Описується математична модель нейронної схеми типу «K-winners-take-all» (KWTA), призначеної для ідентифікації К максимальних серед N невідомих сигналів, де $1≤K<N$. Аналізується обробка моделлю постійних дискретизованих вхідних сигналів. Розглядається випадок рівних між собою вхідних сигналів. Наводяться відповідні результати комп’ютерного моделювання.
Mathematical model of discrete-time K-winners-take-all (KWTA) neural circuit that can identify K maximal from N unknown signals, where $1≤K<N$ is described. A processing of constant sampled signals is analyzed. The case of equal input signals is considered. Corresponding computer simulation results are given.
