tokenspeed hits 580 tps on qwen3.5-397b-a17b for agentic workloads
tokenspeed inference engine achieves 580 tokens per second on qwen3.5-397b-a17b by eliminating memory copies and overlapping cpu-gpu execution.
delta weight sync cuts rl model transfer costs
trl now uploads only changed weights between rl steps, reducing per-step payload from gigabytes to megabytes using sparse safetensors and hugging face buckets.
small models pay a constraint tax for structured output
forcing small language models to produce valid json or schemas can hurt answer quality, a tradeoff measured as constraint tax.
cart forests as sequential allocation over random opportunity sets
a new stochastic-control theory explains how cart random forests work by viewing feature subsampling as random opportunity sets and split rules as allocation policies.
neural bayesian sequential routing
a framework that models neural inference as active evidence accumulation over a hierarchical dag, enabling uncertainty-aware routing and early stopping.
silhouette scoring boosts isolation forest for fraud detection
adding a silhouette-based scoring layer to isolation forest improves unsupervised fraud detection on a large benchmark dataset.
gem: geometric entropy mixing for llm data curation
a new framework uses hypersphere geometry and entropy to find balanced data mixtures for training large language models.
