Package topo :: Package transferfn :: Module optimized

Module optimized

Output functions (see basic.py) and projection-level output functions (see projfn.py) written in C to optimize performance.

Requires the weave package; without it unoptimized versions are used.

Classes

[hide private]

CFPOutputFn
Type for an object that applies some operation (typically something like normalization) to all CFs in a CFProjection for which the specified mask (typically the activity at the destination of this projection) is nonzero.

TransferFn
Function object to modify a matrix in place, e.g.

IdentityTF
Identity function, returning its argument as-is.

DivisiveNormalizeL1
TransferFn that divides an array by its L1 norm.

DivisiveNormalizeL1_opt
TransferFn that divides an array by its L1 norm.

CFPOF_DivisiveNormalizeL1_opt
Non-optimized version of CFPOF_DivisiveNormalizeL1_opt.

CFPOF_DivisiveNormalizeL1
Non-optimized version of CFPOF_DivisiveNormalizeL1_opt.
