Learning GUI Grounding with Spatial Reasoning from Visual Feedback

ICML 2026poster

Graphical User Interface (GUI) grounding is commonly framed as a coordinate prediction task – given a natural language instruction, generate on-screen coordinates for actions such as clicks and keystrokes. However, recent Vision Language Models (VLMs) often fail to predict accurate numeric coordinat…

Text2Grad: Reinforcement Learning from Natural Language Feedback

ICLR 2026poster

Traditional RLHF optimizes language models with coarse, scalar rewards that mask the fine-grained reasons behind success or failure, leading to slow, opaque learning. Recent work augments RL with textual critiques through prompting or reflection, improving interpretability but leaving model paramete…

DI-BENCH: Benchmarking Large Language Models on Dependency Inference with Testable Repositories at Scale

ACL 2025finding

Large Language Models have advanced automated software development, however, it remains a challenge to correctly infer dependencies, namely, identifying the internal components and external packages required for a repository to successfully run. Existing studies highlight that dependency-related iss…

GUI-Actor: Coordinate-Free Visual Grounding for GUI Agents

NeurIPS 2025poster

One of the principal challenges in building VLM-powered GUI agents is visual grounding—localizing the appropriate screen region for action execution based on both the visual content and the textual plans. Most existing work formulates this as a text-based coordinate generation task. However, these a…

OpenRCA: Can Large Language Models Locate the Root Cause of Software Failures?

ICLR 2025poster

Large language models (LLMs) are driving substantial advancements in software engineering, with successful applications like Copilot and Cursor transforming real-world development practices. However, current research predominantly focuses on the early stages of development, such as code generation,…

RuAG: Learned-rule-augmented Generation for Large Language Models

ICLR 2025poster

In-context learning (ICL) and Retrieval-Augmented Generation (RAG) have gained attention for their ability to enhance LLMs' reasoning by incorporating external knowledge but suffer from limited contextual window size, leading to insufficient information injection. To this end, we propose a novel fra…

Call Me When Necessary: LLMs can Efficiently and Faithfully Reason over Structured Environments

ACL 2024findings

Large Language Models (LLMs) have shown potential in reasoning over structured environments, e.g., knowledge graphs and tables. Such tasks typically require multi-hop reasoning, i.e., match natural language utterance with instances in the environment. Previous works adopt LLMs to incrementally build…

Everything of Thoughts: Defying the Law of Penrose Triangle for Thought Generation

ACL 2024findings

This paper introduce a novel thought prompting approach called ”Everything of Thoughts” (XoT) for Large Language Models (LLMs) to defy the law of ”Penrose triangle” of existing thought paradigms, to achieve three key perspectives in thought generation simultaneously: performance, efficiency, and fle…

QueryAgent: A Reliable and Efficient Reasoning Framework with Environmental Feedback based Self-Correction

ACL 2024long

Employing Large Language Models (LLMs) for semantic parsing has achieved remarkable success. However, we find existing methods fall short in terms of reliability and efficiency when hallucinations are encountered. In this paper, we address these challenges with a framework called QueryAgent, which s…

CloudLSTM: A Recurrent Neural Model for Spatiotemporal Point-cloud Stream Forecasting

AAAI 2021technical

This paper introduces CloudLSTM, a new branch of recurrent neural models tailored to forecasting over data streams generated by geospatial point-cloud sources. We design a Dynamic Point-cloud Convolution (DConv) operator as the core component of CloudLSTMs, which performs convolution directly over p…
