Reliable Conditioning of Behavioral Cloning for Offline Reinforcement Learning

1 code implementation11 Oct 2022 Tung Nguyen, Qinqing Zheng, Aditya Grover

We study CWBC in the context of RvS (Emmons et al., 2021) and Decision Transformers (Chen et al., 2021), and show that CWBC significantly boosts their performance on various benchmarks.

A Simple and Scalable Tensor Completion Algorithm via Latent Invariant Constraint for Recommendation System

no code implementations27 Jun 2022 Tung Nguyen, Sang T. Truong, Jeffrey Uhlmann

In this paper we provide a latent-variable formulation and solution to the recommender system (RS) problem in terms of a fundamental property that any reasonable solution should be expected to satisfy.

Tensor Completion with Provable Consistency and Fairness Guarantees for Recommender Systems

no code implementations4 Apr 2022 Tung Nguyen, Jeffrey Uhlmann

The framework and solution algorithms also generalize directly to tensors of arbitrary dimensions while maintaining computational complexity that is linear in problem size for fixed dimension d. In the context of recommender system (RS) applications, we prove that two reasonable properties that should be expected to hold for any solution to the RS problem are sufficient to permit uniqueness guarantees to be established within our framework.
