Thank you for the feedback,
I noticed that even then, this version of NCC is bugged. I will recode it.

Hi,
It should be fixed by now. The targets are -1,1 like other algorithms. Although I used a dirty trick of y = y/2 + .5

@Diviyan-Kalainathan I tried training this a number of times with different amounts of data. But I'm getting the same output for every input. After trying to debug I realised that it's output before the sigmoid layer is very close to 0 and due to the slope being very low there, the differences before the sigmoid layer(small) diminish. Can you please check it? Maybe the number of hidden layers in the model is less than what is required for a sizeable data.

Very strange... have you updated your package ?
Which kind of data are you using to train the model ? (remember to feed labels -1, +1) (If it's a public dataset, I'll be glad to take a look)
I am not able to reproduce this, in my case the model trains properly (on a simple dataset though)
There is a hyperparameter that you can modify to change the number of hidden units, but not for the number of layers ; try increasing the number of hidden units for now.
