WebOversampling (Upsampling) the minority class. Oversampling randomly duplicates observations from the minority class in order to make its signal stronger. The simplest form of oversampling is sampling with replacement. Oversampling is suitable when you don’t have a lots of observations in your dataset (<10K observations). WebThe imbalanced data classification problem widely exists in many real-world applications. Data resampling is a promising technique to deal with imbalanced data through either …
