Interpretable Multiclass Models for Corporate Credit Rating Capable of Expressing Doubt
Corporate credit rating is a process to classify commercial enterprises based on their creditworthiness. Machine learning algorithms can construct classification models, but in general they do not tend to be 100% accurate. ...
The filament sensor for near real-time detection of cytoskeletal fiber structures.
A reliable extraction of filament data from microscopic images is of high interest in the analysis of acto-myosin structures as early morphological markers in mechanically guided differentiation of human mesenchymal stem ...
Calculation and optimization of thresholds for sets of software metrics
(Springer US, 2011)
In this article, we present a novel algorithmic method for the calculation of thresholds for a metric set. To this aim, machine learning and data mining techniques are utilized. We define a data-driven methodology that can ...
Conservativity of random Markov fibred systems
In this paper we extend results concerning conservativity and the existence of -finite measures to random transformations which admit a countable relative Markov partition.We consider random systems which are locally ...
On finite groups whose Sylow subgroups have a bounded number of generators
(SP Birkhäuser Verlag Basel, 2011)
Let G be a finite non-nilpotent group such that every Sylow subgroup of G is generated by at most δ elements, and such that p is the largest prime dividing |G|. We show that G has a non-nilpotent image G/N, such that N is ...
The Factorization Method for Inverse Problems. By Andreas Kirsch and Natalia Grinberg.
Sparse Deconvolution Methods for Ultrasonic NDT
In this work we present two sparse deconvolution methods for nondestructive testing. The first method is a special matching pursuit (MP) algorithm in order to deconvolve the mixed data (signal and noise), and thus to remove ...
Model-based testing as a service
The quality ofWeb services is an important factor for businesses that advertise or sell their services in the Internet. Failures can directly lead to fewer costumers or security problems. However, the testing of complexWeb ...
Regularized Newton methods for x-ray phase contrast and general imaging problems
Like many other advanced imaging methods, x-ray phase contrast imaging and tomography require mathematical inversion of the observed data to obtain real-space information. While an accurate forward model describing the ...
Die mathematischen Tagebücher von Helmut Hasse 1923 - 1935
(Universitätsverlag Göttingen, 2012)
This book contains the full text of the mathematical notebooks of Helmut Hasse (1898-1979), who was one of the leading mathematicians of the 20th century. The originals have been preserved in the Handschriftenabteilung at ...
