Efficient Dimension Reduction Of Global Signature With Sparse Projectors For Image Near Duplicate Retrieval
In this paper, we tackle the storage and computa- tional cost of linear projections used in dimensionality reduction for near duplicate image retrieval. We propose a new method based on metric learning with a lower training cost than existing methods. Moreover, by adding a sparsity constraint, we obtain a projection matrix with a low storage and projection cost. [...]
A context based decision making architecture for a navigation task
Corrective learning is an interesting paradigm for on-line learning of a trajectory from non-verbal interaction. We propose a model of action selection based on corrective interactions between the robot and a teacher. By using the appropriate correction signal, a minimal solution is to learn specific contexts inhibiting the wrong actions in order to let the appropriate behavior be exhibited in any circumstances.

Cooperation of S-R habit and cognitive learnings in goal-oriented navigation
The Stimulus-Response (S-R) theory and Tolman's Cognitive Theory of behavior control both issued from behaviorism in the early XXth century still provide a relevant general framework to account for animal rewardbased adaptive behavior. In this paper, we propose a new paradigm for representing and implementing both the cognitive strategy and the S-R habit strategy within a unitary coding frame. [...]
