In this paper, we study the effects of under-sampling (Zhang & Mani, 2003) on the neural network technique and propose some new under-sampling methods based on clustering, such that the influence of imbalanced
It also enhances the Cost-effectiveness, non-response adjustment, accuracy, and variance reduction.) and the systematic adaptive cluster sampling (SACS) technique is utilized to describe the suggested estimator. Calculations are made for the bias, mean square error (MSE), and optimization constants....
Situations when field researchers are tempted to deviate from preselected sampling plan and to include nearby or related units in sample, then adaptive cluster sampling (ACS) offers a nearly completion solution. For rare and clustered populations, Thomps

Appendix A: Sampling variability To assess the variability of clustering performance across different samples, we generated 50 datasets for each synthetic setting considered in Sect. 3.1, and computed clusterings via DBSCAN applied directly and to 2D UMAP-5 embeddings. Figure 8 shows box plots of ...

At present, using clustering technique as the main method of IDS sampling is one of the main means of downsampling strategy [15]. The vast majority of the idea is to delete the sample containing little information content after the sample clustering so as to achieve the purpose of reducing ...

In summary, CA is a type of unsupervised learning technique that eliminates the need for experts to spend time on manual labeling, making it a convenient method. Nevertheless, it is crucial to acknowledge that CA is greatly influenced by hyperparameters, includ- ing the number of clusters and ...
calculations. The ANI driven torsion sampling technique is detailed in Section S1.3. Of these torsion conformations, we randomly select 10% for CCSD(T)*/CBS calculations. The result is an enhanced ANI-1x DFT data set containing 5.2M data points and a high-accuracy CCSD(T)*/CBS data set...
