WebLinear classifier. In this module we will start out with arguably the simplest possible function, a linear mapping: f ( x i, W, b) = W x i + b. In the above equation, we are assuming that the image x i has all of its pixels flattened out to a single column vector of shape [D x 1]. The matrix W (of size [K x D]), and the vector b (of size [K x 1 ...
