OPtions as REsponses: Grounding behavioural hierarchies in multi-agent reinforcement learning

no code implementations ICML 2020 Alexander Vezhnevets, Yuhuai Wu, Maria Eckstein, Rémi Leblond, Joel Z. Leibo

This paper investigates generalisation in multi-agent games, where the generality of the agent can be evaluated by playing against opponents it hasn't seen during training.

Context Forest for efficient object detection with large mixture models

no code implementations3 Mar 2015 Davide Modolo, Alexander Vezhnevets, Vittorio Ferrari

We present Context Forest (ConF), a technique for predicting properties of the objects in an image based on its global appearance.

Joint calibration of Ensemble of Exemplar SVMs

no code implementations CVPR 2015 Davide Modolo, Alexander Vezhnevets, Olga Russakovsky, Vittorio Ferrari

We formulate joint calibration as a constrained optimization problem and devise an efficient optimization algorithm to find its global optimum.

An active search strategy for efficient object class detection

no code implementations CVPR 2015 Abel Gonzalez-Garcia, Alexander Vezhnevets, Vittorio Ferrari

First, we exploit context as the statistical relation between the appearance of a window and its location relative to the object, as observed in the training set.

Associative embeddings for large-scale knowledge transfer with self-assessment

no code implementations CVPR 2014 Alexander Vezhnevets, Vittorio Ferrari

By transferring knowledge from the images that have bounding-box annotations to the others, our method is capable of automatically populating ImageNet with many more bounding-boxes and even pixel-level segmentations.
