The calculation results of the function y ¼ gðxt
x1; xt
xþ1;MÞ shows that each state of the cell’s neighbors ðst
x1; st
xþ1Þ can be
recognized exactly by the recognition function y ¼ gðst
x1; st
xþ1;MÞ and the state of the cell’s neighbors can also be exactly represented
by each element mij ði; j ¼ 1; 2Þ in the recognition matrix M.
