[object Object]

[object Object][object Object]undefined[object Object]

• Function: performs segmentation and computation. Generates a semi-separable matrix with the diagonal being 0 and the upper triangle being -inf.

• Formula (using 4D input as an example):

  1. Reshape [object Object] from (N1, N2, N3, N4) to (N1, N2, N3, N4, 1).

  2. Perform broadcasting obtain (N1, N2, N3, N4, N4).

  3. Generate a BOOL triangular matrix A of shape (N4, N4), where the upper triangle is [object Object], the lower triangle is [object Object], and the diagonal is [object Object].

  4. Fill the elements in [object Object] with [object Object] at the positions where the corresponding elements in matrix A are [object Object].

     $$self_i= \begin{cases}self_i,\quad A_i==False \\0, \quad A_i==True \end{cases}$$

  5. Perform a cumulative sum along the second-to-last dimension of [object Object]. For an element from a dimensional perspective, other dimension indices remain unchanged while the current index increases. $selfTemp\_{i}$ is the element at the corresponding position in the output tensor.

     $$selfTemp_{i} = self_{1} + self_{2} + self_{3} + ...... + self_{i}$$

  6. Generate a BOOL triangular matrix B of shape (N4, N4), where the upper triangle is [object Object], the lower triangle is [object Object], and the diagonal is [object Object].

  7. Fill the elements in [object Object] with [object Object] at the positions where the corresponding elements in matrix B are [object Object].

     $$out_i= \begin{cases}selfTemp_i,\quad B_i==False \\-inf, \quad B_i==True \end{cases}$$

  8. Compute the exponent of each element in [object Object].

     $$out_i=e^{selfTemp_i}$$

Each operator has calls. First, [object Object] is called to obtain the workspace size required for computation and the executor that contains the operator computation process. Then, [object Object] is called to perform computation.
