This paves the way for more data-dependent generalization guarantees in dependent-data settings.

Technique highlights:
πŸ”Ή Uses blocking methods
πŸ”Ή Captures fast-decaying correlations
πŸ”Ή Results in tight O(1/n) bounds when decorrelation is fast

Applications:
πŸ“Š Covariance operator estimation
πŸ”„ Learning transfer operators for stochastic processes

Our contribution:
We propose empirical Bernstein-type concentration bounds for Hilbert space-valued random variables arising from mixing processes.
🧠 Works for both stationary and non-stationary sequences.

Challenge:
Standard i.i.d. assumptions fail in many learning tasks, especially those involving trajectory data (e.g., molecular dynamics, climate models).
πŸ‘‰ Temporal dependence and slow mixing make it hard to get sharp generalization bounds.

We present a new empirical Bernstein inequality for Hilbert space-valued random processesβ€”relevant for dependent, even non-stationary data.

Hi Gaspard. I wonder what you are currently working on in regard to sequence models and world models. Since I have similar interests as you, and in the lab, we had worked on the intersection of the topics (bsky.app/profile/marc...).
