Discovering Personalized Semantics for Soft Attributes in Recommender Systems using Concept Activation Vectors

2 code implementations6 Feb 2022 Christina Göpfert, Alex Haig, Yinlam Chow, Chih-Wei Hsu, Ivan Vendrov, Tyler Lu, Deepak Ramachandran, Hubert Pham, Mohammad Ghavamzadeh, Craig Boutilier

Interactive recommender systems have emerged as a promising paradigm to overcome the limitations of the primitive user feedback used by traditional recommender systems (e. g., clicks, item consumption, ratings).

Gradient-based Optimization for Bayesian Preference Elicitation

no code implementations20 Nov 2019 Ivan Vendrov, Tyler Lu, Qingqing Huang, Craig Boutilier

Effective techniques for eliciting user preferences have taken on added importance as recommender systems (RSs) become increasingly interactive and conversational.

Data center cooling using model-predictive control

1 code implementation NeurIPS 2018 Nevena Lazic, Craig Boutilier, Tyler Lu, Eehern Wong, Binz Roy, Mk Ryu, Greg Imwalle

Despite impressive recent advances in reinforcement learning (RL), its deployment in real-world physical systems is often complicated by unexpected events, limited data, and the potential for expensive failures.

Non-delusional Q-learning and value-iteration

no code implementations NeurIPS 2018 Tyler Lu, Dale Schuurmans, Craig Boutilier

We identify a fundamental source of error in Q-learning and other forms of dynamic programming with function approximation.

Safe Exploration for Identifying Linear Systems via Robust Optimization

no code implementations30 Nov 2017 Tyler Lu, Martin Zinkevich, Craig Boutilier, Binz Roy, Dale Schuurmans

Motivated by the cooling of Google's data centers, we study how one can safely identify the parameters of a system model with a desired accuracy and confidence level.
