| Abstract(in English) | When we apply independent component analysis (ICA for short) to extraction of some information sources from given observations, the results often depend on initial settings of the algorithm. In somes cases, we cannot find the required resuluts by any setting in ICA. In this paper, we apply Tsallis mutual entropy, one-parameter generalization of Shannon mutual entropy, to ICA and reports the effects of the new parameter (q ∈ [0,1]) in iCA. In particular, we take the examples which the usual ICA using Shannon mutual entropy cannot succeed to extract. It is shown that the application of Tsallis mutual entropy to ICA for such examples enables us to succeed in the extraction. The effect of the new parameter q in the learning is also discussed. |
