MobileRL: Online Agentic Reinforcement Learning for Mobile GUI Agents

ICLR 2026poster

Building general-purpose graphical user interface (GUI) agents has become increasingly promising with the progress in vision language models. However, developing effective mobile GUI agents with reinforcement learning (RL) remains challenging due to the heavy-tailed distribution of task difficulty a…

A Non-Interventionist Approach to Causal Reasoning Based on Lewisian Counterfactuals

IJCAI 2025

We present a computationally grounded semantics for counterfactual conditionals in which i) the state in a model is decomposed into two elements: a propositional valuation and a causal base in propositional form that represents the causal information available at the state; and ii) the comparative s

ChatGLM-Math: Improving Math Problem-Solving in Large Language Models with a Self-Critique Pipeline

EMNLP 2024finding

Large language models (LLMs) have shown excellent mastering of human language but still struggle in real-world applications that require mathematical problem-solving. While many strategies and datasets to enhance LLMs’ mathematics are developed, it remains a challenge to simultaneously maintain and…

CogVideo: Large-scale Pretraining for Text-to-Video Generation via Transformers

ICLR 2023poster

In this work, we present CogVideo, a 9B-parameter transformer for text-to-video generation. The CogVideo model has been trained by inheriting a pretrained text-to-image model, CogView2, which significantly reduces the training cost and alleviates the problem of scarcity and weak relevance. We also p…
