AnyEdit++: Adaptive Long-Form Knowledge Editing via Bayesian Surprise

ICML 2026poster

Editing complex, long-form knowledge in Large Language Models remains a significant challenge due to the difficulty of maintaining generation coherence. Existing autoregressive methods like AnyEdit alleviate length constraints but rely on Fixed-window Chunking, which disregards logical structure and…

Editing as Unlearning: Are Knowledge Editing Methods Strong Baselines for Large Language Model Unlearning?

AAAI 2026technical

Large language Model (LLM) unlearning, i.e., selectively removing information from LLMs, is vital for responsible model deployment. Differently, LLM knowledge editing aims to modify LLM knowledge instead of removing it. Though editing and unlearning seem to be two distinct tasks, we find there is a

Hierarchical Control for Real-Time 3D Manipulation of Magnetic Bead Using a Single Permanent Magnet

RA-L 2026

Permanent magnet (PM) actuated micro robotics offers significant advantages for minimally invasive medicine, but faces three critical challenges: nonlinear magnetic force relationships, directional control asymmetry between horizontal and vertical motion, and imaging–capturing frequency mismatch. Th

IntentRL: Training Proactive User-intent Agents for Open-ended Deep Research via Reinforcement Learning

ICML 2026poster

Deep Research (DR) agents extend Large Language Models (LLMs) beyond parametric knowledge by autonomously retrieving and synthesizing evidence from large web corpora into long-form reports, enabling a long-horizon agentic paradigm. However, unlike real-time conversational assistants, DR is computati…

MobiEdit: Resource-efficient Knowledge Editing for Personalized On-device LLMs

ICLR 2026poster

Large language models (LLMs) are deployed on mobile devices to power killer applications such as intelligent assistants. LLMs pre-trained on general corpora often hallucinate when handling personalized or unseen queries, leading to incorrect or outdated responses. Knowledge editing addresses this b…

FlowerTune: A Cross-Domain Benchmark for Federated Fine-Tuning of Large Language Models

NeurIPS 2025poster

Large Language Models (LLMs) have achieved state-of-the-art results across diverse domains, yet their development remains reliant on vast amounts of publicly available data, raising concerns about data scarcity and the lack of access to domain-specific, sensitive information. Federated Learning (FL)…

Merging LoRAs like Playing LEGO: Pushing the Modularity of LoRA to Extremes Through Rank-Wise Clustering

ICLR 2025poster

Low-Rank Adaptation (LoRA) has emerged as a popular technique for fine-tuning large language models (LLMs) to various domains due to its modular design and widespread availability on platforms like Huggingface. This modularity has sparked interest in combining multiple LoRAs to significantly enhance…

You Are Your Own Best Teacher: Achieving Centralized-level Performance in Federated Learning under Heterogeneous and Long-tailed Data

ICCV 2025poster

Data heterogeneity, stemming from local non-IID data and global long-tailed distributions, is a major challenge in federated learning (FL), leading to significant performance gaps compared to centralized learning. Previous research found that poor representations and biased classifiers are the main…

Model Tailor: Mitigating Catastrophic Forgetting in Multi-modal Large Language Models

ICML 2024poster

Catastrophic forgetting emerges as a critical challenge when fine-tuning multi-modal large language models (MLLMs), where improving performance on unseen tasks often leads to a significant performance drop on the original tasks. This paper presents a comprehensive analysis of catastrophic forgetting…

Scalable Geometric Fracture Assembly via Co-creation Space among Assemblers

AAAI 2024technical

Geometric fracture assembly presents a challenging practical task in archaeology and 3D computer vision. Previous methods have focused solely on assembling fragments based on semantic information, which has limited the quantity of objects that can be effectively assembled. Therefore, there is a need…

WISE: Rethinking the Knowledge Memory for Lifelong Model Editing of Large Language Models

NeurIPS 2024poster

Large language models (LLMs) need knowledge updates to meet the ever-growing world facts and correct the hallucinated responses, facilitating the methods of lifelong model editing. Where the updated knowledge resides in memories is a fundamental question for model editing. In this paper, we find tha…

No Fear of Classifier Biases: Neural Collapse Inspired Federated Learning with Synthetic and Fixed Classifier

ICCV 2023poster

Data heterogeneity is an inherent challenge that hinders the performance of federated learning (FL). Recent studies have identified the biased classifiers of local models as the key bottleneck. Previous attempts have used classifier calibration after FL training, but this approach falls short in imp…

Revisiting Weighted Aggregation in Federated Learning with Neural Networks

ICML 2023poster

In federated learning (FL), weighted aggregation of local models is conducted to generate a global model, and the aggregation weights are normalized (the sum of weights is 1) and proportional to the local data sizes. In this paper, we revisit the weighted aggregation process and gain new insights in…

Universal Domain Adaptation via Compressive Attention Matching

ICCV 2023poster

Universal domain adaptation (UniDA) aims to transfer knowledge from the source domain to the target domain without any prior knowledge about the label set. The challenge lies in how to determine whether the target samples belong to common categories. The mainstream methods make judgments based on th…
