Purpose

  • Implement TransformScheme.randomize_modules for hadamard matrices using permutations

Prerequisites

Changes

  • Add a permutations cache to HadamardFactory, keyed on module and weight (each unique model + weight combination gets its own permutation)
  • Implement apply_permutation helper function
  • Modify tests to include testing schemes for which randomize_modules is True

Testing

  • Correctness and memory sharing tests continue to pass with new randomize_modules schemes
