- chainerx.dot(a, b)¶
Returns a dot product of two arrays.
For arrays with more than one axis, it computes the dot product along the last axis of
aand the second-to-last axis of
b. This is just a matrix product if the both arrays are 2-D. For 1-D arrays, it uses their unique axis as an axis to take dot product over.
- Return type
This function currently does not support N > 2 dimensional arrays.
During backpropagation, this function propagates the gradient of the output array to input arrays
