Correlation in machine learning code
WebMar 19, 2024 · 4. When we want to encode the categorical features to numerical features for applying the machine learning algorithms since ML algorithms only understand numbers not text. So for this task, we use the concept of the Dummy variable. Inaccurate use of Dummy variables can also cause multicollinearity. (This is known as Dummy Variable Trap) WebApr 13, 2024 · Semi-supervised learning is a learning pattern that can utilize labeled data and unlabeled data to train deep neural networks. In semi-supervised learning methods, self-training-based methods do not depend on a data augmentation strategy and have better generalization ability. However, their performance is limited by the accuracy of predicted …
