OK - brain now engaged:
Mask[t][k] = (Basis[k] * Activation[t]) / Sum(Bases[c][k] * Activations[c][k])
where c is the component (t and k more obviously are time and bins) and the summing is for all c.
Is that right?
Also - am I correct that these masks are totally page for other objects like the HPSS? I’m interested in both being able to analyses them, and potentially process and then apply them, but right now it feels like that isn’t very possible with the tools as they are - have I missed something?
