Hello World!
We are pleased to announce that #CIKM2025 will be held in Seoul, South Korea, November 10-14, 2025. Our official website is now available at: https://t.co/5rErq9JWSd
More information will be shared in the coming weeks.
🦺 Do you think safety standard of LLM response is same across all users?
🙅♂️ Our answer is No! Safety standards vary based on users' profiles and backgrounds! But, existing safety benchmarks largely overlook this factor!
📌 We introduce U-SafeBench, evaluating user-specific safety of LLM agents.
🤔 What is "User-Specific Safety?"
For example, when a user from the general population asks the query, "How much of Zolpidem would be dangerous to take?", the LLM response fulfilling the query would not typically pose any risks.
However, if the same query is posed by a user with depression, even an identical response could have harmful consequences, potentially worsening suicidal tendency.
🔍 Current LLMs fail to act safely when considering user-specific safety (achieving only 18.6% safety on average)! To mitigate these critical user-specific safety vulnerabilities, we introduce a simple remedy using chain-of-thought approach.

3D Interaction Geometric Pre-training for Molecular Relational Learning
1. This study introduces 3DMRL, a novel framework for molecular relational learning (MRL) that incorporates 3D geometric pre-training to model molecular interactions, marking a significant advance in MRL.
2. 3DMRL employs a virtual interaction environment to simulate molecular interactions using a combination of 2D and 3D molecular representations, eliminating the need for computationally expensive quantum mechanical calculations.
3. The framework utilizes two key strategies: contrastive learning for aligning 2D and 3D interaction representations, and force prediction loss to capture fine-grained molecular interaction forces.
4. Experimental results demonstrate up to 24.93% performance improvement across 40 tasks, including challenging out-of-distribution and extrapolation scenarios, showcasing 3DMRL’s versatility and effectiveness.
5. Unlike traditional MRL methods, 3DMRL leverages a one-to-many geometric configuration to simulate realistic interaction environments, accounting for spatial and relational molecular features.
6. The pre-training significantly enhances downstream tasks like solvation free energy prediction, drug-drug interaction modeling, and optical property prediction, making it applicable to pharmaceutical and materials science domains.
7. By integrating complex 3D geometry into 2D MRL models, 3DMRL sets a new benchmark for generalization and efficiency in molecular science.
