Web15 Nov 2024 · Copy a tensor setting everything outside a central band in each innermost matrix to zero. Summary The band part is computed as follows: Assume input has k dimensions [I, J, K, ..., M, N] , then the output is a tensor with the same shape where Webdef upper_triangular_to_array (A): N = A.shape [0] return np.array ( [p for i, p in enumerate (A.flatten ()) if i > (i / N) * (1 + N)]) This function requires that A is a 2-dimensional square numpy array to return the correct result. It also relies on floor division of integers, which you will need to correct for if you use python 3.x. The ... WebYou can use tf.matrix_band_part(input, 0, -1) to create an upper triangular matrix from a square one, so this code would allow you to train on n(n+1)/2 variables although it has you create n*n:.
