Data Leakage in Machine Learning

Aug 15, 2020Data 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.

Leakage (machine learning) Wikipedia

In statistics and machine learning, leakage (also data leakage, or target leakage) is the use of information in the model training process which would not be expected to be available at prediction time, causing the predictive scores (metrics) to overestimate the model's utility when run in a production environment.. Leakage is often subtle and indirect, making it hard to detect

Data Leakage in Machine Learning. How to prevent issues

Jul 16, 2019Data leakage refers to a mistake make by the creator of a machine learning model in which they accidentally share information between the test and training data-sets. Typically, when splitting a data-set into testing and training sets, the goal is to ensure that no data is shared between the two.

Demining Wikipedia

Demining or mine clearance is the process of removing land mines from an area. In military operations, the object is to rapidly clear a path through a minefield, and this is often done with devices such as mine plows and blast waves. By contrast, the goal of humanitarian demining is to remove all of the landmines to a given depth and make the land safe for human use.
