tf.keras.ops.correlate

Compute the cross-correlation of two 1-dimensional tensors.

x1 First 1-dimensional input tensor of length M.
x2 Second 1-dimensional input tensor of length N.
mode Either valid, same or full. By default the mode is set to valid, which returns an output of length max(M, N) - min(M, N) + 1. same returns an output of length max(M, N). full mode returns the convolution at each point of overlap, with an output length of N+M-1

Output tensor, cross-correlation of x1 and x2.
