On Estimation of a Quantity of Base Models with Parametric z and Permutation Tests
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)
One of the crucial problems in multiple-model approach of the regression is
estimation of optimal number of base models. If the quantity is too low – it increases the
prediction error whereas too high number of models ...
Sequence of Experimental Trials and Factorial Design of Experiment Realization Costs
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)
Design of experiment is one of statistical methods of quality control which allows
to appropriate preparation of the production process. Statistical design of experiment allows to set
the level and to determine the ...
Stepwise Multiple Tests Procedures for Discrete Distributions
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)
We presented some properties of new procedures of multiple hypotheses testing for
discrete distributions. We choose the new procedure stepwise TWWk, based on Tarone, Westfall
and Welfinger ideas. We compare this procedure ...
Extracting Class Description from Support Vector Machines
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)
Support Vector Machines (SVMs) belong to the group of Data Mining and Machine
Learning methods. SVMs are considered to be one of the best classification methods in
terms of performance measure. The biggest disadvantage ...
Some Remarks on Feature Ranking Based Wrappers
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)
One of the approaches to feature selection in discrimination or regression is
learning models using various feature subsets and evaluating these subsets, basing on model
quality criterion (so called wrappers). Heuristic ...
Comparison of Accuracy of Affinity Propagation Method and Cluster Ensembles Based on Co-Occurrence Matrix
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)
High accuracy of results is a very important task in any grouping problem
(clustering). It determines effectiveness of the decisions based on them. Therefore in the literature
there are proposed methods and solutions ...
Influence of Unemployed Person Age on the Hazard and its Changes in Time
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)
The aim of the article is to analyse the influence of unemployed person’s age on
job seeking time. This influence can changes in time. That analysis is possible by using Cox nonproportional
hazard model. We get the marks ...
Cluster Analysis – Symbolic vs. Classical Data
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)
Clustering problem is addressed in many contexts and disciplines. Although there
are numerous studies on cluster analysis, there is a lack of a review to complete and systematize
knowledge of research approach depending ...
