Mind-to-Image: Projecting Visual Mental Imagination of the Brain from fMRI

no code implementations8 Apr 2024 Hugo Caselles-Dupré, Charles Mellerio, Paul Hérent, Alizée Lopez-Persem, Benoit Béranger, Mathieu Soularue, Pierre Fautrel, Gauthier Vernier, Matthieu Cord

The reconstruction of images observed by subjects from fMRI data collected during visual stimuli has made significant strides in the past decade, thanks to the availability of extensive fMRI datasets and advancements in generative models for image generation.

Utility-based Adaptive Teaching Strategies using Bayesian Theory of Mind

1 code implementation29 Sep 2023 Clémence Grislain, Hugo Caselles-Dupré, Olivier Sigaud, Mohamed Chetouani

To this end, human teachers seem to build mental models of the learner's internal state, a capacity known as Theory of Mind (ToM).

Enhancing Agent Communication and Learning through Action and Language

no code implementations18 Aug 2023 Hugo Caselles-Dupré, Olivier Sigaud, Mohamed Chetouani

We introduce a novel category of GC-agents capable of functioning as both teachers and learners.

Pragmatically Learning from Pedagogical Demonstrations in Multi-Goal Environments

1 code implementation9 Jun 2022 Hugo Caselles-Dupré, Olivier Sigaud, Mohamed Chetouani

In this paper, we implement pedagogy and pragmatism mechanisms by leveraging a Bayesian model of Goal Inference from demonstrations (BGI).

Pedagogical Demonstrations and Pragmatic Learning in Artificial Tutor-Learner Interactions

no code implementations28 Feb 2022 Hugo Caselles-Dupré, Mohamed Chetouani, Olivier Sigaud

When demonstrating a task, human tutors pedagogically modify their behavior by either "showing" the task rather than just "doing" it (exaggerating on relevant parts of the demonstration) or by giving demonstrations that best disambiguate the communicated goal.

Are standard Object Segmentation models sufficient for Learning Affordance Segmentation?

no code implementations5 Jul 2021 Hugo Caselles-Dupré, Michael Garcia-Ortiz, David Filliat

We conclude that the problem of supervised affordance segmentation is included in the problem of object segmentation and argue that better benchmarks for affordance learning should include action capacities.

Towards Teachable Autotelic Agents

no code implementations25 May 2021 Olivier Sigaud, Ahmed Akakzia, Hugo Caselles-Dupré, Cédric Colas, Pierre-Yves Oudeyer, Mohamed Chetouani

In the field of Artificial Intelligence, these extremes respectively map to autonomous agents learning from their own signals and interactive learning agents fully taught by their teachers.

On the Sensory Commutativity of Action Sequences for Embodied Agents

no code implementations13 Feb 2020 Hugo Caselles-Dupré, Michael Garcia-Ortiz, David Filliat

In such case, for autonomous embodied agents with first-person sensors, perception can be learned end-to-end to solve particular tasks.

DisCoRL: Continual Reinforcement Learning via Policy Distillation

no code implementations11 Jul 2019 René Traoré, Hugo Caselles-Dupré, Timothée Lesort, Te Sun, Guanghang Cai, Natalia Díaz-Rodríguez, David Filliat

In multi-task reinforcement learning there are two main challenges: at training time, the ability to learn different policies with a single model; at test time, inferring which of those policies applying without an external signal.

Symmetry-Based Disentangled Representation Learning requires Interaction with Environments

1 code implementation NeurIPS 2019 Hugo Caselles-Dupré, Michael Garcia-Ortiz, David Filliat

Finding a generally accepted formal definition of a disentangled representation in the context of an agent behaving in an environment is an important challenge towards the construction of data-efficient autonomous agents.

S-TRIGGER: Continual State Representation Learning via Self-Triggered Generative Replay

no code implementations25 Feb 2019 Hugo Caselles-Dupré, Michael Garcia-Ortiz, David Filliat

As the environment changes, the aim is to efficiently compress the sensory state's information without losing past knowledge, and then use Reinforcement Learning on the resulting features for efficient policy learning.

Word2Vec applied to Recommendation: Hyperparameters Matter

1 code implementation11 Apr 2018 Hugo Caselles-Dupré, Florian Lesaint, Jimena Royo-Letelier

Skip-gram with negative sampling, a popular variant of Word2vec originally designed and tuned to create word embeddings for Natural Language Processing, has been used to create item embeddings with successful applications in recommendation.
