Papers with reinforcement learning methods
FinBPM: A Framework for Portfolio Management-based Financial Investor Behavior Perception Model (2024.eacl-long)
Copied to clipboard
| Challenge: | a portfolio management framework based on reinforcement learning is needed to optimize stock price movements. |
| Approach: | They propose a framework that takes irrational investment into account when calculating portfolio weights . they use financial text to analyze intrinsic value information of companies and time series data . |
| Outcome: | The proposed framework gains 13.26% returns over state-of-the-art models while controlling for risk. |
Enhancing multi-modal Relation Extraction with Reinforcement Learning Guided Graph Diffusion Framework (2025.coling-main)
Copied to clipboard
| Challenge: | Existing methods for cross-modal relation extraction focus on single-modal data, which limits their use in real-world situations. |
| Approach: | They propose a framework that leverages pre-trained models to encode multi-modal data into scene graphs and combine them into a cross-modal graph. |
| Outcome: | The proposed model outperforms existing methods on multi-modal relation extraction tasks. |
No Metrics Are Perfect: Adversarial Reward Learning for Visual Storytelling (P18-1)
Copied to clipboard
| Challenge: | Visual captioning is aimed at depicting the concrete content of images, but its capability of performing human-like understanding is still restrictive. |
| Approach: | They propose an Adversarial REward Learning framework to learn an implicit reward function from human demonstrations and optimize policy search with the learned reward function. |
| Outcome: | The proposed framework improves performance over state-of-the-art (SOTA) methods in cloning expert behaviors, but human evaluation shows that it achieves significant improvement in generating more human-like stories than SOTA systems. |
Rethinking Supervised Learning and Reinforcement Learning in Task-Oriented Dialogue Systems (2020.findings-emnlp)
Copied to clipboard
| Challenge: | Dialogue policy learning for task-oriented dialogue systems has enjoyed great progress through using reinforcement learning methods. |
| Approach: | They propose a dialogue action decoder and a simulator-free adversarial learning method to improve dialogue agent performance without using reinforcement learning. |
| Outcome: | The proposed methods achieve more stable and higher performance with fewer efforts, such as the domain knowledge required to design a user simulator and the intractable parameter tuning in reinforcement learning. |
MatchTIR: Fine-Grained Supervision for Tool-Integrated Reasoning via Bipartite Matching (2026.acl-long)
Copied to clipboard
| Challenge: | Existing reinforcement learning methods rely on outcome- or trajectory-level rewards, assigning uniform advantages to all steps within a trajectory. |
| Approach: | They propose a framework that introduces fine-grained supervision via bipartite matching-based turn-level reward assignment and dual-level advantage estimation. |
| Outcome: | The proposed framework surpasses the majority of 8B competitors on three benchmarks. |
A Collaborative Multi-agent Reinforcement Learning Framework for Dialog Action Decomposition (2021.emnlp-main)
Copied to clipboard
| Challenge: | Currently, most reinforcement learning methods for dialog policy learning train a centralized agent that selects a predefined joint action concatenating domain name, intent type, and slot name. |
| Approach: | They propose a hierarchical multi-agent framework in which each part of the action is led by a different agent and a joint optimization process that makes agents can exchange their policy information. |
| Outcome: | The proposed framework reduces labor costs for action templates and decreases the size of the action space for each agent. |
