ReLATE: Accelerating Tensor Decomposition via Safe and Efficient Learning of Sparse Encodings

Read the original on arXiv Machine Learning →

ReLATE is a reinforcement‑learned framework that automatically discovers safe and efficient sparse encodings for tensor decomposition, eliminating the need for expert‑designed formats. It combines model‑free and model‑based learning, elastic training, rule‑driven action masking, and dynamics‑informed filtering to guarantee correct encoding with bounded execution time, even early in training. After offline training, ReLATE deploys the optimal encoding with negligible overhead and achieves up to 2× speedups over the best expert‑designed format, with a geometric‑mean speedup of 1.38–1.41× on diverse real‑world sparse tensors.

ExFold: Unified Expert Folding for Training-Free MoE Prefill-Decode Acceleration

ExFold is a training‑free expert‑folding framework that jointly accelerates the prefill and decode phases of Mixture‑of‑Experts (MoE) models by projecting the contributions of excluded experts onto a retained expert set using calibrated scalar projectors. It treats both phases as a budgeted output‑approximation problem, achieving token‑level Top‑K folding for prefill and batch‑level expert‑pool folding for decode. Implemented as a plug‑and‑play plugin in vLLM with a lightweight CUDA kernel, ExFold delivers up to 1.41× TTFT and 2.45× TPOT speedups while preserving about 99% of the original model quality.

Finetuning Vision-Language-Action Models Requires Fewer Layers Than You Think

arXiv:2606. 20246v1 Announce Type: cross Abstract: Vision-Language-Action (VLA) models pre-trained on massive video-robot datasets have revolutionized robotic manipulation, yet their multi-billion parameter architectures impose prohibitive computational burdens during downstream fine-tuning and real-time inference.
