Crate numcodecs_random_projection

Random Projection codec implementation for the numcodecs API.

Structs

• ClosedOpenUnit
  Floating point number in [0.0, 1.0)
• OpenClosedUnit
  Floating point number in (0.0, 1.0]
• RandomProjectionCodec
  Codec that uses random projections to reduce the dimensionality of high- dimensional data to compress it.

Enums

• RandomProjectionCodecError
  Errors that may occur when applying the RandomProjectionCodec.
• RandomProjectionKind
  Projection kind that is used to generate the random projection matrix
• RandomProjectionReduction
  Method with which the reduced dimensionality K is selected

Traits

• FloatExt
  Floating point types.

Functions

• density_or_ping_li_minimum
  Extract the provided density if it is Some(_), or compute the minimum required density 1/sqrt(d) as recommended by Li et al .
• johnson_lindenstrauss_min_k
  Find a ‘safe’ number of components K to randomly project to.
• project_into
  Applies random projection to the input data and outputs into the projected array.
• project_with_projection
  Applies random projection to the input data with the given seed, reduction method, and projection kind and returns the resulting projected array.
• reconstruct
  Applies the (approximate) inverse of random projection to the projected array to reconstruct the input data with dimensionality d and returns the resulting reconstructed array.
• reconstruct_into
  Applies the (approximate) inverse of random projection to the projected array to reconstruct the input data outputs into the reconstructed array.
• reconstruct_into_with_projection
  Applies the (approximate) inverse of random projection to the projected array to reconstruct the input data with the given seed and projection kind and outputs into the reconstructed array.
• reconstruct_with_projection
  Applies the (approximate) inverse of random projection to the projected array to reconstruct the input data with the given seed and projection kind and returns the resulting reconstructed array.
