Data Leakage in Machine Learning

Data leakage is a big problem in machine learning when developing predictive models. Data leakage is when information from outside the training dataset is used to create the model. In this post you will discover the problem of data leakage in predictive modeling. After reading this post you will know: What is data leakage is in predictive modeling. Signs of data leakage and why it is a problem. Tips and tricks that you can use to minimize data leakage on your predictive modeling problems. Let’s get started.
