How do you deal with a class imbalance in ML?

7 Techniques to Handle Imbalanced Data

  1. Use the right evaluation metrics.
  2. Resample the training set.
  3. Use K-fold Cross-Validation in the right way.
  4. Ensemble different resampled datasets.
  5. Resample with different ratios.
  6. Cluster the abundant class.
  7. Design your own models.

Which is the best dataset for imbalanced multiclass classification?

Problems of this type are referred to as imbalanced multiclass classification problems and they require both the careful design of an evaluation metric and test harness and choice of machine learning models. The E.coli protein localization sites dataset is a standard dataset for exploring the challenge of imbalanced multiclass classification.

How to deal with an imbalanced dataset?

Synthetic Minority Over-Sampling Technique is one of the most commonly used oversampling methods to solve the imbalance problem. It aims to balance class distribution by randomly increasing minority class examples by replicating them. Again for the dataset, I am using the SMOTE algorithm to balance the dataset with the parameter k_neighbors = 5.

What is the imbalanced multiclass dataset for E.coli?

In this project, we will use a standard imbalanced machine learning dataset referred to as the “ E.coli ” dataset, also referred to as the “ protein localization sites ” dataset. The dataset describes the problem of classifying E.coli proteins using their amino acid sequences in their cell localization sites.

What is the problem of multi class imbalanced classification?

In this tutorial, we will focus on the standard imbalanced multi-class classification problem referred to as “ Glass Identification ” or simply “ glass .” The dataset describes the chemical properties of glass and involves classifying samples of glass using their chemical properties as one of six classes.
