chainerx.dot¶
- 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
a
and the second-to-last axis ofb
. 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.- Parameters
- Returns
Output array.
- Return type
Note
This function currently does not support N > 2 dimensional arrays.
Note
During backpropagation, this function propagates the gradient of the output array to input arrays
a
andb
