<p>After week 7, you will be able to communicate confidently which model features are the most important.</p>
<p>Interpretability is a very important topic in machine learning. The automated machine learning tool, <code>H2O</code>, makes a data scientist’s life easier, however it doesn’t remove the need to understand your model. As the data scientist, you need to be able to explain why the selected model is the best.</p>
<p>In this week’s curriculum, you learn how to explain “black-box” machine learning models with <code>LIME</code>. <code>LIME</code> stands for Local Interpretable Model-Agnostic Explanations and is used to understand <strong>which model features have the most predictive impact</strong>.</p>
<p></p>
<p>Here is a recap of our trajectory and the course overview:</p>

<h2>Week 7: Machine Learning Interpretability with LIME</h2>
<h3>Overview &amp; Setup</h3>
<p>The Overview &amp; Setup will walk through the setup to support <code>LIME</code> within the project workflow, and prepare the machine learning model for interpretation.</p>
<p>After understanding the features that make up your machine learning model, <strong>you will be able to answer the critical business question</strong>, <i>Why is employee churn happening?</i></p>
<p>

</p>
<p></p>
<h3>Feature Explanation With LIME</h3>
<p>Jump right into learning about the <code>LIME</code> package and how it works to interpret machine learning models. Here you will make predictions using your model and investigate employee turnover model results. You will then use LIME to produce an explanation of why certain employees were selected.</p>

</p>
<p></p>
<h3>Challenge #4</h3>
<p>In this 2 part challenge, you will recreate a single explanation plot and a full explanations plot to visualize important features.</p>
<p>After you complete the challenge, walk through the Solution videos to compare and review your working solution.</p>

<h2>Next Up</h2>
<p>The next article in the <strong><em>Data Science With R Series</em></strong> covers <strong>Evaluation: Calculating The Expected ROI (Savings) Of A Policy Change</strong>.</p>
<p>Learn how to communicate the cost savings of using your model. Inform the business to make decisions around time and resources based on <strong>the value of your findings</strong>.</p>
<p>Use the Expected Value Framework after your model is complete to explain which features are most important. The Expected Value Framework is a method to calculate savings from implementing business changes based on the model’s results.</p>
