Torch Entry Point for Numeric Features

Source: R/PipeOpTorchIngress.R
mlr_pipeops_torch_ingress_num.Rd

Ingress PipeOp that represents a numeric (integer() and numeric()) entry point to a torch network.

Internals

Uses batchgetter_num().

Input and Output Channels

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

State

The state is set to the input shape.
