MSc Internship - Evolving Reservoir Meta-RL - Inria, Bordeaux, France
by Xavier Hinaut Dec. 1, 2023

Dec. 1, 2023

Please find below an offer for an intership from February/March to July/August 2024 in Mnemosyne team at Inria, Bordeaux, France # Title Title: Evolving Reservoirs for Meta Reinforcement Learning # Supervision Xavier Hinaut, Mnemosyne team, Inria Bordeaux Potential collaboration with Clément Moulin-Frier (Flowers Team) & Pierrick Legrand (Astral Team) # Duration: 6 months, spring/summer 2024. Level: Master 2 research internship # Keywords: meta reinforcement learning, reservoir computing, evolutionary computation, neuroevolution, simulation environments, scientific programming with Python. # Research team & internship location Mnémosyne Team: Inria Bordeaux Sud-Ouest, LABRI & Institut des Maladies Neurodégénératives (Centre Broca Aquitaine, Carreire campus) https://team.inria.fr/mnemosyne # Project How can a reinforcement learning (RL) agent autonomously learn a diversity of skills with minimal external supervision? Recent works have shown that a single goal-conditioned policy can be trained to solve multiple tasks in parallel (see e.g. Colas et al., 2021 for a recent review). Other works in Meta Reinforcement Learning (Meta-RL) have shown that artificial agents can “learn how to learn” (hence the term meta-learning) multiple skills without having access to goal-related information (see e.g. Weng, 2019 for an introduction). Meta-RL aims at equipping agents with the ability to generalize to tasks or environments that have not been encountered during training. Two nested processes of adaptation are traditionally considered: an outer adaptation loop optimizing the hyperparameters of an inner adaptation loop. The inner adaptation loop can be a standard RL algorithm operating on a given environment. The outer loop is tuning the hyperparameters of the inner loop such that it performs well on a wide distribution of environments. The end result of this nested training process is an algorithm that learns how to learn, i.e. learns how to adapt to tasks that have never been encountered during training. Works differ in the optimization technique and adaptation mechanism they consider in the two loops. The outer loop often optimizes higher-level structures such as the architecture of a neural network (Baker et al., 2017), the morphology (Gupta et al., 2021), a curiosity module providing intrinsic rewards (Alet et al., 2020) or plasticity rules (Najarro & Risi, 2021), employing either evolutionary or gradient-based optimization. In parallel, Reservoir Computing (RC, (Jaeger 2001+)) is particularly well suited for extracting information from data stream with complex temporal dynamics (e.g. weather forecast or language). It is a machine learning paradigm on sequential data where a recurrent neural network is only partially trained (e.g. only training a linear readout). One of the major interests of these recurrent neural networks is their reduced computational cost and the possibility to learn both in on-line and off-line fashion. They have been successfully applied on a wide variety of tasks, from prediction/generation of chaotic timeseries to discrimination of audio sequences, such as bird song recognition. They offer de facto a fast, simple yet efficient way to train RNNs. This "reservoir of computations" works thanks to random projections in large dimensions, and is thus similar to temporal Support Vector Machines (SVM). In this internship, we will explore how Reservoir Computing can be leveraged in the context of Meta-RL. In this context, we will consider evolving the architecture of a reservoir for performing well on a wide range of RL tasks (see Seoane, 2019 for theoretical arguments on this evolutionary perspective). For this aim, we will use the ReservoirPy Python library developed in the Mnemosyne team (Trouvain & Hinaut, 2022) that we will interface with evolutionary computation algorithms (e.g. Tang et al., 2022). The project will involve: ● Designing of a wide range of RL tasks in an existing simulation environment (ex MuJoCo) ● Learning how to learn multiple tasks without access to the goal information (i.e. meta-RL with a reservoir). ● Evolve reservoir architectures for meta-RL with evolutionary methods # How to apply Contact xavier.hinaut(a)inria.fr with a CV and letter of motivation. We also recommend sending documents or reports describing previous projects you have been working on (even if they are not directly related to the topic), as well as your grades and links to some of your code repositories. # Requirements We are looking for highly motivated MSc students (Master II). Programming skills and prior experience with Python and deep learning frameworks (Pytorch, Tensorflow) are expected. # Other internship offers https://github.com/neuronalX/internships/ # References Alet, F., Schneider, M.

Two postdoc openings on computational analysis and modelling of dynamic functional connectivity in Alzheimer's Disease (Strasbourg, FunSy team, France)
by Demian Battaglia Nov. 27, 2023

Nov. 27, 2023

We are happy to announce two postdoc openings in the group of Dr. Demian Battaglia, within the newly created Functional System Dynamics team at University of Strasbourg. The recruited postdocs will work as well in close collaboration with Dr. Romain Goutagny in Strasbourg and Dr. Viktor Jirsa at the Institute for Systems Neuroscience in Marseille. Both positions will focus on investigating the link between dynamics of large-scale functional connectivity and cognition: first, by assessing that the maintenance of a structured and fluid dynamics of Functional Connectivity is a predictor of cognitive performance and of its resilience despite progressing neurodegeneration; second by showing that interventions aiming at restoring "healthy" brain dynamics can rescue cognitive performance. POSITION START: as early as possible (ideally, before April 2024) POSTDOC DURATION: 24 months - TWO POSITIONS AVAILABLE Specifically the first position will delve with the study of dynamic Functional Connectivity variations and their correlation with variations of cognitive performance in longitudinal studies of aging and Alzheimer's disease cohorts (human resting state fMRI, physiological markers, cognitive profiling...). The second position will delve with the characterization of the effects of non-invasive visual gamma flickering stimulation (vGENUS) on electrophysiological activity in AD mutant mice and the modelling of the mechanisms behind these effects via virtual mouse mean-field whole-brain simulations. We are seeking for candidates, with previous experience in computational neuroscience or computer science, physics or mathematics training with strong motivation to transit toward neuroscience. Previous experience with whole-brain modelling or dynamic functional connectivity analyses would be a plus, although not strictly required. Interested candidates could have hybrid data analysis/computational modelling projects. We expect fluent programming skills (e.g., Python, C/C++, Matlab), good communication skills in English (oral and written), the ability to work well in an international team, curiosity and open-mindedness (more than applying existing methods, we tend to forge original ones, shaped by the specific scientific questions we work on). The candidate will integrate the Functional System Dynamics team (FunSy, https://funsyteam.org) at University of Strasbourg, which is a mixed theoretical and experimental group focusing on the functional roles of multi-scale system's level dynamics. FunSy research aims at linking dynamics to information processing, behavior and cognition in the healthy and pathological brain, exploring projects in rodent, non-human primate or human neuroscience as well as pure theory. The present postdoc openings are funded by the Foundation "Vaincre Alzheimer" and the French National Priority Research Investment Program "PEPR Digital Health". Strict interactions are to be expected with other partners in this initiative ("Brain Health Trajectories"), with frequent visits at Viktor Jirsa's lab at Aix-Marseille University, or other researchers at Neurospin in Saclay (Paris South) or Grenoble. Strasbourg University is home of an emergent and active community in neuroscience, from molecules and cells to whole brain imaging and behavior, in relation with clinics. The proximity with Germany and Switzerland is an asset allowing interactions with transnational computational neuroscience centers. Strasbourg, one of European Union's capitals, is a fascinating city with a rich student and cultural life, well connected via high-speed train to important European cities (e.g. less than two hours from Paris) DEADLINE FOR APPLICATION: December 24th 2023 Please send your application, including CV, motivation letter and representative publications (preprints accepted) electronically to Dr. Demian Battaglia. In addition, contacts of at least two academic references must be communicated (contact email or recommendation letter attachments). Pre-selected candidates will be interviewed over Zoom or invited to give a talk if possible. We wish to promote the recruitment of strong candidates from minority groups in STEM research. Feel free to inquire for additional requests of information. CONTACT: Demian Battaglia (dbattaglia(a)unistra.fr or demian.battaglia(a)univ-amu.fr)
