Question 1: Short answer

easyAI-checkedConvolutional Neural Networks

A layer multiplies a 256-dimensional channel vector by a dense 256×256256 \times 256 weight matrix. You replace it with a block-diagonal matrix of 8 blocks of size 32×3232 \times 32, as a grouped convolution with 8 groups does. By what factor does the number of multiplications drop?

a whole number
