2021-02-12PELT: use variable penalty for benchmark repetationsDaniel Friesel-40/+64
Previously, the first measurement of each by_param entry determined its penalty, and all subsequenc measurements in it were analyzed with this penalty. This lead to some of them coming up with a different number of sub-states and being ignored. Now, all by_param entries are passed to the kneedle / plateau algorithm, and each gets its own penalty. In most cases, this leads to all entries rporting the same number of sub-states, so far less need to be ignored.

2021-01-14EnergyTrace drift compensation: optimize via shortest pathsDaniel Friesel-72/+88
Right now performance is worse than the previous greedy approach as the dijkstra variant does not take into account that a transition may be missing from the set of detected changepoints (i.e., it assumes that the set of detected changepoints contains the transition timestamp, which is not always the case). This will be fixed in the next commit by adding nodes for the expected transition timestamp (with a slightly higher weight to ensure there are no proper nodes in the vicinity) -- or something similar.

Enable with DFATOOL_COMPENSATE_DRIFT=1 so far it's pretty unreliable.

this also fixes a nasty off-by-one in the barcode loader (now _load_energytrace): wrong: interval_start_timestamp = data[:-1, 0] * 1e-6 correct: interval_start_timestamp = data[1:, 0] * 1e-6
