Beyond Sequences: Distilling Structured Decision Memory for LLM Recommendation

Despite the adoption of large language models (LLMs) in recommendation systems, prevailing approaches mostly model single-type behaviors (e.g., views or purchases). Even when incorporating multiple behaviors, existing methods flatten heterogeneous actions into homogeneous token sequences, ignoring their distinct decisi...

Muon Sublates the Edge of Stability in LLM Pretraining

Results support a split EoS picture for Muon: a stochastic loss-neutral edge survives, but it is not accompanied by a universal temporal-direction signature, and directions remain far from coherent reversal while training continues to improve.

SPAE: Spectrally Guided Autoencoder for Pretrained Visual Latents

SPAE employs a compact bottleneck to distill stable semantic information while suppressing high-frequency components, thereby improving the alignment between DiT-generated latents and encoder latents, and achieves a favorable balance among visual understanding, generation quality, and reconstruction fidelity.
