这就是top-k sampling:在解码的每个时间步从前k个概率最大的词中按它们的概率进行采样。 但top-k sampling中k的选择是个难题,选大了可能会采样出长尾词,导致语句不通顺,选小了又退化成了Beam Search。 Nucleus Sampling (Top-p Sampling) 为解决这个问题,Nucleus sampling应运而生: The key intuition of ...

We used single nucleus suspensions from all tested protocols as input for droplet-based snRNA-Seq (see Methods), thus sampling sufficiently large numbers of cells to evaluate cell diversity and QCs. Fig. 4: Frozen tumor processing and protocol selection for snRNA-Seq. a, Flow chart for ...
However, we confirmed that the post-mortem sampling intervals between the controls and AD subjects do not differ significantly (Fig. S9), suggesting that our results were not confounded by transcriptional changes induced by death. Importantly, future studies employing multiscale dynamical models of ...

It is not recommended to modify Temperature and NucleusSamplingFactor for the same chat completions request as the interaction of these two settings is difficult to predict. NucleusSamplingFactor is equivalent to 'top_p' in the REST request schema. Applies to ПродуктВерсии Azure ...
11,22,44 EEG/EMG signals were amplified and filtered (EEG, 0.5–30 Hz; EMG, 20–200 Hz), and were then digitized at a sampling rate of 128 Hz. EEG power spectra were calculated for consecutive 4 s epochs within the frequency range of 0–25 Hz using fast-Fourier transformation. EEG ...
The sampling procedure was in accordance with the ethical guidelines of the Medical University-Sofia (Bulgaria), the Saint Louis University (USA), and the University of Antwerp (Belgium). Peripheral blood mononuclear cells (PBMC) were isolated on a Ficoll-Paque gradient, transformed with Epstein-...
including the REN+cells that are known to associate with the juxtaglomerular apparatus, were only rarely detected within the vSMC/P cluster based onRENtranscript levels (Supplementary Fig.11a). This indicates that deeper sampling would be needed for greater diversification of interstitial subpopulations...
