors have proposed approaches to optimize the placement
and chaining of virtual network function (VNF) instances and the allocation of
resources to these VNF instances. In doing so, various optimization objectives
are conceivable, e.g., minimizing certain required resources or the end-to-end
delay of the placed services.\r\n\r\nIn this paper, we investigate the relationship
between four typical optimization objectives when coordinating the placement and
resource allocation of chained VNF instances. We observe an interesting trade-off
between minimizing the overhead of starting/stopping VNF instances and all other
objectives when adapting to changed service demands."

text: "In recent years, a variety of different approaches\r\nhave been proposed
to tackle the problem of scaling and placing\r\nnetwork services, consisting of
interconnected virtual network\r\nfunctions (VNFs). This paper presents a placement
abstraction\r\nlayer (PAL) that provides a clear and simple northbound interface\r\nfor
using such algorithms while hiding their internal\r\nfunctionality and implementation.
Through its southbound interface,\r\nPAL can connect to different back ends that
evaluate\r\nthe calculated placements, e.g., using simulations, emulations, or\r\ntestbed
approaches. As an example for such evaluation back ends,\r\nwe introduce a novel
placement emulation framework (PEF)\r\nthat allows executing calculated placements
using real, containerbased\r\nVNFs on real-world network topologies. In a case
study,\r\nwe show how PAL and PEF facilitate reusing and evaluating\r\nplacement
algorithms as well as validating their underlying\r\nmodels and performance claims."

text: "A key challenge of network function virtualization\r\n(NFV) is the complexity
of developing and deploying new\r\nnetwork services. Currently, development requires
many manual\r\nsteps that are time-consuming and error-prone (e.g., for creating\r\nservice
descriptors). Furthermore, existing management and\r\norchestration (MANO) platforms
only offer limited support of\r\nstandardized descriptor models or package formats,
limiting the\r\nre-usability of network services.\r\n\r\nTo this end, we introduce
a fully integrated, open-source\r\nNFV service development kit (SDK) with multi-MANO
platform\r\nsupport. Our SDK simplifies many NFV service development\r\nsteps
by offering initial generation of descriptors, advanced\r\nproject management,
as well as fully automated packaging and\r\nsubmission for on-boarding. To achieve
multi-platform support,\r\nwe present a package format that extends ETSI’s VNF
package\r\nformat. In this demonstration, we present the end-to-end workflow\r\nto
develop an NFV service that is then packaged for multiple\r\nplatforms, i.e.,
5GTANGO and OSM."

text: Acoustic event detection, i.e., the task of assigning a human interpretable
label to a segment of audio, has only recently attracted increased interest in
the research community. Driven by the DCASE challenges and the availability of
large-scale audio datasets, the state-of-the-art has progressed rapidly with deep-learning-based
classi- fiers dominating the field. Because several potential use cases favor
a realization on distributed sensor nodes, e.g. ambient assisted living applications,
habitat monitoring or surveillance, we are concerned with two issues here. Firstly
the classification performance of such systems and secondly the computing resources
required to achieve a certain performance considering node level feature extraction.
In this contribution we look at the balance between the two criteria by employing
traditional techniques and different deep learning architectures, including convolutional
and recurrent models in the context of real life everyday audio recordings in
realistic, however challenging, multisource conditions.

text: "The main idea in On-The-Fly Computing is to automatically compose existing
software services according to the wishes of end-users. However, since user requirements
are often ambiguous, vague and incomplete, the selection and composition of suitable
software services is a challanging task. In this paper, we present our current
approach to improve requirement descriptions before they are used for software
composition. This procedure is fully automated, but also has limitations, for
example, if necessary information is missing. In addition, and in response to
the limitations, we provide insights into our above-mentioned current work that
combines the existing optimization approach with a\r\nchatbot solution."

text: Natural language requirement descriptions are often unstructured, contradictory
and incomplete and are therefore challenging for automatic processing. Although
many of these deficits can be compensated by means of Natural Language Processing,
there still remain cases where interaction with end-users is necessary for clarification.
In this paper, we present our idea of using chatbot technology to establish end-user
communication in order to support the automatic compensation of some deficits
in natural language requirement descriptions.

text: "As our world grows in complexity, companies and employees alike need, more
than ever before, solutions tailored to their exact needs. Since such tools cannot
always be purchased off-the-shelf and need to be designed from the ground up,
developers rely on software requirements. In this paper, we present our vision
of a syntactic rule-based extraction\r\ntool for software requirements specification
documents. In contrast to other methods, our tool will allow stakeholders to express
their needs and wishes in unfiltered natural language, which we believe is essential
for non-expert users."

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. But in its original formulation, WPE requires multiple iterations
over a sufficiently long utterance, rendering it unsuitable for online low-latency
applications. Recently, two methods have been proposed to overcome this limitation.
One utilizes a neural network to estimate the power spectral density (PSD) of
the target signal and works in a block-online fashion. The other method relies
on a rather simple PSD estimation which smoothes the observed PSD and utilizes
a recursive formulation which enables it to work on a frame-by-frame basis. In
this paper, we integrate a deep neural network (DNN) based estimator into the
recursive frame-online formulation. We evaluate the performance of the recursive
system with different PSD estimators in comparison to the block-online and offline
variant on two distinct corpora. The REVERB challenge data, where the signal is
mainly deteriorated by reverberation, and a database which combines WSJ and VoiceHome
to also consider (directed) noise sources. The results show that although smoothing
works surprisingly well, the more sophisticated DNN based estimator shows promising
improvements and shortens the performance gap between online and offline processing.

text: We present a block-online multi-channel front end for automatic speech recognition
in noisy and reverberated environments. It is an online version of our earlier
proposed neural network supported acoustic beamformer, whose coefficients are
calculated from noise and speech spatial covariance matrices which are estimated
utilizing a neural mask estimator. However, the sparsity of speech in the STFT
domain causes problems for the initial beamformer coefficients estimation in some
frequency bins due to lack of speech observations. We propose two methods to mitigate
this issue. The first is to lower the frequency resolution of the STFT, which
comes with the additional advantage of a reduced time window, thus lowering the
latency introduced by block processing. The second approach is to smooth beamforming
coefficients along the frequency axis, thus exploiting their high interfrequency
correlation. With both approaches the gap between offline and block-online beamformer
performance, as measured by the word error rate achieved by a downstream speech
recognizer, is significantly reduced. Experiments are carried out on two copora,
representing noisy (CHiME-4) and noisy reverberant (voiceHome) environments.

text: 'The weighted prediction error (WPE) algorithm has proven to be a very successful
dereverberation method for the REVERB challenge. Likewise, neural network based
mask estimation for beamforming demonstrated very good noise suppression in the
CHiME 3 and CHiME 4 challenges. Recently, it has been shown that this estimator
can also be trained to perform dereverberation and denoising jointly. However,
up to now a comparison of a neural beamformer and WPE is still missing, so is
an investigation into a combination of the two. Therefore, we here provide an
extensive evaluation of both and consequently propose variants to integrate deep
neural network based beamforming with WPE. For these integrated variants we identify
a consistent word error rate (WER) reduction on two distinct databases. In particular,
our study shows that deep learning based beamforming benefits from a model-based
dereverberation technique (i.e. WPE) and vice versa. Our key findings are: (a)
Neural beamforming yields the lower WERs in comparison to WPE the more channels
and noise are present. (b) Integration of WPE and a neural beamformer consistently
outperforms all stand-alone systems.'

text: NARA-WPE is a Python software package providing implementations of the weighted
prediction error (WPE) dereverberation algorithm. WPE has been shown to be a highly
effective tool for speech dereverberation, thus improving the perceptual quality
of the signal and improving the recognition performance of downstream automatic
speech recognition (ASR). It is suitable both for single-channel and multi-channel
applications. The package consist of (1) a Numpy implementation which can easily
be integrated into a custom Python toolchain, and (2) a TensorFlow implementation
which allows integration into larger computational graphs and enables backpropagation
through WPE to train more advanced front-ends. This package comprises of an iterative
offline (batch) version, a block-online version, and a frame-online version which
can be used in moderately low latency applications, e.g. digital speech assistants.

text: We present an experimental comparison of seven state-of-the-art machine learning
algorithms for the task of semantic analysis of spoken input, with a special emphasis
on applications for dysarthric speech. Dysarthria is a motor speech disorder,
which is characterized by poor articulation of phonemes. In order to cater for
these noncanonical phoneme realizations, we employed an unsupervised learning
approach to estimate the acoustic models for speech recognition, which does not
require a literal transcription of the training data. Even for the subsequent
task of semantic analysis, only weak supervision is employed, whereby the training
utterance is accompanied by a semantic label only, rather than a literal transcription.
Results on two databases, one of them containing dysarthric speech, are presented
showing that Markov logic networks and conditional random fields substantially
outperform other machine learning approaches. Markov logic networks have proved
to be especially robust to recognition errors, which are caused by imprecise articulation
in dysarthric speech.

text: Deep clustering (DC) and deep attractor networks (DANs) are a data-driven
way to monaural blind source separation. Both approaches provide astonishing single
channel performance but have not yet been generalized to block-online processing.
When separating speech in a continuous stream with a block-online algorithm, it
needs to be determined in each block which of the output streams belongs to whom.
In this contribution we solve this block permutation problem by introducing an
additional speaker identification embedding to the DAN model structure. We motivate
this model decision by analyzing the embedding topology of DC and DANs and show,
that DC and DANs themselves are not sufficient for speaker identification. This
model structure (a) improves the signal to distortion ratio (SDR) over a DAN baseline
and (b) provides up to 61% and up to 34% relative reduction in permutation error
rate and re-identification error rate compared to an i-vector baseline, respectively.

text: 'Deep attractor networks (DANs) are a recently introduced method to blindly
separate sources from spectral features of a monaural recording using bidirectional
long short-term memory networks (BLSTMs). Due to the nature of BLSTMs, this is
inherently not online-ready and resorting to operating on blocks yields a block
permutation problem in that the index of each speaker may change between blocks.
We here propose the joint modeling of spatial and spectral features to solve the
block permutation problem and generalize DANs to multi-channel meeting recordings:
The DAN acts as a spectral feature extractor for a subsequent model-based clustering
approach. We first analyze different joint models in batch-processing scenarios
and finally propose a block-online blind source separation algorithm. The efficacy
of the proposed models is demonstrated on reverberant mixtures corrupted by real
recordings of multi-channel background noise. We demonstrate that both the proposed
batch-processing and the proposed block-online system outperform (a) a spatial-only
model with a state-of-the-art frequency permutation solver and (b) a spectral-only
model with an oracle block permutation solver in terms of signal to distortion
ratio (SDR) gains.'

text: This work examines acoustic beamformers employing neural networks (NNs) for
mask prediction as front-end for automatic speech recognition (ASR) systems for
practical scenarios like voice-enabled home devices. To test the versatility of
the mask predicting network, the system is evaluated with different recording
hardware, different microphone array designs, and different acoustic models of
the downstream ASR system. Significant gains in recognition accuracy are obtained
in all configurations despite the fact that the NN had been trained on mismatched
data. Unlike previous work, the NN is trained on a feature level objective, which
gives some performance advantage over a mask related criterion. Furthermore, different
approaches for realizing online, or adaptive, NN-based beamforming are explored,
where the online algorithms still show significant gains compared to the baseline
performance.
