Package sheet

Sheet classes.

A Sheet is a two-dimensional arrangement of processing units, typically modeling a neural region or a subset of cells in a neural region. Any new Sheet classes added to this directory will automatically become available for any model.

ActivityCopy
Copies incoming Activity patterns to its activity matrix and output port.

CFSheet
A ProjectionSheet providing access to the ConnectionFields in its CFProjections.

GeneratorSheet
Sheet for generating a series of 2D patterns.

JointNormalizingCFSheet
A type of CFSheet extended to support joint sum-based normalization.

JointNormalizingCFSheet_Continuous
CFSheet that runs continuously, with no 'resting' periods between pattern presentations.

ProjectionSheet
A Sheet whose activity is computed using Projections from other sheets.

SequenceGeneratorSheet
Sheet that generates a timed sequence of patterns.

Sheet
The generic base class for neural sheets.
