Consider the
as the weight matrix between the input layer
and 1st hidden layer
in a feedforward NN. Note that
does not include the bias
, and we can write
.
There are 15 neurons in the input layer, i.e.
is a column vector with 15 elements, and 11 neurons in the 1st hidden layer.
How many rows does the weight matrix
have?
