Data Acquisition, Registration and Modelling for Multi-dimensional Functional Data
The clustering and classification for functional data with misaligned problems has drawn much attention in the last decade. Most methods do the clustering/classification after those functional data being registered and there has been little research using both functional and scalar variables. In this talk, I will first review some commonly used tools for data registration, followed by discussing a new approach allowing simultaneous registration and clustering/classification and also allowing both types of variables. Numerical results based on both simulated data and real data will be presented.
