Constructor & Destructor Documentation

ANNLayering (  const char *    description = NULL )  [inline]

Standard constructor. See make for info about the parameters. Definition at line 78 of file topology.h. References make().

Member Function Documentation

void empty (    )  [inline]

Clears the layering; makes the network description empty. Reimplemented in LayeredTopology. Definition at line 119 of file topology.h. Referenced by LayeredTopology::empty().

void getPos (  int    i, int &    layerno, int &    layerpos )  const

Calculates the relative layer and offset for given absolute unit index. Parameters: i  Neuron index. layerno  Reference-returned result: layer index where the neuron resides. layerpos  Reference-returned result: position of the neuron on the layer indicated by the layerno result parameter. Definition at line 99 of file topology.cc. Referenced by ANNetwork::cleanup(), and ANNetwork::connectFfw().

int layerIndex (  int    layer )  const

Calculates the absolute neuron index offset for the given layer index; index of the first neuron on that layer. If the given layer index is negative, it is substracted from the number of layers (-1 means the output layer, -2 the layer below that, etc). Definition at line 75 of file topology.cc. Referenced by ANNetwork::connectFfw(), ANNetwork::connectFullFfw(), ANNetwork::drawFeedForward(), and totalUnits().

int layers (    )  const [inline]

Returns the number of layers in the network. Definition at line 90 of file topology.h. Referenced by ANNetwork::connectFullFfw(), ANNetwork::drawEPS(), ANNetwork::drawFeedForward(), and toString().

int layerSize (  int    i )  const [inline]

Returns the size of the layer i. Const version. If the given layer index is negative, it is substracted from the number of layers (-1 means the output layer, -2 the layer below that, etc). Definition at line 99 of file topology.h.

void make (  const char *    description )

Sets the layer structure according to the given description string. Parameters: description  Textual layer description. Consists of layer sizes separated by '-'-marks. For example: "2-10-10-1". NOTE: The layer sizes may currently NOT have additional qualifiers that are not numbers, for example: "S2-10-10-L10". These qualifiers are usually intended for the AnyNetwork inheritor, and should ignored here, but, as said, are currently not. Definition at line 54 of file topology.cc. Referenced by ANNLayering(), ANNetwork::drawFeedForward(), and LayeredTopology::LayeredTopology().

void operator= (  const ANNLayering &    o )  [inline]

Standard copy operator. Definition at line 122 of file topology.h. References mLayers.

int& operator[] (  int    i )  [inline]

Returns the size of the layer i. Non-const version. If the given layer index is negative, it is substracted from the number of layers (-1 means the output layer, -2 the layer below that, etc). Definition at line 115 of file topology.h.

int operator[] (  int    i )  const [inline]

Returns the size of the layer i. Const version. If the given layer index is negative, it is substracted from the number of layers (-1 means the output layer, -2 the layer below that, etc). Definition at line 107 of file topology.h.

void removeLayer (  int    i )  [inline]

Removes a layer. NOTE: The negative indexing is not allowed here. Definition at line 127 of file topology.h. Referenced by ANNetwork::cleanup().

String toString (    )  const

Converts the layering back to layering description string. Definition at line 108 of file topology.cc. References layers().

int totalUnits (    )  const [inline]

Returns the total number of units in the network. Definition at line 86 of file topology.h. References layerIndex().
