Function

This Step is used to decompose a high-dimensional data list and merge the sub-lists in it.

Usage Scenario

This is a general-purpose Step for reducing data dimensionality. It can decompose a data list and then merge the extracted elements, and is commonly used for flattening high-dimensional data.

For example, if the input is \[[5], [6], [7]], the output can be [5, 6, 7].

Parameter Description

Parameter	Description
Operation Layer	Parameter description: This parameter specifies at which layer the “unpack and merge” operation is performed. Default value: 0 How to adjust: The behavior at each operation layer is described below. Default value: 0 Instruction: The operation layers are described as follows. If the Operation Layer parameter is set to 0, expand the sub-list of the outermost layers. For example, input [[1, 2]], [3, 4]] and output [1, 2, 3, 4]. If the Operation Layer parameter is set to 1: Operate the second layer, expand the sub-list in the second layer. For example, input [[[1, 2]], [3, 4]], [[5, 6]]], and output [[1, 2, 3, 4]], [5, 6]].

Parameter

Description

Operation Layer

Parameter description: This parameter specifies at which layer the “unpack and merge” operation is performed. Default value: 0 How to adjust: The behavior at each operation layer is described below.

Default value: 0

Instruction: The operation layers are described as follows.

If the Operation Layer parameter is set to 0, expand the sub-list of the outermost layers. For example, input [[1, 2]], [3, 4]] and output [1, 2, 3, 4].
If the Operation Layer parameter is set to 1: Operate the second layer, expand the sub-list in the second layer. For example, input [[[1, 2]], [3, 4]], [[5, 6]]], and output [[1, 2, 3, 4]], [5, 6]].
