Feature selection with selective sampling
WebNov 18, 2024 · We could choose a sampling method based on whether we want to account for sampling bias; a random sampling method is often preferred over a non-random method for this reason. Random sampling examples include: simple, systematic, stratified, and cluster sampling. Non-random sampling methods are liable to bias, and common … WebSample selection is a key factor in research design and can determine whether research questions will be answered before the study has even begun. Good sample selection and appropriate sample size strengthen a study, protecting valuable time, money and resources. In the context of healthcare research, poor design could lead to use of harmful practices, …

WebJan 2, 2024 · The new approach uses a differentially private feature selection method that is based on a data sampling process over a kd-tree (Friedman et al. 1976 ). The approach presents a differentially private kd-tree then samples representative entries from the kd-tree; finally, data aggregates are returned from the sampled dataset.
WebA recent work [4] proposes a feature selection methodbased on selec-tive sampling. The idea is to reduce the computational cost of the feature selection by reducing the number of sampled data points. Random sam-pling is replaced by selective sampling that exploits the data distribution to detect the most informative examples.
