In order to effectively enhance classified performance of the minority kind in the imbalanced data set, we proposed one kind minority kind of sample sampling method based on the K-means cluster and the genetic algorithm in view of this question. We used K-means algorithm to cluster and group ...

Sample selection in positivist and interpretivist studies Probability sampling or randomsample selectionis often used in positivist research. If a researcher wishes to generalise from a sample to the population from which it has been selected, the sample must be randomly selected, as described above...
sampling of primitive asteroids and the need to transport returned samples in totally inert and sterile conditions. The evidence presented here shows that Ryugu particles are undoubtedly among the most uncontaminated Solar System materials available for laboratory study and ongoing investigations of these ...
The first step in using this calculator is to describe the research you are conducting. Sampling method: This calculator can work with three sampling methods: simple random sampling, stratified sampling, and cluster sampling. With stratified sampling, you have the option to choose proportional stratif...
