Concept understanding problem

#1

i video at 6:11 , should’nt the shape of the matrix be (4 X n) instead of (n X 4) as there are n features of each example?

Hey @saksham_thukral, the previous layer is input layer, which will pass matrix (m,n) to this layer. Now if this layer has shape of (4,n) than we can’t do direct matrix multiplication, but it could be done when shape is of(n,4).

Hope this resolved your doubt.
Plz mark the doubt as resolved in my doubts section. :blush:
