Data splitting in machine learning
WebFeb 1, 2024 · Motivation. Dataset Splitting emerges as a necessity to eliminate bias to training data in ML algorithms. Modifying parameters of a ML algorithm to best fit the training data commonly results in an overfit algorithm that performs poorly on actual test data. For this reason, we split the dataset into multiple, discrete subsets on which we train ... WebDec 29, 2024 · The train-test split technique is a way of evaluating the performance of machine learning models. Whenever you build machine learning models, you will be training the model on a specific dataset (X …
