Dropout: Each neuron is dropped independently.

Returns the inverse of a matrix using LU-decomposition.

permute() orders the rows of A to match the integers in the index array.

Perform Projection. joints: N * 3

calculate savitzky golay coefficients.

angle_axis is a 3d vector whose direction points to the rotation axis and whose norm is the angle (in radians)

This function computes the rotation matrix corresponding to Euler Angle (x, y, z) R_z * R_y * R_x (consistent with Ceres). (x, y, z) in degrees.

Returns end point error for one keypoint.

Returns pck for one keypoint for the given threshold.
