An overview is provided of recent developments in the use of latent class (LC) and other types of %nite mixture models for classi%cation purposes. Several extensions of existing models are presented. Two basic types of LC models for classi%cation are de%ned: supervised and unsupervised structures. Their most important special cases are presented and illustrated with an empirical example. c © 20...

Humans have the fascinating capacity to understand, and anticipate the actions of other humans in the same space, without requiring verbal communication. This ”intention reading” capacity is underpinned by a common motor-repertoire that is shared by all humans, and afforded by a subtle coordination of eye-head-arm movements that encodes the cues and signals that will ultimately be deciphered by...

Colour cues were used to obtain robust detection and tracking of people in relatively unconstrained dynamic scenes. Gaussian mixture models were used to estimate probability densities of colour for skin, clothing and background. These models were used to detect, track and segment people, faces and hands. A technique for dynamically updating the models to accommodate changes in apparent colour d...

This paper proposes a general class of regression models for continuous proportions when the data contain zeros or ones. The proposed class of models assumes that the response variable has a mixed continuous-discrete distribution with probability mass at zero or one. The beta distribution is used to describe the continuous component of the model, since its density has a wide range of different ...

This paper presents a two-step method for eliminating the shadows of moving targets. As the first step, we improve the Gaussian mixture model for obtaining a real-time background and a moving foreground; secondly, we figure out the intersection of background difference and moving foreground for eliminating the concomitant shadow [1-5]. Experiment results indicate that our method has a preferabl...

One point of debate in the recent controversy in the media and among policy analysts over the academic achievement of charter school students is whether the charter students are in some way harder to educate than their counterparts enrolled in traditional public schools. In this paper we examine this question using data from the 2002-3 school year in Washington, D.C. We begin by examining a sim...
