Usage: technical; statistics; research

Examples

• The researchers used subsampling to reduce the dataset from 10,000 to 1,000 participants.
• Subsampling helped speed up the analysis while maintaining statistical validity.
• The survey employed random subsampling to ensure representative results.
• Due to budget constraints, subsampling was necessary for the clinical trial.
• The computer algorithm performed subsampling to process the large image files.
• Subsampling techniques are commonly used in machine learning applications.
