Commonsense Subgraph for Inductive Relation Reasoning with Meta-learning (2025.coling-main)
Copied to clipboard
| Challenge: | Existing subgraph-based models focus on predicting missing relations in knowledge graphs . a new meta-learning model extracts concepts from entities to construct commonsense subgraphs based on semantic information . |
| Approach: | They propose a commonsense subgraph meta-learning model that extracts concepts from entities to construct commonsensible subgraphs. |
| Outcome: | The proposed model outperforms existing models in inductive reasoning tasks and in few-shot scenarios. |
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. |
