 In the present tutorial page, we will explore how the results of the [Train Model](train-ml-model.md) derived from [Machine Learning (ML)](../../models-directory/machine-learning/overview.md) can be used to predict new material [properties](../../properties/overview.md) by [linear regression](../../methods-directory/linear-regression/overview.md), such as implemented by the [Exabyte Machine Learning Engine](../../software-directory/machine-learning/exabyte/overview.md).

 # Machine Learning: Train Linear Regression
 
 This tutorial demonstrates how to build a [machine learning (ML)](../../models-directory/machine-learning/overview.md) **training model** based upon a set of [materials](../../materials/overview.md) called **"train materials"**. This model can then be used to predict the [properties](../../properties/overview.md) of another set called **"target materials"**, based on the procedure outlined in a [separate tutorial](predict-ml-properties.md).
