1/n Today, we concluded @icmlconf with 4 presentations at the #FORLAC workshop conjoining RL theory and Control. Following their UAI work, @tuanquangdam, Odalric & Emilie on their work to address biased value function estimation in #MCTS using power means. #ICML2024 @Inria_Lille

3/n MCTS with deep NN shows promising performance in deterministic envs, but fails in stochastic envs. @tuanquangdam, Odarlic & Brahim propose CATS & PATS, leveraging TS to handle selection randomness. They achieve regret guarantees as well as good performance in stochastic envs.

4/n Alena, Thomas, Phillipe & Bruno motivated by uniqueness ambiguity of value func as a solution to HJB eqn in CTRL, propose to approximate the value func by training a PINN through a specific scheduling iterative process that constraints it to converge to the viscosity solution

Congratulations to @tuanquangdam, Odalric, and Emilie on their work to address biased value function estimation in #MCTS using power means. 🥳 #UAI2024 @Inria_Lille @RechercheUlille

#UAI2024 Interested in how power mean can enhance value function estimation in tree search methods? Learn about our approach to solving biases in MCTS for stochastic settings. Join us tomorrow at 4:30 PM in the Exhibition room, building 20.

We've derived tight lower and upper bounds for differentially private finite-armed & linear bandits, while we lack the same for contextual bandits. At #COLT2024, @achraf_azize presents open problems in contextual bandits with privacy. @BasuDebabrota @Inria_Lille @RechercheUlille

It's fun to revisit the sanctum sanctorum: how does a brain learn? Today at Convention on Mathematics of #Neuroscience & #AI, @GuillaumeAP presents our work with @AdityaGilra on how to design a bio-plausible learning rule rather than backprop type methods to learn a time series.

1/2 Is exploration harder if we've constraints on policies? No, depends on how constraints change the geometry of alternating set. Today @aistats_conf, @BasuDebabrota & collaborators present insights & algorithms for pure exploration with constraints. #AISTATS2024 @chalmersuniv

2/2 If each arm has multiple objectives, how to identify an arm whose mean vector is not worse than any of the others. Tomorrow @aistats_conf, Emilie & Cyrille will present "first" algo to detect such pareto sets with finite budget & bandit feedback. @RechercheUlille @Inria_Lille

1/2 To define privacy in bandits, we have to ask what are the input and output of a bandit algorithm? What differs if the adversary is interactive or passive? @achraf_azize & @BasuDebabrota address these in their work openreview.net/forum?id=2366….

2/2 Today @satml_conf, @achraf_azize is presenting these nuances of "Concentrated DP for Bandits" along with information-theoretic lower bounds and near-optimal algorithms for linear, contextual, and multi-armed bandits. #privacy #bandits @Inria_Lille @RechercheUlille #SaTML24

What happens in a bandit problem if epsilon fraction of feedback are arbitrarily corrupt? What are the new lower bounds on the regret? Can we design an optimal algorithm for #Bandits_corrupted_by_nature? We address this question in two parts.

Today at #ALT2024, @ShubhadaAgrawal presents CRIMED: a joint work with Timothée, @BasuDebabrota & Odalric. CRIMED achieves matching regret upper bound for symmetric distributions and unbounded corruption. #bandits #corrupted_observations @univ_lille @Inria_Lille

@TmlrOrg we address the corrupted bandit problem, i.e. a stochastic multi-armed bandit problem with unknown reward distributions, which are heavy-tailed and corrupted by a history-independent adversary or Nature. We provide another set of lower bounds and algorithm. #robustness

What happens if you've multiple objectives/rewards for each arm? How can you find pareto set with bandits? At 5PM @NeurIPSConf, Cyrille'll present an adaptive & sequential sampling to identify Pareto set (or a relaxed Pareto set) of multivariate distributions #NeurIPS23 #Bandit
