title: Binary classification with Softmax
body: <p>I am training a binary classifier using Sigmoid activation function with Binary crossentropy which gives good accuracy around 98%.<br>
  The same when I train using softmax with categorical_crossentropy gives very low accuracy (&lt; 40%).<br>
  I am passing the targets for binary_crossentropy as list of 0s and 1s eg; [0,1,1,1,0]. </p>
  
  <p>Any idea why this is happening?</p>
  
  <p>This is the model I am using for the second classifier:
