CoMem: Compositional Concept-Graph Memory for Vision–Language Adaptation

ICLR 2026poster

Continual vision–language learning is crucial for multimodal tasks such as image–text retrieval, visual question answering, and grounded reasoning in dynamic environments, yet deployed systems must learn from non-stationary streams under strict privacy and memory budgets, where naïve finetuning forg…

From Points to Coalitions: Hierarchical Contrastive Shapley Values for Prioritizing Data Samples

AAAI 2026technical

How should we quantify the value of each training example when datasets are large, heterogeneous, and geometrically structured? Classical Data-Shapley answers in principle, but its O(n!) complexity and point-wise perspective are ill-suited to modern scales. We propose Hierarchical Contrastive Data V

Influence-Disentangled Federated Training: Learning Models That Are Easy to Unlearn

ICML 2026poster

Federated learning increasingly faces deletion requests that require client-level unlearning without sacrificing model quality, yet a client’s influence is often deeply entangled after many rounds of aggregation. We aim to make unlearning fast, stable, and predictable by reducing the gap to leave-on…

Meta-UCF: Unified Task-Conditioned LoRA Generation for Continual Learning in Large Language Models

ICLR 2026poster

Large language models are increasingly deployed in settings where newtasks arrive continuously, yet existing parameter-efficient finetuning (PEFT) methods either bloat linearly with the task horizon or sacrifice deep adaptation, leaving catastrophic forgetting unresolved. We aim to achieve memory-co…

Diffusion-Based Self-Supervised Imitation Learning from Imperfect Visual Servoing Demonstrations for Robotic Glass Installation

ICRA 2025

Heavy-duty glass installation is a high-risk, precision-critical task in modern construction, traditionally performed through labor-intensive and error-prone manual methods. This paper presents a novel robotic framework that leverages diffusion-based self-supervised imitation learning from imperfect
