Recursive Causal Discovery

1 code implementation14 Mar 2024 Ehsan Mokhtarian, Sepehr Elahi, Sina Akbari, Negar Kiyavash

Presence and identification of removable variables allow recursive approaches for causal discovery, a promising solution that helps to address the aforementioned challenges by reducing the problem size successively.

Contextual Combinatorial Multi-output GP Bandits with Group Constraints

no code implementations29 Nov 2021 Sepehr Elahi, Baran Atalar, Sevda Öğüt, Cem Tekin

In federated multi-armed bandit problems, maximizing global reward while satisfying minimum privacy requirements to protect clients is the main goal.

Contextual Combinatorial Bandits with Changing Action Sets via Gaussian Processes

no code implementations5 Oct 2021 Andi Nika, Sepehr Elahi, Cem Tekin

We consider a contextual bandit problem with a combinatorial action set and time-varying base arm availability.

Contextual Combinatorial Volatile Multi-armed Bandit with Adaptive Discretization

1 code implementation28 Aug 2020 Andi Nika, Sepehr Elahi, Cem Tekin

We consider contextual combinatorial volatile multi-armed bandit (CCV-MAB), in which at each round, the learner observes a set of available base arms and their contexts, and then, selects a super arm that contains $K$ base arms in order to maximize its cumulative reward.

Pareto Active Learning with Gaussian Processes and Adaptive Discretization

1 code implementation24 Jun 2020 Andi Nika, Kerem Bozgan, Sepehr Elahi, Çağın Ararat, Cem Tekin

We consider the problem of optimizing a vector-valued objective function $\boldsymbol{f}$ sampled from a Gaussian Process (GP) whose index set is a well-behaved, compact metric space $({\cal X}, d)$ of designs.
