Select the number of tensor synergies by a VAF threshold — muscleSynergyTensorOrder • PhysioEMG

Fits non-negative PARAFAC for increasing rank and returns the smallest number of synergies whose reconstruction VAF reaches vaf_threshold.

Usage

muscleSynergyTensorOrder(tensor, max_synergies = 6, vaf_threshold = 0.9, ...)

Arguments

tensor: A non-negative muscle x time x trial array.
max_synergies: Largest rank to try (default 6).
vaf_threshold: VAF target (default 0.90).
...: Passed to muscleSynergyTensor().

Value

A list with n_synergies (selected), vaf (per rank), and fit (the selected "synergy_tensor").
