text: "We address the general mathematical problem of computing the inverse p-th\r\nroot
of a given matrix in an efficient way. A new method to construct iteration\r\nfunctions
that allow calculating arbitrary p-th roots and their inverses of\r\nsymmetric
positive definite matrices is presented. We show that the order of\r\nconvergence
is at least quadratic and that adaptively adjusting a parameter q\r\nalways leads
to an even faster convergence. In this way, a better performance\r\nthan with
previously known iteration schemes is achieved. The efficiency of the\r\niterative
functions is demonstrated for various matrices with different\r\ndensities, condition
numbers and spectral radii."

text: "Spontaneous formation of transverse patterns is ubiquitous in nonlinear\r\ndynamical
systems of all kinds. An aspect of particular interest is the active\r\ncontrol
of such patterns. In nonlinear optical systems this can be used for\r\nall-optical
switching with transistor-like performance, for example realized\r\nwith polaritons
in a planar quantum-well semiconductor microcavity. Here we\r\nfocus on a specific
configuration which takes advantage of the intricate\r\npolarization dependencies
in the interacting optically driven polariton system.\r\nBesides detailed numerical
simulations of the coupled light-field exciton\r\ndynamics, in the present paper
we focus on the derivation of a simplified\r\npopulation competition model giving
detailed insight into the underlying\r\nmechanisms from a nonlinear dynamical
systems perspective. We show that such a\r\nmodel takes the form of a generalized
Lotka-Volterra system for two competing\r\npopulations explicitly including a
source term that enables external control.\r\nWe present a comprehensive analysis
both of the existence and stability of\r\nstationary states in the parameter space
spanned by spatial anisotropy and\r\nexternal control strength. We also construct
phase boundaries in non-trivial\r\nregions and characterize emerging bifurcations.
The population competition\r\nmodel reproduces all key features of the switching
observed in full numerical\r\nsimulations of the rather complex semiconductor
system and at the same time is\r\nsimple enough for a fully analytical understanding
of the system dynamics."

doping in conjugated polymers is a crucial process for their application in organic\r\nphotovoltaics
and optoelectronics. In the present work we theoretically investigate p-type molecu-\r\nlar
doping in a series of (poly[2,6-(4,4-bis(2-ethylhexyl)-4H-cyclopenta[2,1-b;3,4-b”]dithiophene)-alt-\r\n4,7-(2,1,3-benzothiadiazole)]
(PCPDT-BT) conjugated oligomers with different lengths and three\r\nwidely-used
dopants with different electron affinities, namely F4TCNQ, F6TCNNQ, and CN6-CP.\r\nWe
study in detail the molecular geometry of possible oligomer-dopant complexes and
its influence\r\non the doping mechanisms and electronic system properties. We
find that the mechanisms of dop-\r\ning and charge transfer observed sensitively
depend on the specific geometry of the oligomer-dopant\r\ncomplexes. For a given
complex different geometries may exist, some of which show transfer of\r\nan entire
electron from the oligomer chain onto the dopant molecule resulting in an integer-charge\r\ntransfer
complex, leaving the system in a ground state with broken spin symmetry. In other
ge-\r\nometries merely hybridization of oligomer and dopant frontier orbitals
occurs with partial charge\r\ntransfer but spin-symmetric ground state. Considering
the resulting electronic density of states both\r\ncases may well contribute to
an increased electrical conductivity of corresponding film samples while\r\nthe
underlying physical mechanisms are entirely different.\r\n</p>\r\n\t\t\t\t</div>\r\n\t\t\t</div>\r\n\t\t</div>"

text: "Object ranking is an important problem in the realm of preference learning.\r\nOn
the basis of training data in the form of a set of rankings of objects,\r\nwhich
are typically represented as feature vectors, the goal is to learn a\r\nranking
function that predicts a linear order of any new set of objects.\r\nCurrent approaches
commonly focus on ranking by scoring, i.e., on learning an\r\nunderlying latent
utility function that seeks to capture the inherent utility\r\nof each object.
These approaches, however, are not able to take possible\r\neffects of context-dependence
into account, where context-dependence means that\r\nthe utility or usefulness
of an object may also depend on what other objects\r\nare available as alternatives.
In this paper, we formalize the problem of\r\ncontext-dependent ranking and present
two general approaches based on two\r\nnatural representations of context-dependent
ranking functions. Both approaches\r\nare instantiated by means of appropriate
neural network architectures, which\r\nare evaluated on suitable benchmark task."

text: Automated machine learning (AutoML) seeks to automatically select, compose,
and parametrize machine learning algorithms, so as to achieve optimal performance
on a given task (dataset). Although current approaches to AutoML have already
produced impressive results, the field is still far from mature, and new techniques
are still being developed. In this paper, we present ML-Plan, a new approach to
AutoML based on hierarchical planning. To highlight the potential of this approach,
we compare ML-Plan to the state-of-the-art frameworks Auto-WEKA, auto-sklearn,
and TPOT. In an extensive series of experiments, we show that ML-Plan is highly
competitive and often outperforms existing approaches.

text: 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.

text: 'In scientific computing, unstructured meshes are a crucial foundation for
the simulation of real-world physical phenomena. Compared to regular grids, they
allow resembling the computational domain with a much higher accuracy, which in
turn leads to more efficient computations.
There exists a wealth of supporting
libraries and frameworks that aid programmers with the implementation of applications
working on such grids, each built on top of existing parallelization technologies.
However, many approaches require the programmer to introduce a different programming
paradigm into their application or provide different variants of the code. SYCL
is a new programming standard providing a remedy to this dilemma by building on
standard C ++17 with its so-called single-source approach: Programmers write standard
C ++ code and expose parallelism using C++17 keywords. The application is
then
transformed into a concrete implementation by the SYCL implementation. By encapsulating
the OpenCL ecosystem, different SYCL implementations enable not only the programming
of CPUs but also of heterogeneous platforms such as GPUs or other devices. For
the first time, this paper showcases a SYCL-
based solver for the nodal Discontinuous
Galerkin method for Maxwell’s equations on unstructured meshes. We compare our
solution to a previous C-based implementation with respect to programmability
and performance on heterogeneous platforms.Proceedings of the 29th Annual IEEE International

abstract:
- lang: eng
text: In multinomial classification, reduction techniques are commonly used to decompose
the original learning problem into several simpler problems. For example, by recursively
bisecting the original set of classes, so-called nested dichotomies define a set
of binary classification problems that are organized in the structure of a binary
tree. In contrast to the existing one-shot heuristics for constructing nested
dichotomies and motivated by recent work on algorithm configuration, we propose
a genetic algorithm for optimizing the structure of such dichotomies. A key component
of this approach is the proposed genetic representation that facilitates the application
of standard genetic operators, while still supporting the exchange of partial
solutions under recombination. We evaluate the approach in an extensive experimental
study, showing that it yields classifiers with superior generalization performance.
