-#X text 51 84 for better performances inputs value should be normalized

-\, all input should have the same range (if one input has a larger

-range it will be more "important"). the range of each input should

-be 0 centered. so [-1 \, 1] is good [-2 \, 2] is good \, [0 \, 1] not

-so good [1 \, 2] is bad. the range sould not be too small ([-0.1 \,

-0.1] is bad).;
