Work done during an internship at @amazon. Huge thanks to my mentor, @zlwang_cs, and advisor, @Meng_CS, for their support in making this work possible, and to collaborators @ShiyangLi5, Xin Liu, Changlong Yu, @YinQingyu, Zhan Shi, and @zhangzxUIUC for their valuable feedback!

8/8 [Convergence rate]
The gradient-based method consistently has a higher convergence rate, reducing the required steps by 6.1 on average across RL algorithms.

7/8 [Generalizability]
We further extend experiments to different math datasets and model families. Our two methods yield superior Pareto fronts compared to the baseline, with the gradient-based weighting showing the best overall performance.

6/8 [Gradient-based weight optimization]
Our method generates superior Pareto fronts that dominate all baseline approaches under both GRPO and REINFORCE training.

5/8 [Hypervolume-guided weight adaptation]
Across all three online RL algorithms, there is consistently at least one weight configuration our method outperforms the baselines on all objectives.

Dynamic reward weights show objectives learn differently. For example, accuracy is a more challenging objective that requires continual learning, while conciseness quickly converges to 0.2.

4/8

3/8 [Preliminary finding]
Different objectives vary in learning difficulty. Each objective reaches saturation at different training stages.

Question: How to redirect learning effort towards objectives with the greatest potential for improvement.

Answer:
- If the user preference for objectives is given, use our hypervolume-based method
- If the user preference is unknown, use our gradient-based method.

ACL2025: Optimizing Decomposition for Optimal Claim Verification

This is our teaser video 😀
youtu.be/TgloG4Oefeg

Can't make it to #ACL2025 this year, but for people interested in RL for factuality and textual decomposition, please check out our paper!

TL;DR: We found a mismatch between the decomposition policy and LLM verifier, and propose a dynamic training paradigm to bridge the gap.

Optimizing Decomposition for Optimal Claim Verification Current research on the \textit{Decompose-Then-Verify} paradigm for evaluating the factuality of long-form text typically treats decomposition and verification in isolation, overlooking their interact...

Pleased to share that two papers were accepted to #ACL2025 main! Huge congratulations to all collaborators for the hard work and time we put in together!

1. Dynamic Decomposition: arxiv.org/abs/2503.15354
2. RATIONALYST: arxiv.org/abs/2410.01044

Both works study the mulit-model collobration!

Quick reminder that our paper, Benchmarking Language Model Creativity: A Case Study on Code Generation, will be presented today!

Highlighting our #NAACL2025 papers 🧵🧵🧵

I will be at #NAACL2025 to present our LLM creativity benchmark. Drop by if interested (Poster Session 8, Fri, May 2)!

I'd love to chat about RL and its interpretability, data influence for post-training, CogSci for LLM. Feel free to reach out and let's have some coffee together ☕ !
