In the next days (18-24 July) I will be attending #ICML2022 in Baltimore. We will present in a long oral the paper “The Importance of Non-Markovianity in Maximum State Entropy Exploration”, on which I have worked during the last year of my Bachelor. 1/N.

Over the last years we understood how to control generative models via RL/control to maximize expected rewards under KL regularization. But for many applications, that’s not enough. Hence the question: can we control them further?. Excited to present our ✨Oral✨ paper “Flow

Generative models are great at mimicking data — but real (scientific) discovery requires going beyond it. Excited to present our paper “Provable Maximum Entropy Manifold Exploration via Diffusion Models” this Wednesday at ICML 2025!. We propose a scalable, theoretically grounded

How can we use RL to estimate an unknown state function by exploiting known environment invariances?. In our #ICML2024 paper (session: Wed 24th, 1.30pm), we present an algorithm that performs active exploration more efficiently by leveraging an abstract representation of the MDP.

How can we efficiently (approximately) solve an RL problem with non-additive trajectory rewards?. In our #ICML2024 paper (session: Tue 23rd, 1.30pm), we propose a meta-algorithm that solves this problem by reducing it to a specific sequence of standard MDPs.

I’ll spend the next 4 days at ICLR. Feel free to reach out if you’d like to chat! . These days I’m obsessed with the interface between decision-making (RL/bandits) and diffusion models and its application in scientific discovery🧪.
