Machine learning for information retrieval

David Grangier

In this thesis, we explore the use of machine learning techniques for information retrieval. More specifically, we focus on ad-hoc retrieval, which is concerned with searching large corpora to identify the documents relevant to user queries. This identific ...

Object Category Detection using Audio-visual Cues

Barbara Caputo, Jie Luo

Categorization is one of the fundamental building blocks of cognitive systems. Object categorization has traditionally been addressed in the vision domain, even though cognitive agents are intrinsically multimodal. Indeed, biological systems combine severa ...

Computational models in the debate over language learnability

Frédéric Kaplan

Computational models have played a central role in the debate over language learnability. This article discusses how they have been used in different stances, from generative views to more recently introduced explanatory frameworks based on embodiment, cog ...

On-line Independent Support Vector Machines for Cognitive Systems

Barbara Caputo, Jie Luo

Learning from experience and adapting to changing stimuli are fundamental capabilities for artificial cognitive systems. This calls for on-line learning methods able to achieve high accuracy while at the same time using limited computer power. Research on ...

Tracking Attention for Multiple People: Wandering Visual Focus of Attention Estimation

Daniel Gatica-Perez, Jean-Marc Odobez, Silèye Oumar Ba, Kevin Smith

The problem of finding the visual focus of attention of multiple people free to move in an unconstrained manner is defined here as the {\em wandering visual focus of attention} (WVFOA) problem. Estimating the WVFOA for multiple unconstrained people is a ne ...

Service discovery, composition and execution for large scale open environments

Ion Constantinescu

In today's largest open environment, the World Wide Web, human-to-computer interactions are predominant. The natural evolution envisioned by many people is towards a Web in which the majority of interactions will be computer-to-computer. This has certain b ...

Autonomous virtual agents learning a cognitive model and evolving

Daniel Thalmann, Toni Conde

In this paper, we propose a new integration approach to simulate an autonomous virtual agent's cognitive learning of a task for interactive virtual environment applications. Our research focuses on the behavioural animation of virtual humans capable of act ...
