qfeval_functions.functions.project

project(a, x)

Projects the given tensor x using the given projection matrix a.

Parameters:

• a (Tensor) – A projection matrix.

• x (Tensor) – A tensor to be projected.

Returns:

The projected tensor.

Return type:

Tensor

Shape:

• a: \((*, O, I)\), where \(*\) represents any number of

  dimensions (including None), \(O\) is the number of output dimensions, and \(I\) is the number of input dimensions.

• x: \((*, S, I)\), where \(*\) represents any number of

  dimensions (including None), \(S\) is the number of sections, and \(I\) is the number of input dimensions.

• return: \((*, S, O)\), where \(*\) represents any number of

  dimensions (including None), \(S\) is the number of sections, and \(O\) is the number of output dimensions.

In qfeval, I/O dimensions and sections often represent symbols and timestamps respectively.
