...This is an attempt to understand the nervous system. First, the mathematical model by WSMcCulloch and WHPitts (1943) is known as a formulation of the threshold function of a neuron, that is, the property that a certain amount of output is produced only when the sum of the inputs exceeds a certain value. If the multiple inputs of a neuron are x i ( i = 1, 2, ..., n ), the coupling coefficients for each input are ω i , and the threshold is h , the output x is given by ... *Some of the terminology references "Pitts, WH" are listed below.

…これによって,神経系を理解しようというものである。 まず,神経細胞の閾作用,すなわち入力の和がある値をこえたときのみ,一定の大きさの出力がでるという性質を定式化したものとして,マカロックW.S.McCullochとピッツW.H.Pittsの数学モデル(1943)が知られている。神経細胞の複数の入力をxi(i=1,2,……,n),それぞれの入力に対する結合係数をωi,閾値をhとしたとき,出力xはで与えられるとする。… ※「Pitts,W.H.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
