DAG-MoE: From Simple Mixture to Structural Aggregation in Mixture-of-Experts

ICML 2026poster

Mixture-of-Experts (MoE) models have become a leading approach for decoupling parameter count from computational cost in large language models. Despite significant progress, effectively scaling MoE performance remains a challenge. Previous work shows that the use of fine-grained experts enlarges the…

Principled Synthetic Data Enables the First Scaling Laws for LLMs in Recommendation

ICML 2026poster

Large Language Models (LLMs) represent a promising frontier for recommender systems, yet their development has been impeded by the absence of predictable scaling laws, which are crucial for guiding research and optimizing resource allocation. We hypothesize that this may be attributed to the inheren…

Think Then Embed: Generative Context Improves Multimodal Embedding

ICLR 2026poster

There is a growing interest in Universal Multimodal Embeddings (UME), where models are required to generate task-specific representations. While recent studies show that Multimodal Large Language Models (MLLMs) perform well on such tasks, they treat MLLMs solely as encoders, overlooking their genera…

Quantifying Generalization Complexity for Large Language Models

ICLR 2025poster

While large language models (LLMs) have shown exceptional capabilities in understanding complex queries and performing sophisticated tasks, their generalization abilities are often deeply entangled with memorization, necessitating more precise evaluation. To address this challenge, we introduce Scy…

S'MoRE: Structural Mixture of Residual Experts for Parameter-Efficient LLM Fine-tuning

NeurIPS 2025poster

Fine-tuning pre-trained large language models (LLMs) presents a dual challenge of balancing parameter efficiency and model capacity. Existing methods like low-rank adaptations (LoRA) are efficient but lack flexibility, while Mixture-of-Experts (MoE) enhance model capacity at the cost of more & under…
