Darwinian Memory: A Training-Free Self-Regulating Memory System for GUI Agent Evolution

ICML 2026poster

Multimodal Large Language Model (MLLM) agents facilitate Graphical User Interface (GUI) automation but struggle with long-horizon, cross-application tasks due to limited context windows. While memory systems provide a viable solution, existing paradigms struggle to adapt to dynamic GUI environments,…

On the Generalization Ability of Next-Token-Prediction Pretraining

ICML 2025poster

Large language models (LLMs) have demonstrated remarkable potential in handling natural language processing (NLP) tasks and beyond. LLMs usually can be categorized as transformer decoder-only models (DOMs), utilizing Next-Token-Prediction (NTP) as their pre-training methodology. Despite their tremen…

Towards Trustable Skin Cancer Diagnosis via Rewriting Model's Decision

CVPR 2023poster

Deep neural networks have demonstrated promising performance on image recognition tasks. However, they may heavily rely on confounding factors, using irrelevant artifacts or bias within the dataset as the cue to improve performance. When a model performs decision-making based on these spurious corre…

Learning Network Architecture for Open-Set Recognition

AAAI 2022technical

Given the incomplete knowledge of classes that exist in the world, Open-set Recognition (OSR) enables networks to identify and reject the unseen classes after training. This problem of breaking the common closed-set assumption is far from being solved. Recent studies focus on designing new losses, n…
