Classes [hide private]
  Sheet
The generic base class for neural sheets.
  ProjectionSheet
A Sheet whose activity is computed using Projections from other sheets.
  CFSheet
A ProjectionSheet providing access to the ConnectionFields in its CFProjections.
  ActivityCopy
Copies incoming Activity patterns to its activity matrix and output port.
  GeneratorSheet
Sheet for generating a series of 2D patterns.
  SequenceGeneratorSheet
Sheet that generates a timed sequence of 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.
Functions [hide private]
 
compute_joint_norm_totals(projlist, mask)
Compute norm_total for each CF in each projection from a group to be normalized jointly.
