Performance-based control interfaces using mixture of factor analyzers

The Visual Computer, 2011
This paper introduces an approach to performance animation that employs a small number of inertial measurement sensors to create an easy-to-use system for an interactive control of a full-body human character. Our key idea is to construct a global model from a prerecorded motion database and utilize them to construct full-body human motion in a maximum

Web User Segmentation Based on a Mixture of Factor Analyzers

2006
This paper proposes an approach for Web user segmentation and online behavior analysis based on a mixture of factor analyzers (MFA). In our proposed framework, we model users’ shared interests as a set of common latent factors extracted through factor analysis, and we discover user segments based on the posterior component distribution of a finite ...

Mixture of Factor Analyzers for the Clustering and Visualization of High-Dimensional Data

2019
The basic ideas underlying latent class analysis were developed by Paul Lazarsfeld in the previous century (Lazarsfeld, 1950, 1959; Lazarsfeld & Henry, 1968). The methods proposed by him and his coworkers for estimating the parameters of the latent class model were, although leading to best asymptotically normal (BAN) estimates, rather arbitrary and ...
