Multi-Head Latent Control: A Unified Interface for LLM Agent Decision Making

Amirhosein Ghasemabadi, Ruichen Chen, Bahador Rashidi +1

The paper proposes Multi-Head Latent Control, a lightweight add‑on that reads hidden‑state trajectories from a frozen LLM or VLM to decide whether to continue reasoning, defer to a…

2D Pre-Training for 3D Pose Estimation

Liyao Jiang, Ruichen Chen, Keith G. Mills

Pre-training is a general method that is used in a range of deep learning tasks. By first training a model on one task, and then further training on the downstream task used for fi…

RAISE: Requirement-Adaptive Evolutionary Refinement for Training-Free Text-to-Image Alignment

Liyao Jiang, Ruichen Chen, Chao Gao +1

Recent text-to-image (T2I) diffusion models achieve remarkable realism, yet faithful prompt-image alignment remains challenging, particularly for complex prompts with multiple obje…

FP4DiT: Towards Effective Floating Point Quantization for Diffusion Transformers

Ruichen Chen, Keith G. Mills, Di Niu

Diffusion Models (DM) have revolutionized the text-to-image visual generation process. However, the large computational cost and model footprint of DMs hinders practical deployment…

Re-ttention: Ultra Sparse Visual Generation via Attention Statistical Reshape

Ruichen Chen, Keith G. Mills, Liyao Jiang +2

Diffusion Transformers (DiT) have become the de-facto model for generating high-quality visual content like videos and images. A huge bottleneck is the attention mechanism where co…

QuaSeDiMo: Quantifiable Quantization Sensitivity of Diffusion Models

Keith G. Mills, Mohammad Salameh, Ruichen Chen +3

Diffusion Models (DM) have democratized AI image generation through an iterative denoising process. Quantization is a major technique to alleviate the inference cost and reduce the…
