MicLog: Towards Accurate and Efficient LLM-based Log Parsing via Progressive Meta In-Context Learning

AAAI 2026technical

Log parsing converts semi-structured logs into structured templates, forming a critical foundation for downstream analysis. Traditional syntax and semantic-based parsers often struggle with semantic variations in evolving logs and data scarcity stemming from their limited domain coverage. Recent lar

M3DSS: A Multi-Platform, Multi-Sensor, and Multi-Scenario Dataset for SLAM System

ICRA 2025

This paper proposed M3DSS, a multi-platform, multi-sensor, and multi-scenario dataset for Simultaneous Localization and Mapping (SLAM) systems. Fifty-five sequences were collected from multiple platforms, including a handheld equipment, an unmanned ground vehicle, a quadruped robot, a car, and an un

Online Preference Alignment for Language Models via Count-based Exploration

ICLR 2025spotlight

Reinforcement Learning from Human Feedback (RLHF) has shown great potential in fine-tuning Large Language Models (LLMs) to align with human preferences. Existing methods perform preference alignment from a fixed dataset, which can be limited in data coverage and the resulting reward model is hard to…

Constrained Ensemble Exploration for Unsupervised Skill Discovery

ICML 2024poster

Unsupervised Reinforcement Learning (RL) provides a promising paradigm for learning useful behaviors via reward-free per-training. Existing methods for unsupervised RL mainly conduct empowerment-driven skill discovery or entropy-based exploration. However, empowerment often leads to static skills, a…

Contrastive Representation for Data Filtering in Cross-Domain Offline Reinforcement Learning

ICML 2024poster

Cross-domain offline reinforcement learning leverages source domain data with diverse transition dynamics to alleviate the data requirement for the target domain. However, simply merging the data of two domains leads to performance degradation due to the dynamics mismatch. Existing methods address t…

ODRL: A Benchmark for Off-Dynamics Reinforcement Learning

NeurIPS 2024poster

We consider off-dynamics reinforcement learning (RL) where one needs to transfer policies across different domains with dynamics mismatch. Despite the focus on developing dynamics-aware algorithms, this field is hindered due to the lack of a standard benchmark. To bridge this gap, we introduce ODRL,…

OEE-CFC: A Dataset for Open Event Extraction from Chinese Financial Commentary

EMNLP 2024finding

To meet application needs, event extraction has shifted from simple entities to unconventional entities serving as event arguments. However, current corpora with unconventional entities as event arguments are limited in event types and lack rich multi-events and shared arguments. Financial commentar…

Cross-Domain Policy Adaptation via Value-Guided Data Filtering

NeurIPS 2023poster

Generalizing policies across different domains with dynamics mismatch poses a significant challenge in reinforcement learning. For example, a robot learns the policy in a simulator, but when it is deployed in the real world, the dynamics of the environment may be different. Given the source and targ…

Diffusion Model is an Effective Planner and Data Synthesizer for Multi-Task Reinforcement Learning

NeurIPS 2023poster

Diffusion models have demonstrated highly-expressive generative capabilities in vision and NLP. Recent studies in reinforcement learning (RL) have shown that diffusion models are also powerful in modeling complex policies or trajectories in offline datasets. However, these works have been limited to…

Open-Ended Diverse Solution Discovery with Regulated Behavior Patterns for Cross-Domain Adaptation

AAAI 2023technical

While Reinforcement Learning can achieve impressive results for complex tasks, the learned policies are generally prone to fail in downstream tasks with even minor model mismatch or unexpected perturbations. Recent works have demonstrated that a policy population with diverse behavior characteristic…

High-Flexibility Locomotion and Whole-Torso Control for a Wheel-Legged Robot on Challenging Terrain

ICRA 2020poster

In this paper, we propose a parallel six-wheel-legged robot that can traverse irregular terrain while carrying objectives to do heavy-duty work. This robot is equipped with six Stewart platforms as legs and tightly integrates the additional degrees of freedom introduced by the wheels. The presented…
