Lagrange: An Open-Vocabulary, Energy-Based Sparse Framework for Generalized End-to-End Driving

Shihao Ji, HongXi Li, Zihui Song +1

Scaling end-to-end autonomous driving to complex, open-world environments requires perceptual models that generalize to anomalous scenarios and planners that produce kinematically…

A Formal Kinetic Theory for Zeroth-Order Newton Dynamics:Stein-Corrected Hessian Estimation and Curvature--Variance Trade-offs

Shihao Ji, Mingyu Li, Zihui Song

Zeroth-order Newton-type methods are useful when gradients and Hessians are unavailable, but they behave quite differently from first-order gradient-free methods. We develop a kine…

Expected Value Alignment for Generative Reward Modeling in Formal Mathematics Verification

Shihao Ji, Haotao Tan, Zihui Song +1

Large Language Models (LLMs) are increasingly used with formal interactive theorem provers such as Lean 4. Scaling these systems with reinforcement learning or search methods requi…

Soft-NBCE: Entropy-Weighted Chunk Fusion for Long-Context

Shihao Ji, Mingyu Li, Zihui Song

The quadratic complexity of self-attention remains a bottleneck for Large Language Models (LLMs) processing ultra-long contexts. The Naive Bayes Cognitive Engine (NBCE) parallelize…

E-comIQ-ZH: A Human-Aligned Dataset and Benchmark for Fine-Grained Evaluation of E-commerce Posters with Chain-of-Thought

Meiqi Sun, Mingyu Li, Junxiong Zhu

Generative AI is widely used to create commercial posters. However, rapid advances in generation have outpaced automated quality assessment. Existing models emphasize generic esthe…

A Survey of Context Engineering for Large Language Models

Lingrui Mei, Jiayu Yao, Yuyao Ge +12

The performance of Large Language Models (LLMs) is fundamentally determined by the contextual information provided during inference. This survey introduces Context Engineering, a f…
