We consider model selection for non-linear dynamic equations with more candidate variables than observations, based on a general class of non-linear-in-the-variables functions, addressing possible location shifts by impulse-indicator saturation. After an automatic search delivers a simplified congruent terminal model, an encompassing test can be implemented against an investigator’s preferred n...

The present work describes a new method for modeling 3-D motion capture data of speech movements. 27 markers on the face of a speaker uttering 27 VCVs were tracked by a Vicon motion capture system. The 3-D coordinates of the markers in all frames of the recording were modeled in four ways: 1) a plain PCA, 2) a guided PCA where each component is determined on a subset of markers that represent a...
