  abstract     = {{We study the problem of learning choice functions, which play an important
role in various domains of application, most notably in the field of economics.
Formally, a choice function is a mapping from sets to sets: Given a set of
choice alternatives as input, a choice function identifies a subset of most
preferred elements. Learning choice functions from suitable training data comes
with a number of challenges. For example, the sets provided as input and the
subsets produced as output can be of any size. Moreover, since the order in
which alternatives are presented is irrelevant, a choice function should be
symmetric. Perhaps most importantly, choice functions are naturally
context-dependent, in the sense that the preference in favor of an alternative
may depend on what other options are available. We formalize the problem of
learning choice functions and present two general approaches based on two
representations of context-dependent utility functions. Both approaches are
instantiated by means of appropriate neural network architectures, and their
performance is demonstrated on suitable benchmark tasks.}},

  abstract     = {{For optimal placement and orchestration of network services, it is crucial
that their structure and semantics are specified clearly and comprehensively
and are available to an orchestrator. Existing specification approaches are
either ambiguous or miss important aspects regarding the behavior of virtual
network functions (VNFs) forming a service. We propose to formally and
unambiguously specify the behavior of these functions and services using
Queuing Petri Nets (QPNs). QPNs are an established method that allows to
express queuing, synchronization, stochastically distributed processing delays,
and changing traffic volume and characteristics at each VNF. With QPNs,
multiple VNFs can be connected to complete network services in any structure,
even specifying bidirectional network services containing loops.
  We discuss how management and orchestration systems can benefit from our
clear and comprehensive specification approach, leading to better placement of
VNFs and improved Quality of Service. Another benefit of formally specifying
network services with QPNs are diverse analysis options, which allow valuable
insights such as the distribution of end-to-end delay. We propose a tool-based
workflow that supports the specification of network services and the automatic
generation of corresponding simulation code to enable an in-depth analysis of
their behavior and performance.}},

  abstract     = {{Existing approaches and tools for the generation of approximate circuits often lack generality and are restricted to certain circuit types, approximation techniques, and quality assurance methods. Moreover, only few tools are publicly available. This hinders the development and evaluation of new techniques for approximating circuits and their comparison to previous approaches. In this paper, we first analyze and classify related approaches and then present CIRCA, our flexible framework for search-based approximate circuit generation. CIRCA is developed with a focus on modularity and extensibility. We present the architecture of CIRCA with its clear separation into stages and functional blocks, report on the current prototype, and show initial experiments.}},

We present three approaches for the same multi-domain defensive action that can be applied in such an alliance: 1) Counteract Everywhere, 2) Minimize Countermeasures, and 3) Minimize Propagation. First, we provide a formula to compute efficiency of a defense; then we use this formula to compute the efficiency of the approaches under various circumstances. Finally, we discuss how task execution order and timing influence defense efficiency. Our results show that the Minimize Propagation approach is the most efficient method when defending against the chosen attack.}},
