Constructor Detail

PoolingLayer

public PoolingLayer(int filterSize,
                    int padSize,
                    int strideSize)

Constructs a pooling layer with parameters having identical width and height, a default MaxPoolNeuron, and a default MaxPoolLink.

Parameters:

filterSize - the width and height of the pool

padSize - the width and height of the pad

strideSize - the width and height of the stride

PoolingLayer

public PoolingLayer(int filterWidth,
                    int filterHeight,
                    int padWidth,
                    int padHeight,
                    int strideWidth,
                    int strideHeight,
                    Neuron neuron,
                    Link link)

Constructs a general pooling layer. Note that after construction the layer contains no neurons, as they are determined when connecting the layer.

Parameters:

filterWidth - the width of the pool

filterHeight - the height of the pool

padWidth - the width of the pad

padHeight - the height of the pad

strideWidth - the width of the stride

strideHeight - the height of the stride

neuron - the neuron type (if null, default MaxPoolNeuron)

link - the link type (if null, default MaxPoolLink)

Method Detail

addMap

public void addMap(PoolingMap map)

Adds a pooling map to this layer.

Parameters:

map - a pooling map

connect

public boolean connect(Layer layer)

Connects this layer with the given layer. The number of maps in this layer has to be determined here, as it depends on the layer to be connected. For each map/channel of the other layer a pooling map is cloned (if it is not there already) and connected.

Overrides:

connect in class Layer

Parameters:

layer - the previous layer

Returns:

true, if some connection has been made

toString

public java.lang.String toString()

Returns the width x height x depth of this layer.

Overrides:

toString in class Layer

Returns:

the string expression
