What are some effective data balancing techniques in machine learning?

Some effective data balancing techniques include oversampling, undersampling, and using synthetic data generation methods like SMOTE.

Can you explain how SMOTE works?

SMOTE, or Synthetic Minority Over-sampling Technique, generates synthetic samples for the minority class by interpolating between existing samples.

What are the pros and cons of oversampling versus undersampling?

Oversampling can lead to overfitting, while undersampling may discard useful data. The choice depends on the dataset and problem.

Are there any tools or libraries that can help with data balancing?

Yes, libraries like imbalanced-learn in Python provide various techniques for data balancing, including SMOTE and random oversampling.
