Model Adaptation for Sentence Unit Segmentation from Speech

The sentence segmentation task is a classification task that aims at inserting sentence boundaries in a sequence of words. One of the applications of sentence segmentation is to detect the sentence boundaries in the sequence of words that is output by an a ...

Constructing visual models with a latent space approach

Daniel Gatica-Perez, Jean-Marc Odobez, Florent Monay Michaud, Pedro Manuel Da Silva Quelhas

We propose the use of latent space models applied to local invariant features for object classification. We investigate whether using latent space models enables to learn patterns of visual co-occurrence and if the learned visual models improve performance ...

Semi-supervised Adapted HMMs for Unusual Event Detection

Daniel Gatica-Perez, Samy Bengio, Dong Zhang

We address the problem of temporal unusual event detection. Unusual events are characterized by a number of features (rarity, unexpectedness, and relevance) that limit the application of traditional supervised model-based approaches. We propose a semi-supe ...

Role Composition in Requirements Engineering:the Method and Prototyping Tool

Alain Wegmann, Gleb Skobeltsyn, Pavel Balabko

Using multiple contexts improves model understandability and contributes to solving a scalability problem. In our work, we introduce a modeling method called Systemic Enterprise Architecture Methodology (SEAM) that considers systems to be designed in diffe ...

Evolution of Adaptive Synapses: Robots with Fast Adaptive Behavior in New Environments

Dario Floreano, Joseba Urzelai

This paper is concerned with adaptation capabilities of evolved neural controllers. We propose to evolve mechanisms for parameter self-organization instead of evolving the parameters themselves. The method consists of encoding a set of local adaptation rul ...

Towards Speaker Independent Continuous Speechreading

This paper describes recent speechreading experiments for a speaker independent continuous digit recognition task. Visual feature extraction is performed by a lip tracker which recovers information about the lip shape and information about the grey-level i ...

Field Susceptibility Of A Composite System - Application To Van-Der-Waals Dispersive Interactions Inside A Finite Line Of Physisorbed Atoms

Olivier Martin

The growing interest in the study of natural or artificial nanoscale structures stabilized by a corrugated surface calls for specific models adapted to the awkward symmetry of such systems. In this work the field susceptibility of a system composed of a fi ...
