WebIn the second course of the Machine Learning Specialization, you will: • Build and train a neural network with TensorFlow to perform multi-class classification • Apply best practices for machine learning development so that your models generalize to data and tasks in the real world • Build and use decision trees and tree ensemble methods, including random … WebMar 28, 2016 · 4. Cost Sensitive Learning (CSL) It is another commonly used method to handle classification problems with imbalanced data. It’s an interesting method. In simple words, this method evaluates the cost associated with misclassifying observations. It does not create balanced data distribution.

WebAug 6, 2024 · The evaluation metrics used in each of these models are different. In classification problems, we use two types of algorithms (dependent on the kind of output it creates): Class output: Algorithms like SVM and KNN create a class output. For instance, in a binary classification problem, the outputs will be either 0 or 1.
