Imbalanced-Learn module in Python - GeeksforGeeks

Witryna11 gru 2024 · Practice. Video. Imbalanced-Learn is a Python module that helps in balancing the datasets which are highly skewed or biased towards some classes. Thus, it helps in resampling the classes which are otherwise oversampled or undesampled. If there is a greater imbalance ratio, the output is biased to the class which has a higher … Witryna13 lut 2024 · IMBENS is developed on top of imbalanced-learn (imblearn) and follows the API design of scikit-learn. Compared to imblearn, IMBENS provides more powerful ensemble learning algorithms with multi-class learning support and many other advanced features: 🍎 Unified, easy-to-use APIs, detailed documentation and examples.
