In view of pollution prediction modeling, the study adopts homogenous (random forest, bagging, and additive regression) and heterogeneous (voting) ensemble classifiers to predict the atmospheric concentration of Sulphur dioxide. For model validation, results were compared against widely known single base classifiers such as support vector machine, multilayer perceptron, linear regression and re...

The new voting system of the Council of the European Union cannot be represented as the intersection of six or fewer weighted games, i.e., its dimension is at least 7. This sets a new record for real-world voting bodies. A heuristic combination of different discrete optimization methods yields a representation as the intersection of 13 368 weighted games. Determination of the exact dimension is...

CNG Method for Authorship Attribution. The Common N-Grams (CNG) classification method for authorship attribution (AATT) was described in [2]. The method is based on extracting the most frequent byte n-grams of size n from the training data. The n-grams are sorted by their normalized frequency, and the first L most-frequent n-grams define an author profile. Given a test document, the test profil...

A crucial part for facial expression analysis is to capture a face deformation. In this work, we are interested by the employment of 3D facial surface normals (3DFSN) to classify six basic facial expressions and the proposed approach was employed on the Bosphorus database. We constructed a Principal Component Analysis (PCA) to capture variations in facial shape due to changes in expressions usi...

Binary “yes”–“no” decisions in a legislative committee or shareholder meeting are commonly modeled as weighted game. However, there noteworthy exceptions. E.g., the voting rules of European Council according to Treaty Lisbon use more complicated construction. Here we want study question if lose much from practical point view, restrict ourselves games. To this end, invoke power indices that meas...
