Opis:: A new clustering method of fuzzy c-myriad clustering with partial supervision is presented in this paper. The proposed method has been applied to breast cancer diagnosis data obtainted from the University of Wisconsin. The data set contains 699 cases of breast cancer, with each instance described by 10 features.

Opis:: Biomedical signals are commonly recorded with many kinds of noise. One of these is a waveform of the electrical activity of muscles. This "natural" distortion is usually modelled with a white Gaussian noise. In order to suppress such noise a weighted myriad filter is applied. The weighted myriad filter belongs to a class of non-linear filters and requires knowledge about noise impulsiveness. An impulsive noise can be described with alpha-stable distributions. One objective of this paper is to apply alpha-stable distribution as a model of real-life muscle noise in ECG signals. The other objective of the paper is to apply a weighted myriad filter to suppress impulsive noise in biomedical (ECG) signals. The reference filters have been the Savitzky-Golay smoothing filter and the median filter. The obtained results have shown that alpha-stable distributions can be applied to model muscle noise and that a weighted myriad filter with a Chebyshev weighted function can effectively suppress such noise.
