Preference Elicitation with Soft Attributes in Interactive Recommendation

no code implementations22 Oct 2023 Erdem Biyik, Fan Yao, Yinlam Chow, Alex Haig, Chih-Wei Hsu, Mohammad Ghavamzadeh, Craig Boutilier

Leveraging concept activation vectors for soft attribute semantics, we develop novel preference elicitation methods that can accommodate soft attributes and bring together both item and attribute-based preference elicitation.

How Bad is Top-$K$ Recommendation under Competing Content Creators?

no code implementations3 Feb 2023 Fan Yao, Chuanhao Li, Denis Nekipelov, Hongning Wang, Haifeng Xu

Content creators compete for exposure on recommendation platforms, and such strategic behavior leads to a dynamic shift over the content distribution.

Learning from a Learning User for Optimal Recommendations

no code implementations3 Feb 2022 Fan Yao, Chuanhao Li, Denis Nekipelov, Hongning Wang, Haifeng Xu

In real-world recommendation problems, especially those with a formidably large item space, users have to gradually learn to estimate the utility of any fresh recommendations from their experience about previously consumed items.

Uncoupled Bandit Learning towards Rationalizability: Benchmarks, Barriers, and Algorithms

no code implementations10 Nov 2021 Jibang Wu, Haifeng Xu, Fan Yao

Under the uncoupled learning setup, the last-iterate convergence guarantee towards Nash equilibrium is shown to be impossible in many games.

DeepSteal: Advanced Model Extractions Leveraging Efficient Weight Stealing in Memories

no code implementations8 Nov 2021 Adnan Siraj Rakin, Md Hafizul Islam Chowdhuryy, Fan Yao, Deliang Fan

Secondly, we propose a novel substitute model training algorithm with Mean Clustering weight penalty, which leverages the partial leaked bit information effectively and generates a substitute prototype of the target victim model.

Learning the Optimal Recommendation from Explorative Users

no code implementations6 Oct 2021 Fan Yao, Chuanhao Li, Denis Nekipelov, Hongning Wang, Haifeng Xu

We propose a new problem setting to study the sequential interactions between a recommender system and a user.

PAC-Learning for Strategic Classification

no code implementations6 Dec 2020 Ravi Sundaram, Anil Vullikanti, Haifeng Xu, Fan Yao

In this paper, we generalize both of these through a unified framework for strategic classification, and introduce the notion of strategic VC-dimension (SVC) to capture the PAC-learnability in our general strategic setup.

T-BFA: Targeted Bit-Flip Adversarial Weight Attack

2 code implementations24 Jul 2020 Adnan Siraj Rakin, Zhezhi He, Jingtao Li, Fan Yao, Chaitali Chakrabarti, Deliang Fan

Prior works of BFA focus on un-targeted attack that can hack all inputs into a random output class by flipping a very small number of weight bits stored in computer memory.

DeepHammer: Depleting the Intelligence of Deep Neural Networks through Targeted Chain of Bit Flips

no code implementations30 Mar 2020 Fan Yao, Adnan Siraj Rakin, Deliang Fan

Security of machine learning is increasingly becoming a major concern due to the ubiquitous deployment of deep learning in many security-sensitive domains.

Greedy Step Averaging: A parameter-free stochastic optimization method

1 code implementation11 Nov 2016 Xiatian Zhang, Fan Yao, Yongjun Tian

In this paper we present the greedy step averaging(GSA) method, a parameter-free stochastic optimization algorithm for a variety of machine learning problems.
