DynamicRookie Posted June 22, 2018 Share Posted June 22, 2018 Hey there! I'm trying to rebuild a python script in AU3, i've been wandering and trying to figure out how i could do it The .py script is this: expandcollapse popupimport numpy as np def nonlin(x,deriv=False): if(deriv==True): return x*(1-x) return 1/(1+np.exp(-x)) X = np.array([[0,0,1], [0,1,1], [1,0,1], [1,1,1]]) y = np.array([[0], [1], [1], [0]]) np.random.seed(1) # randomly initialize our weights with mean 0 syn0 = 2*np.random.random((3,4)) - 1 syn1 = 2*np.random.random((4,1)) - 1 for j in xrange(60000): # Feed forward through layers 0, 1, and 2 l0 = X l1 = nonlin(np.dot(l0,syn0)) l2 = nonlin(np.dot(l1,syn1)) # how much did we miss the target value? l2_error = y - l2 if (j% 10000) == 0: print "Error:" + str(np.mean(np.abs(l2_error))) # in what direction is the target value? # were we really sure? if so, don't change too much. l2_delta = l2_error*nonlin(l2,deriv=True) # how much did each l1 value contribute to the l2 error (according to the weights)? l1_error = l2_delta.dot(syn1.T) # in what direction is the target l1? # were we really sure? if so, don't change too much. l1_delta = l1_error * nonlin(l1,deriv=True) syn1 += l1.T.dot(l2_delta) syn0 += l0.T.dot(l1_delta) So far, i got this: expandcollapse popup_AutoItObject_Startup() $NN_Ins = FileOpen($Netfile) $IFRead = FileReadLine($NN_Ins, 1) $NRFlags = StringSplit($IFRead, '/') $NFlags[3] = [$NRFlags[1], _ $NRFlags[2], _ $NRFlags[3] ] Global $DSI[4][3] = [[0,0,1], [0,1,1], [1,0,1], [1,1,1]] Global $DSO[4] = [0, 1, 1, 0] Global $DTV = Vector() $DTV.Init($DSI, $DSO) $syn0 = 2*(Random(3,4) - 1) $syn1 = 2*(Random(1, 4) - 1) For $x In $DSI For $y in $DSO $l1 = 1/(1+Exp($DTV.Dot($x, $syn0)) $l2 = 1/(1+Exp($DTV.Dot($l1, $syn1)) $d0 = ($y - $l2)*($l2*(1-$l2)) $d1 ; i got lost Next Next Func Vector() Local $this = _AutoItObject_Create() _AutoItObject_AddMethod($this, "Dot", "Vector_DotProduct") Return $this EndFunc ;==>Vector Func Vector_DotProduct($this, $vector1 = '', $vector2 = '') Switch IsArray($vector1) And IsArray($vector2) Case 1 Switch UBound($vector1) >= 3 And UBound($vector1) >= 3 Case 1 Local $DotProduct[3] Case 0 EndSwitch Case 0 Return SetError(1, 0, -1) EndSwitch EndFunc ;==>Vector_DotProduct The purpose of the main script is simulating an artificial neural network with algebra. I'm lost on the part where i must declare $l1 and $l2 variables, the value is supposed to be the dotproduct of 2 variables, but i don't know how i can do that (I'm also horrible at algebra) I know about the "We help you to fix ur code, not code for you", but, honestly, i'm lost - i'm not good at python, neither on AutoIt, excuse me for it. Any help is really appreciated Thanks in advance Link to comment Share on other sites More sharing options...
