The utility model has the advantages of rational design, high efficiency, convenient operation and use, fast, and high reliability, and can satisfy the sampling requirement of the particle material under variable statuses in the industry.张军成展...
2、sampler 的作用也是产生同样的一个false negatives,在采样的时候极力避开采样到这些items。 从这两方面来说,recommender和sampler 二者的目标的相同的。因此可以把sampler定义为一个分类模型 D_{S} 这样就可以在给每一个user负采样的时候,根据概率来采样 D_{S}(i|u)=1 表示分类模型认为该item是false negative...

Headspace gas VC content analysis was carried out via an auto sampler connected to an ion–molecule reaction mass spectrometer (IMR-MS). Measurements covered a mass range from 16 to 135 u including CO2, H2, N2, and O2. Prediction rules for microorganism identification based on VC composition ...
The sampler is said to produce function- ally equivalent programs if P0 and P1 agree on all inputs. The sampler is said to be difference-secure if an adversary given P0, P1, aux cannot find an input x such that P0(x) = P1(x) except with small probability. The obfuscation game picks...
