When sent a list of numbers , it outputs the index of the known vector that matches most closely. The quality of the match is the dot product of the two vectors after normalizing them , i.e. , the vector whose direction is closest to that of the input wins. ; #X text 19 340 If given a nonzero creation argument , choice tries to avoid repetitious outputs by weighting less recently output vectors preferentially.; #X text 20 389 You can use this to choose interactively between a number of behaviors depending on their attributes. For example , you might have stored a number of melodies , of which some are syncopated , some chromatic , some are more than 100 years old , some are bugle calls , and some are Christmas carols. You could then ask to find a syncopated bugle call (1 , 0 , 0 , 1 , 0) and you'll get the thing most closely matching the request.; #X text 19 514 You can use numbers other than 0 and 1 to indicate relative strengths of the attributes , or even use negative numbers to indicate opposites , either in the incoming lists or in the stored ones.; #X text 320 572 updated for Pd version-0.30; #X text 79 62 delete all stored vectors; #X text 498 34 add vectors; #X text 94 84 debugging printout; #X text 69 104 tweak the numbers and hit "bang" to input a list; #X text 151 197 creation argument to avoid repeated outout; #X text 108 219 output is the index of best match , counting from zero; #X connect 0 0 10 0; #X connect 1 0 0 0; #X connect 2 0 0 0; #X connect 2 0 11 0; #X connect 3 0 0 0; #X connect 3 0 11 0; #X connect 4 0 0 0; #X connect 4 0 11 0; #X connect 5 0 4 2; #X connect 6 0 4 1; #X connect 7 0 8 1; #X connect 8 0 4 0; #X connect 9 0 8 0; #X connect 11 0 12 0;
