Merge by Product

Calculates the product of all input tensors.

nn_module

Calls nn_merge_prod() when trained.

Parameters

No parameters.

Input and Output Channels

One input channel called "input" and one output channel called "output". For an explanation see PipeOpTorch.

PipeOpTorchMerges has either a vararg input channel if the constructor argument innum is not set, or input channels "input1", ..., "input<innum>". There is one output channel "output". For an explanation see PipeOpTorch.

State

The state is the value calculated by the public method $shapes_out().

PipeOpTorchMergeProd$new()

Creates a new instance of this R6 class.

Usage

PipeOpTorchMergeProd$new(id = "nn_merge_prod", innum = 0, param_vals = list())

Arguments

id

(character(1))
Identifier of the resulting object.

innum

(integer(1))
The number of inputs. Default is 0 which means there is one vararg input channel.

param_vals

(list())
List of hyperparameter settings, overwriting the hyperparameter settings that would otherwise be set during construction.

---

PipeOpTorchMergeProd$clone()

The objects of this class are cloneable with this method.

Usage

PipeOpTorchMergeProd$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
