Posteriors in Limited Time

Robust Real-Time Visual Tracking Using Pixel-Wise Posteriors

We derive a probabilistic framework for robust, real-time, visual tracking of previously unseen objects from a moving camera. The tracking problem is handled using a bag-of-pixels representation and comprises a rigid registration between frames, a segmentation and online appearance learning. The registration compensates for rigid motion, segmentation models any residual shape deformation and th...

Teachers’ Limited Wait-Time Practice and Learners’ Participation opportunities in EFL Classroom Interaction

Pairing theory with methodology, this study demonstrates how EFL teachers’ limited wait-time practice structures in and affects the structuring of the unfolding classroom discourse with reference to learners’ participation opportunities. Informed by the tenets of conversation analysis, we have observed, videotaped, and transcribed line-by-line 10 EFL teachers’ naturally-occurring classroom inte...

Time Limited Model Checking

In this paper we present an approach to model concurrent systems specified in a temporal concurrent constraint language, which is able to model Hybrid Systems. We construct a framework in which it is possible to apply the Model Checking technique to programs specified in such language. We present a formalism to transform correctly specification into a Hybrid cc Structure. This structure represe...

Steering Time-Dependent Estimation of Posteriors with Hyperparameter Indexing in Bayesian Topic Models

This paper provides a new approach to topical trend analysis. Our aim is to improve the generalization power of latent Dirichlet allocation (LDA) by using document timestamps. Many previous works model topical trends by making latent topic distributions timedependent. We propose a straightforward approach by preparing a different word multinomial distribution for each time point. Since this app...
