espnet.utils.spec_augment.apply_interpolation(query_points, train_points, w, v, order)

Apply polyharmonic interpolation model to data.

Notes

Given coefficients w and v for the interpolation model, we evaluate interpolated function values at query_points.

• Parameters:
  • query_points – [b, m, d] x values to evaluate the interpolation at
  • train_points – [b, n, d] x values that act as the interpolation centers ( the c variables in the wikipedia article) w: [b, n, k] weights on each interpolation center v: [b, d, k] weights on each input dimension
  • order – order of the interpolation
• Returns: Polyharmonic interpolation evaluated at points defined in query_points.
