Line of code in question:
summing += yval * np.log( sigmoid(np.dot(w.transpose(),xi.transpose()))) +(1-yval)* np.log(max(0.001, 1-sigmoid(np.dot(w.transpose(),xi.transpose()))))
Error:
File "classify.py", line 67, in sigmoid return 1/(1+ math.exp(-gamma)) OverflowError: math range error
The sigmoid function is just 1/(1+ math.exp(-gamma))
.
I’m getting a math range error. Does anyone see why?
