How weight vector behave when we initialize the weight to 0 in case of perceptron
While reading in book i encountered this statement
Now, the reason we don't initialize the weights to zero is that the learning rate (eta) only has an effect on the classification outcome if the ...

Why my neural network model is not able to learn a simple linear function?
I'm trying, using a neural network, to predict a simple relation $ f(x) = 1-x $.
I write my function this way: $f(x) = 1 - x^{+} + (-x)^{+} $ or in a more data-scientistic way: $f(x)= 1-Relu(x)+Relu(-...
