where x is a time-series, w is a synergy, ci and ti indicate the amplitude and onset time at i-th activation. J(i) indicates the index of synergy at i-th activation.
The extraction code is implemented in timevarying.py.
Briefly, timevarying.extract() can be used for synergy extraction.
An example is implemented in example.py.
You can also implement extraction codes for your dataset by following example.py and timevarying.extract().
