Meanwhile, hospitals may be biased toward shorter lifespans, because they tend to admit the toughest cases, not healthy dogs.'It's not good data, but it gets you in the ballpark,'says Prof. 另一方面,医院提供的狗寿命可能会比较短,因为医院遇到的多是健康状况糟糕的狗。
Partitioning by a has of user id would presumably have been nearly balanced-so it's likely that a biased partitioning ( e.g., putting older users on one shard) resulted in the imbalanced data growth. 通过用户ID划分的分区大体上来说是均衡的&可能是有倾向性的分区(例如把旧用户放到一个Shard上)会导致不均衡的数据增长。
Calibration and Evaluation of Uncertainty in Measurement of Electric Parameter Instrument exonerate by means of a perfunctory investigation or through biased presentation of data. 电参数测量仪的校准和不确定度评定通过马马虎虎的调查或通过不准确的数据显示就断定某人无罪。
These differences between the two groups of patients could have biased and significantly influenced the safety data from these studies. 患者的组间差异可能导致偏差并显著影响这项研究的安全性数据。
He could have explained that the hedge fund industry's performance claims are based on biased return data. 他也可以解释说,对冲基金行业的表现,声称是基于偏颇的回报数据。
Applications of Biased Estimator in GPS Data Processing 有偏估计在GPS快速定位数据处理中的应用研究
Density Biased Sampling And Its Applications Research in Large Data Sets 密度偏差抽样及其在海量数据挖掘中的应用
The major results in the paper are abstracted as follows: 1 we synthesized the DNA sequence of A and B strand of human insulin with soybean biased codon after analyzing the soybean codon bias according to the cDNA data of soybean in GeneBank. 根据大豆偏爱密码子和GeneBank中的人胰岛素A、B链氨基酸序列,人工合成了人胰岛素A、B链基因。
Biased Sampling of Data Streams Based on Density 密度相关的数据流偏倚抽样
We have analyzed the main thought, characteristic and improvement method of density biased sampling, have carried on the contrast analysis, and its application in cluster in the mass data mining to carry on the thorough discussion. 研究分析了密度偏差抽样的主要思想,特点及其改进方法,进行了对比分析,并对密度偏差抽样在海量数据挖掘中主要是聚类领域的应用进行了深入探讨。
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。
On the other hand, this paper establishes a Shell Neighbor Classification method ( SNC). It is not biased in selecting nearest neighbors. The SNC algorithm is not sensitive to distance metrics and performs better at classification accuracy on large data sets. 另一方面,本论文建立一个壳近邻分类算法SNC,克服了kNN最近邻选择上可能存在偏好这一问题,该算法对距离度量不敏感,在大数据集上具有更好的分类效果。
Robust estimate and biased estimate of regression coefficients are two kinds of regression model fitting methods for non-optimal data. 回归系数的稳健估计和有偏估计是两种根据非典型数据建立线性回归模型的方法。
The difficulties and innovation of this paper is in selecting factors to represent the Guizhou rural financial support and rural economic growth. And the research result could be biased from the accuracy due to the data selection. 难点在于,在进行实证分析时,对代表农村金融支持和代表农村经济增长的要素的选取,因为数据选取的较单一性,可能会在某种程度上偏离研究结果的准确性。
