Default Re: Doubt on weights and pla

Thanks for the idea about the bias it was really helpful! ... i tried a simple case for understanding better...

The PLA ran indefinitely because of the absence of bias (bias = 0 because of the target function i was having in my mind)
The problem was the random training points i generated based on the expected target function had a bit of a flaw that some points were present on the target function and not on either of its sides...further bias of 0 caused the PLA to generate lines that rotated about the origin alone..this at times prevented the algorithm to get to a solution and ran indefinitely!
