Question

If the change in weight vector is represented by ∆wij, what does it mean?

(a) describes the change in weight vector for ith processing unit, taking input vector jth into account

(b) describes the change in weight vector for jth processing unit, taking input vector ith into account

(c) describes the change in weight vector for jth & ith processing unit.

(d) none of the mentioned

I have been asked this question in a job interview.

My question comes from Learning topic in chapter Basics of Artificial Neural Networks of Neural Networks

Answer 1

The correct answer is (a) describes the change in weight vector for ith processing unit, taking input vector jth into account

The explanation is: ∆wij= µf(wi a)aj, where a is the input vector.
