๐ Keywords: Diffusion Language Models, Frequency-Domain Analysis, FourierSampler, Low-Frequency Components, High-Frequency Components
๐ก Category: Generative Models
๐ Research Objective:
– The investigation delves into the spectral characteristics of diffusion language models to address positional bias and enhance arbitrary generation capabilities.
๐ ๏ธ Research Methods:
– The research employs frequency-domain analysis to distinguish between low-frequency components, which encode global structures, and high-frequency components, which detail local features. The FourierSampler with a dynamic frequency-domain sliding window is introduced to optimize generation.
๐ฌ Research Conclusions:
– FourierSampler significantly improves inference outcomes, achieving notable performance over autoregressive models and other strategies in benchmarks such as LLADA and SDAR, with specific improvements of 20.4% and 16.0% on different datasets.

39. Do Reasoning Models Enhance Embedding Models?
๐ Keywords: RLVR, Embedding Models, HRSA, Local Geometry Reorganization, Manifold Realignment
๐ก Category: Knowledge Representation and Reasoning
๐ Research Objective:
– To determine if embedding models initialized from RLVR-tuned reasoning models have a performance advantage over base models in semantic representation.
๐ ๏ธ Research Methods:
– Evaluation on MTEB and BRIGHT datasets using Hierarchical Representation Similarity Analysis (HRSA) to analyze similarity across representation, geometry, and function levels.
๐ฌ Research Conclusions:
– Embedding models initialized from RLVR-tuned backbones show no consistent performance advantage over base models. Although RLVR reorganizes local geometry and preserves global manifold geometry, subsequent contrastive learning aligns base- and reasoning-initialized models effectively.

41. Quartet II: Accurate LLM Pre-Training in NVFP4 by Improved Unbiased Gradient Estimation
๐ Keywords: NVFP4, NVIDIA Blackwell GPUs, quantized training, gradient estimation, LLM training
๐ก Category: Machine Learning
๐ Research Objective:

๐ ๏ธ Research Methods:
– Introduction of a novel unbiased quantization routine called MS-EDEN, integrated into a fully-NVFP4 quantization scheme named Quartet II, which is applied to linear layers to enhance gradient estimation and matrix multiplication processes.
๐ฌ Research Conclusions:
– Quartet II shows improved gradient estimation and execution speed, achieving up to a 4.2x speedup over BF16 on NVIDIA Blackwell GPUs. This method also performs well in end-to-end LLM training on vast sets of parameters and tokens.
