Detailed Description

A OneHot layer in a network definition.

The OneHot layer has three input tensors: Indices, Values, and Depth, one output tensor: Output, and an axis attribute.

  • Indices is an Int32 tensor that determines which locations in Output to set as on_value.
  • Values is a two-element (rank=1) tensor that consists of [off_value, on_value]
  • Depth is an Int32 shape tensor of rank 0, which contains the depth (number of classes) of the one-hot encoding. The depth tensor must be a build-time constant, and its value should be positive.
  • Output is a tensor with rank = rank(indices)+1, where the added dimension contains the one-hot encoding. The data types of Output is equal to the Values data type.
  • Axis is a scaler specifying to which dimension of the output one-hot encoding is added. Axis defaults to -1, that is the new dimension in the output is its final dimension. Valid range for axis is -rank(indices)-1 <= axis <= rank(indices).

The output is computed by copying off_values to all output elements, then setting on_value on the indices specified by the indices tensor. when axis = 0: output[indices[i, j, k], i, j, k] = on_value for all i, j, k and off_value otherwise.

when axis = -1: output[i, j, k, indices[i, j, k]] = on_value for all i, j, k and off_value otherwise.

Warning
Do not inherit from this class, as doing so will break forward-compatibility of the API and ABI.
