Question

what are affine transformations?

(a) addition of bias term (-1) which results in arbitrary rotation, scaling, translation of input pattern.

(b) addition of bias term (+1) which results in arbitrary rotation, scaling, translation of input pattern.

(c) addition of bias term (-1) or (+1) which results in arbitrary rotation, scaling, translation of input pattern.

(d) none of the mentioned

I have been asked this question during an interview.

Query is from Determination of Weights topic in division Feedforward Neural Networks of Neural Networks

Answer 1

Correct answer is (a) addition of bias term (-1) which results in arbitrary rotation, scaling, translation of input pattern.

The best I can explain: It follows from basic definition of affine transformation.
