analyze-archive - generate PTA energy model from dfatool benchmark traces
analyze-archive generates a PTA energy model from one or more annotated
traces generated by dfatool. By default, it does nothing else.
Cross-Validation help:
If <method> is "montecarlo": Randomly divide data into 2/3 training and 1/3
validation, <count> times. Reported model quality is the average of all
validation runs. Data is partitioned without regard for parameter values,
so a specific parameter combination may be present in both training and
validation sets or just one of them.
If <method> is "kfold": Perform k-fold cross validation with k=<count>.
Divide data into 1-1/k training and 1/k validation, <count> times.
In the first set, items 0, k, 2k, ... ard used for validation, in the
second set, items 1, k+1, 2k+1, ... and so on.
validation, <count> times. Reported model quality is the average of all
validation runs. Data is partitioned without regard for parameter values,
so a specific parameter combination may be present in both training and
validation sets or just one of them.
Trace Export:
Each JSON file lists all occurences of the corresponding state/transition in the
benchmark's PTA trace. Each occurence contains the corresponding PTA
parameters (if any) in 'parameter' and measurement results in 'offline'.
As measurements are typically run repeatedly, 'offline' is in turn a list
of measurements: offline[0]['uW'] is the power trace of the first
measurement of this state/transition, offline[1]['uW'] corresponds t the
second measurement, etc. Values are provided in microwatts.
For example, TX.json[0].offline[0].uW corresponds to the first measurement
of the first TX state in the benchmark, and TX.json[5].offline[2].uW
corresponds to the third measurement of the sixth TX state in the benchmark.
WARNING: Several GB of RAM and disk space are required for complex measurements.
(JSON files may grow very large -- we trade efficiency for easy handling)
