All Implemented Interfaces:

Serializable, Cloneable, TrainingConfig

public class Upsampling1D
extends BaseUpsamplingLayer

Upsampling 1D layer
Repeats each step size times along the temporal/sequence axis (dimension 2)
For input shape [minibatch, channels, sequenceLength] output has shape [minibatch, channels, size * sequenceLength]
Example:

 If input (for a single example, with channels down page, and sequence from left to right) is:
 [ A1, A2, A3]
 [ B1, B2, B3]
 Then output with size = 2 is:
 [ A1, A1, A2, A2, A3, A3]
 [ B1, B1, B2, B2, B3, B2]

getOutputType

public InputType getOutputType(int layerIndex,
                               InputType inputType)

Description copied from class: Layer

For a given type of input to this layer, what is the type of the output?

Specified by:

getOutputType in class Layer

Parameters:

layerIndex - Index of the layer

inputType - Type of input for the layer

Returns:

Type of output from the layer

getPreProcessorForInputType

public InputPreProcessor getPreProcessorForInputType(InputType inputType)

Description copied from class: Layer

For the given type of input to this layer, what preprocessor (if any) is required?
Returns null if no preprocessor is required, otherwise returns an appropriate InputPreProcessor for this layer, such as a CnnToFeedForwardPreProcessor

Overrides:

getPreProcessorForInputType in class BaseUpsamplingLayer

Parameters:

public LayerMemoryReport getMemoryReport(InputType inputType)

Description copied from class: Layer

This is a report of the estimated memory consumption for the given layer

Specified by:

getMemoryReport in class Layer

Parameters:

inputType - Input type to the layer. Memory consumption is often a function of the input type

Returns:

Memory report for the layer
