Multi-task Bias-Variance Trade-off Through Functional Constraints

no code implementations27 Oct 2022 Juan Cervino, Juan Andres Bazerque, Miguel Calvo-Fullana, Alejandro Ribeiro

In this paper we draw intuition from the two extreme learning scenarios -- a single function for all tasks, and a task-specific function that ignores the other tasks dependencies -- to propose a bias-variance trade-off.

Constrained Learning with Non-Convex Losses

no code implementations8 Mar 2021 Luiz F. O. Chamon, Santiago Paternain, Miguel Calvo-Fullana, Alejandro Ribeiro

In this paper, we overcome this issue by learning in the empirical dual domain, where constrained statistical learning problems become unconstrained and deterministic.

Towards Safe Continuing Task Reinforcement Learning

no code implementations24 Feb 2021 Miguel Calvo-Fullana, Luiz F. O. Chamon, Santiago Paternain

However, to transfer from learning safety to learning safely, there are two hurdles that need to be overcome: (i) it has to be possible to learn the policy without having to re-initialize the system; and (ii) the rollouts of the system need to be in themselves safe.

State Augmented Constrained Reinforcement Learning: Overcoming the Limitations of Learning with Rewards

no code implementations23 Feb 2021 Miguel Calvo-Fullana, Santiago Paternain, Luiz F. O. Chamon, Alejandro Ribeiro

Thus, as we illustrate by an example, while previous methods can fail at finding optimal policies, running the dual dynamics while executing the augmented policy yields an algorithm that provably samples actions from the optimal policy.

Multi-task Supervised Learning via Cross-learning

no code implementations24 Oct 2020 Juan Cervino, Juan Andres Bazerque, Miguel Calvo-Fullana, Alejandro Ribeiro

In this paper we consider a problem known as multi-task learning, consisting of fitting a set of classifier or regression functions intended for solving different tasks.

The empirical duality gap of constrained statistical learning

no code implementations12 Feb 2020 Luiz. F. O. Chamon, Santiago Paternain, Miguel Calvo-Fullana, Alejandro Ribeiro

This paper is concerned with the study of constrained statistical learning problems, the unconstrained version of which are at the core of virtually all of modern information processing.

Constrained Reinforcement Learning Has Zero Duality Gap

no code implementations NeurIPS 2019 Santiago Paternain, Luiz. F. O. Chamon, Miguel Calvo-Fullana, Alejandro Ribeiro

The later is generally addressed by formulating the conflicting requirements as a constrained RL problem and solved using Primal-Dual methods.
