PID Control-Based Self-Healing to Improve the Robustness of Large Language Models

1 code implementation31 Mar 2024 Zhuotong Chen, Zihu Wang, Yifan Yang, Qianxiao Li, Zheng Zhang

This approach reduces the computational cost to that of using just the P controller, instead of the full PID control.

Logic-Scaffolding: Personalized Aspect-Instructed Recommendation Explanation Generation using LLMs

no code implementations22 Dec 2023 Behnam Rahdari, Hao Ding, Ziwei Fan, Yifei Ma, Zhuotong Chen, Anoop Deoras, Branislav Kveton

The unique capabilities of Large Language Models (LLMs), such as the natural language text generation ability, position them as strong candidates for providing explanation for recommendations.

Asymptotically Fair Participation in Machine Learning Models: an Optimal Control Perspective

no code implementations16 Nov 2023 Zhuotong Chen, Qianxiao Li, Zheng Zhang

Moreover, we design a surrogate retention system based on existing literature on evolutionary population dynamics to approximate the dynamics of distribution shifts on active user counts, from which the objective of achieving asymptotically fair participation is formulated as an optimal control problem, and the control variables are considered as the model parameters.

Self-Healing Robust Neural Networks via Closed-Loop Control

1 code implementation26 Jun 2022 Zhuotong Chen, Qianxiao Li, Zheng Zhang

While numerous attack and defense techniques have been developed, this work investigates the robustness issue from a new angle: can we design a self-healing neural network that can automatically detect and fix the vulnerability issue by itself?

Towards Robust Neural Networks via Close-loop Control

1 code implementation ICLR 2021 Zhuotong Chen, Qianxiao Li, Zheng Zhang

We connect the robustness of neural networks with optimal control using the geometrical information of underlying data to design the control objective.
