• Two Stage SVM and kNN Text Documents Classifier

  Publication

  • M. Kępa
  • J. Szymański

  - Year 2015

  The paper presents an approach to the large scale text documents classification problem in parallel environments. A two stage classifier is proposed, based on a combination of k-nearest neighbors and support vector machines classification methods. The details of the classifier and the parallelisation of classification, learning and prediction phases are described. The classifier makes use of our method named one-vs-near. It is...

  - Year 2015

  This paper presents a new approach to improve the performance of a css-k-NN classifier for categorization of text documents. The css-k-NN classifier (i.e., a threshold-based variation of a standard k-NN classifier we proposed in [1]) is a lazy-learning instance-based classifier. It does not have parameters associated with features and/or classes of objects, that would be optimized during off-line learning. In this paper we propose...

• Sprzętowa i programowa realizacja algorytmu szyfrującego AES = Hardware and software implementation of AES algorithm

  Publication

  • M. Wójcikowski
  • B. Pankiewicz

  - Year 2006

  W artykule przedstawiono sprzętową i programową realizację algorytmu szyfrującego i deszyfrującego AES. Obydwie implementacje zostały zrealizowane z wykorzystaniem platformy Virtex-II i praktycznie zweryfikowane. Jako kryteria do porównania wybrano: zużycie zasobów, przepustowość i zużycie mocy. Wersja sprzętowa charakteryzuje się 190-krotnie większą przepustowością, 80-krotnie mniejszym zużyciem energii na przetworzenie jednego...

• A Study on Influence of Normalization Methods on Music Genre Classification Results Employing kNN Algorithms

  Publication

  • A. Rosner
  • M. Michalak
  • B. Kostek

  - Studia Informatica Pomerania - Year 2013

  This paper presents a comparison of different normalization methods applied to the set of feature vectors of music pieces. Test results show the influence of min-nlax and Zero-Mean normalization methods, employing different distance functions (Euclidean, Manhattan, Chebyshev, Minkowski) as a pre-processing for genre classification, on k-Nearest Neighbor (kNN) algorithm classification results.

• Interference aware bluetooth scatternet (re)configuration algorithm IBLUERA

  Publication

  • T. Klajbor
  • J. Woźniak

  - Year 2007

  This paper presents a new algorithm IBLUEREA, which enables reconfiguration of Bluetooth scatternet to reduce interference. IBLUEREA makes use of the complex model comparing ISM environment efficiency. The mechanism envisages the use of the assessment of the probability of successful (unsuccessful) frame transmission in order to take a decision concerning co-existence of technologies which make use of the same ISM band (here Bluetooth...
