Biased Sampling of Data Streams Based on Density

密度相关的数据流偏倚抽样

We use the density biased sampling as a data reduction technique to speed up the clustering data mining tasks in large multidimensional data sets.

可以按照数据集的密度应用偏差抽样来加速常规数据挖掘任务的运行，本文对此进行了研究。

The new STM 32 XL density devices are now sampling to lead customers.

新的STM32XL高密度产品目前正向大客户提供测试样品.

In the high mountain area under arid climate, stream sediment geochemical survey at the 1/ 50000 scale was carried out with the sampling density of 4 points per square kilometer. The grain size of the sample in initial preparation stage was-20~+ 120 mesh.

在干旱高山景观区，以4点/km2的采样密度，选择-20~+120目粒级段为初加工粒级，开展1∶5万水系沉积物地球化学测量。

Sp 1, were presented in the seawater samples, accounting for 11.6% of total dinoflagellate species number and 0-51.3% of dinoflagellate cell density found in the water column during the sampling period.

sp1，几乎全是该潮间带底栖甲藻的优势种，占水样中甲藻种数的11.6%。个体数占海水样品中甲藻总个体密度的0～51.3%，具有明显的季节性。

To improve efficiency and veracity of soil sampling in testing bulk density, the cutting ring method and in situ soil tube method were combined and a multi-segment in situ soil sampler was designed.

为了提高土壤容重测定中土样采集的效率和精准性，将环刀法和原状取土管法结合，进行了分段式原状取土器的研制。
