Dual Dimensionality Reduction Reveals Independent Encoding of Motor Features in a Muscle Synergy for Insect Flight Control
Fig 4
Identified features support the independence model.
We plotted the timecourse (loadings) of each significant PLS feature (A). The decile-averaged score for each feature varied from one extreme of turning to the other (B). We determined how well different subsets of the timing variables (the independence, synergy, and redundancy models) predicted either the mean torque (C) or the feature scores (D, E) with a hold-one-out PRESS statistic. The box plots represent the mean and quartiles, with whiskers encompassing all non-outliers. Horizontal lines indicate statistically separate groups.
