Copy delayed version of the input signal on the space dimensions. For example, for ``time_frames=3`` and ``gap=2``:: [ X(1) Y(1) [ X(1) Y(1) 0 0 0 0 X(2) Y(2) X(2) Y(2) 0 0 0 0 X(3) Y(3) --> X(3) Y(3) X(1) Y(1) 0 0 X(4) Y(4) X(4) Y(4) X(2) Y(2) 0 0 X(5) Y(5) X(5) Y(5) X(3) Y(3) X(1) Y(1) X(6) Y(6) ... ... ... ... ... ... ] X(7) Y(7) X(8) Y(8) ... ... ] This node provides similar functionality as the ``TimeFramesNode``, only that it performs a time embedding into the past rather than into the future. See ``TimeDelaySlidingWindowNode`` for a sliding window delay node for application in a non-batch manner. Original code contributed by Sebastian Hoefer. Dec 31, 2010

|
Process the data contained in `x`. If the object is still in the training phase, the function `stop_training` will be called. `x` is a matrix having different variables on different columns and observations on the rows. By default, subclasses should overwrite `_execute` to implement their execution phase. The docstring of the `_execute` method overwrites this docstring.
|
This function returns a pseudo-inverse of the execute frame. y == execute(x) only if y belongs to the domain of execute and has been computed with a sufficently large x. If gap > 1 some of the last rows will be filled with zeros.
