text: "In practical, large-scale networks, services are requested\r\nby users across
the globe, e.g., for video streaming.\r\nServices consist of multiple interconnected
components such as\r\nmicroservices in a service mesh. Coordinating these services\r\nrequires
scaling them according to continuously changing user\r\ndemand, deploying instances
at the edge close to their users,\r\nand routing traffic efficiently between users
and connected instances.\r\nNetwork and service coordination is commonly addressed\r\nthrough
centralized approaches, where a single coordinator\r\nknows everything and coordinates
the entire network globally.\r\nWhile such centralized approaches can reach global
optima, they\r\ndo not scale to large, realistic networks. In contrast, distributed\r\napproaches
scale well, but sacrifice solution quality due to their\r\nlimited scope of knowledge
and coordination decisions.\r\n\r\nTo this end, we propose a hierarchical coordination
approach\r\nthat combines the good solution quality of centralized approaches\r\nwith
the scalability of distributed approaches. In doing so, we divide\r\nthe network
into multiple hierarchical domains and optimize\r\ncoordination in a top-down
manner. We compare our hierarchical\r\nwith a centralized approach in an extensive
evaluation on a real-world\r\nnetwork topology. Our results indicate that hierarchical\r\ncoordination
can find close-to-optimal solutions in a fraction of\r\nthe runtime of centralized
approaches."

text: Word embedding models reflect bias towards genders, ethnicities, and other
social groups present in the underlying training data. Metrics such as ECT, RNSB,
and WEAT quantify bias in these models based on predefined word lists representing
social groups and bias-conveying concepts. How suitable these lists actually are
to reveal bias - let alone the bias metrics in general - remains unclear, though.
In this paper, we study how to assess the quality of bias metrics for word embedding
models. In particular, we present a generic method, Bias Silhouette Analysis (BSA),
that quantifies the accuracy and robustness of such a metric and of the word lists
used. Given a biased and an unbiased reference embedding model, BSA applies the
metric systematically for several subsets of the lists to the models. The variance
and rate of convergence of the bias values of each model then entail the robustness
of the word lists, whereas the distance between the models' values gives indications
of the general accuracy of the metric with the word lists. We demonstrate the
behavior of BSA on two standard embedding models for the three mentioned metrics
with several word lists from existing research.

text: " We show how to construct an overlay network of constant degree and diameter
$O(\\log n)$ in time $O(\\log n)$ starting from an arbitrary weakly connected
graph.\r\n We assume a synchronous communication network in which nodes can
send messages to nodes they know the identifier of and establish new connections
by sending node identifiers.\r\n If the initial network's graph is weakly connected
and has constant degree, then our algorithm constructs the desired topology with
each node sending and receiving only $O(\\log n)$ messages in each round in time
$O(\\log n)$, w.h.p., which beats the currently best $O(\\log^{3/2} n)$ time algorithm
of [Götte et al., SIROCCO'19].\r\n Since the problem cannot be solved faster
than by using pointer jumping for $O(\\log n)$ rounds (which would even require
each node to communicate $\\Omega(n)$ bits), our algorithm is asymptotically optimal.\r\n
\ We achieve this speedup by using short random walks to repeatedly establish
random connections between the nodes that quickly reduce the conductance of the
graph using an observation of [Kwok and Lau, APPROX'14].\r\n \r\n Additionally,
we show how our algorithm can be used to efficiently solve graph problems in \\emph{hybrid
networks} [Augustine et al., SODA'20].\r\n Motivated by the idea that nodes
possess two different modes of communication, we assume that communication of
the \\emph{initial} edges is unrestricted. In contrast, only polylogarithmically
many messages can be communicated over edges that have been established throughout
an algorithm's execution.\r\n For an (undirected) graph $G$ with arbitrary
degree, we show how to compute connected components, a spanning tree, and biconnected
components in time $O(\\log n)$, w.h.p.\r\n Furthermore, we show how to compute
an MIS in time $O(\\log d + \\log \\log n)$, w.h.p., where $d$ is the initial
degree of $G$."

text: Approximate computing (AC) has acquired significant maturity in recent years
as a promising approach to obtain energy and area-efficient hardware. Automated
approximate accelerator synthesis involves a great deal of complexity on the size
of design space which exponentially grows with the number of possible approximations.
Design space exploration of approximate accelerator synthesis is usually targeted
via heuristic-based search methods. The majority of existing frameworks prune
a large part of the design space using a greedy-based approach to keep the problem
tractable. Therefore, they result in inferior solutions since many potential solutions
are neglected in the pruning process without the possibility of backtracking of
removed approximate instances. In this paper, we address the aforementioned issue
by adopting Monte Carlo Tree Search (MCTS), as an efficient stochastic learning-based
search algorithm, in the context of automated synthesis of approximate accelerators.
This enables the synthesis frameworks to deeply subsamples the design space of
approximate accelerator synthesis toward most promising approximate instances
based on the required performance goals, i.e., power consumption, area, or/and
delay. We investigated the challenges of providing an efficient open-source framework
that benefits analytical and search-based approximation techniques simultaneously
to both speed up the synthesis runtime and improve the quality of obtained results.
Besides, we studied the utilization of machine learning algorithms to improve
the performance of several critical steps, i.e., accelerator quality testing,
in the synthesis framework. The proposed framework can help the community to rapidly
generate efficient approximate accelerators in a reasonable runtime.

text: In this publication important aspects for the implementation of inductive
locating are explained. The miniaturized sensor platform called Sens-o-Spheres
is used as an application of this locating method. The sensor platform is applied
in bioreactors in order to obtain the environmental parameters, which makes a
localization by magnetic fields necessary. Since the properties of magnetic fields
in the localization area are very different from the wave characteristics, the
principle of inductive localization is investigated in this publication and explained
by using electrical equivalent circuit diagrams. Thereby, inductive localization
uses the coupling or the mutual inductivities between coils, which is noticeable
by an induced voltage. Therefore some properties and procedures are explained
to extract the location of Sens-o-Spheres or other industrial sensor platforms
from the couplings of the coils. One method calculates the location from an adapted
ratio calculation and the other method uses neural networks and stochastic filters
to obtain the results. In the end, these results are evaluated and compared.

text: During the industrial processing of materials for the manufacture of new products,
surface defects can quickly occur. In order to achieve high quality without a
long time delay, it makes sense to inspect the work pieces so that defective work
pieces can be sorted out right at the beginning of the process. At the same time,
the evaluation unit should come close the perception of the human eye regarding
detection of defects in surfaces. Such defects often manifest themselves by a
deviation of the existing structure. The only restriction should be that only
matt surfaces should be considered here. Therefore in this work, different classification
and image processing algorithms are applied to surface data to identify possible
surface damages. For this purpose, the Gabor filter and the FST (Fused Structure
and Texture) features generated with it, as well as the salience metric are used
on the image processing side. On the classification side, however, deep neural
networks, Convolutional Neural Networks (CNN), and autoencoders are used to make
a decision. A distinction is also made between training using class labels and
without. It turns out later that the salience metric are best performed by CNN.
On the other hand, if there is no labeled training data available, a novelty classification
can easily be achieved by using autoencoders as well as the salience metric and
some filters.

text: This bachelor thesis presents a C/C++ implementation of the XCS algorithm
for an embedded system and profiling results concerning the execution time of
the functions. These are then analyzed in relation to the input characteristics
of the examined learning environments and compared with related work. Three main
conclusions can be drawn from the measured results. First, the maximum size of
the population of the classifiers influences the runtime of the genetic algorithm;
second, the size of the input space has a direct effect on the execution time
of the matching function; and last, a larger action space results in a longer
runtime generating the prediction for the possible actions. The dependencies identified
here can serve to optimize the computational efficiency and make XCS more suitable
for embedded systems.

text: 'Over the past decades, the Gathering problem, which asks to gather a group
of robots in finite time given some restrictions, has been intensively studied.
In this paper, we are given a group of n autonomous, dimensionless, deterministic,
and anonymous robots, with bounded viewing range. Assuming a continuous time model,
the goal is to gather these robots into one point in finite time. We introduce
a simple convergence criterion that defines a new class of algorithms which perform
gathering in O(nd) time, where d is the diameter of the initial robot configuration.
We show that some gathering algorithms in the literature belong to this class
and propose two new algorithms that belong to this class and have quadratic running
time, namely, Go-To-The-Relative-Center algorithm (GTRC) and Safe-Go-To-The-Relative-Center
algorithm (S-GTRC). We prove that the latter can perform gathering without collision
by using a slightly more complex robot model: non oblivious, chiral, and luminous
(i.e. robots have observable external memory, as in [8]). We also consider a variant
of the Gathering problem, the Near-Gathering problem, in which robots must get
close to each other without colliding. We show that S-GTRC solves the Near-Gathering
problem in quadratic time and assumes a weaker robot model than the one assumed
in the current state-of-the-art.'
