Neural Network Intercept Bias

Closed this issue · 1 comments

I am going through a NN tutorial from this website

I am confused about one particular paragraph in this page (screenshot below).

enter image description here

  1. Is the choice of the intercept bias of -1 purely arbitrary? I don't quite understand his explanation.

  2. It said in the screenshot that the RBF function maps all values to a range of [0, +infinity]. However, the RBF function only maps to a range of [0,1]. Is this a mistake? And how does this positive range lead to a choice of -1 intercept bias?
