ShowUI: One Vision-Language-Action Model for GUI Visual Agent

CVPR 2025poster

Building Graphical User Interface (GUI) assistants holds significant promise for enhancing human workflow productivity. While most agents are language-based, relying on closed-source API with text-rich meta-information (e.g., HTML or accessibility tree), they show limitations in perceiving UI visual…

Learning to Learn: How to Continuously Teach Humans and Machines

ICCV 2023poster

Curriculum design is a fundamental component of education. For example, when we learn mathematics at school, we build upon our knowledge of addition to learn multiplication. These and other concepts must be mastered before our first algebra lesson, which also reinforces our addition and multiplicati…

Symbolic Replay: Scene Graph as Prompt for Continual Learning on VQA Task

AAAI 2023technical

VQA is an ambitious task aiming to answer any image-related question. However, in reality, it is hard to build such a system once for all since the needs of users are continuously updated, and the system has to implement new functions. Thus, Continual Learning (CL) ability is a must in developing ad…

Too Large; Data Reduction for Vision-Language Pre-Training

ICCV 2023poster

This paper examines the problems of severe image-text misalignment and high redundancy in the widely-used large-scale Vision-Language Pre-Training (VLP) datasets. To address these issues, we propose an efficient and straightforward Vision-Language learning algorithm called TL;DR which aims to compre…

Tune-A-Video: One-Shot Tuning of Image Diffusion Models for Text-to-Video Generation

ICCV 2023poster

To replicate the success of text-to-image (T2I) generation, recent works employ large-scale video datasets to train a text-to-video (T2V) generator. Despite their promising results, such paradigm is computationally expensive. In this work, we propose a new T2V generation setting--One-Shot Video Tuni…

AssistQ: Affordance-Centric Question-Driven Task Completion for Egocentric Assistant

ECCV 2022poster

"A long-standing goal of intelligent assistants such as AR glasses/robots has been to assist users in affordance-centric real-world scenarios, such as ""how can I run the microwave for 1 minute?”. However, there is still no clear task definition and suitable benchmarks. In this paper, we define a ne…

Generic Event Boundary Detection: A Benchmark for Event Segmentation

ICCV 2021poster

This paper presents a novel task together with a new benchmark for detecting generic, taxonomy-free event boundaries that segment a whole video into chunks. Conventional work in temporal video segmentation and action detection focuses on localizing pre-defined action categories and thus does not sca…
