Usually the operation is performed in the filter/channel dimension. This can also be used after fully-connected layers to reduce number of features.

Arguments:

• inputs: Tensor input
• num_units: Specifies how many features will remain after maxout in the axis dimension (usually channel). This must be a factor of number of features.
• axis: The dimension where max pooling will be performed. Default is the last dimension.
• scope: Optional scope for variable_scope.

Returns:

A Tensor representing the results of the pooling operation.

Raises:

• ValueError: if num_units is not multiple of number of features.
