More explanations:
The negative number means to pad contextStart time-steps of zeros or learnable parameters at the beginning of each instance. The positive number means to skip contextStart time-steps of each instance.

I think this is an argument the users must set, so please do not set the default value.

From the realization of function, using StridedCopy in context_project is also appropriate. But from the efficiency analysis, the efficiency of using StridedCopy is not high. |
