This file implements the major classes and functions for
making artificial neural networks in Python. Part of the
Pyrobot project.
Classes
Connection Class which contains references to two layers (from and to) and the weights between them.
Layer Class which contains arrays of node elements (ie, activation, error, bias, etc).
Network Class which contains all of the parameters and methods needed to run a neural network.
SRN A subclass of Network.

Exceptions
LayerError Used to indicate that a layer has some improper attribute (size, type, etc.).
NetworkError Used to indicate that a network has some improper attribute (no layers, no connections, etc.).
SRNError Used to indicate that SRN specific attributes are improper.

Function Summary
  displayArray(name, a, width)
Prints an array (any sequence of floats, really) to the screen.
  loadNetworkFromFile(filename)
Loads network from a file using pickle.
  ndim(n, *args)
Makes a multi-dimensional array of random floats.
  randomArray(size, bound)
Returns an array initialized to random values between -max and max.
  toStringArray(name, a, width)
Returns an array (any sequence of floats, really) as a string.
  writeArray(fp, a, delim, nl)
Writes a sequence a of floats to file pointed to by file pointer.

Variable Summary
str __author__ = 'Douglas Blank <dblank@brynmawr.edu>'
str __version__ = '$Revision: 1.153 $'

Function Details

displayArray(name, a, width=0) 

Prints an array (any sequence of floats, really) to the screen.

loadNetworkFromFile(filename) 

Loads network from a file using pickle. See Network.saveNetworkToFile()

ndim(n, *args) 

Makes a multi-dimensional array of random floats. (Replaces RandomArray).

randomArray(size, bound) 

Returns an array initialized to random values between -max and max.

toStringArray(name, a, width=0) 

Returns an array (any sequence of floats, really) as a string.

writeArray(fp, a, delim=' ', nl=1) 

Writes a sequence a of floats to file pointed to by file pointer.

Variable Details

__author__

Type:
str
Value:
'Douglas Blank <dblank@brynmawr.edu>'

__version__

Type:
str
Value:
'$Revision: 1.153 $'
