Large Models for Small Devices: Recent Advances and Empirical Analysis of Edge AI Deployment

Subhransu Das, Jiaming Cheng, Arnav Kumar +6

Running large AI models on resource-constrained edge devices requires model compression to reduce model size and computation. What compresses well, however, need not deploy well. W…

From Hidden Profiles to Governable Personalization: Recommender Systems in the Age of LLM Agents

Jiahao Liu, Mingzhe Han, Guanming Liu +6

Personalization has traditionally depended on platform-specific user models that are optimized for prediction but remain largely inaccessible to the people they describe. As LLM-ba…

Drift-Aware Continual Tokenization for Generative Recommendation

Yuebo Feng, Jiahao Liu, Mingzhe Han +5

Generative recommendation commonly adopts a two-stage pipeline in which a learnable tokenizer maps items to discrete token sequences (i.e. identifiers) and an autoregressive genera…

Dynamic Feature-Embedding Communication via Codebook Distillation for Federated Recommendation

Mingzhe Han, Jiahao Liu, Dongsheng Li +6

Federated recommendation systems commonly protect user privacy by keeping user parameters on local devices, while exchanging item parameters for collaborative model training. Howev…

ARM2: Adaptive Reasoning Model with Vision Understanding and Executable Code

Jian Xie, Zhendong Chu, Aoxiao Zhong +5

Large Reasoning Models (LRMs) often suffer from the ``over-thinking'' problem, generating unnecessarily long reasoning on simple tasks. Some strategies have been proposed to mitiga…
