# sparse_connection_impl

Operates like a matrix (for multiplication) with a large number of `inhibition` values and a small number of `excitation` values. Notionally, for each dimension at the target layer, there is a small number of matching dimensions at the source layer, from which it receives excitation rather than inhibition.

## Parameters

    parameter	default_value
    excitation	1
    inhibition	0

## details

    some_spc details

Print a human-readable list of excitation mappings; each row represents a dimensions on the target layer representation, and lists the “matching” dimension numbers on the source layer representation.
