If you're a software engineer looking to add machine learning to your skillset, this is the place to start. 

This course will teach you to write useful code and create impactful machine learning applications immediately. From the start, you'll be given all the tools that you need to create industry-level machine learning projects. Rather than reading through dense theory, you’ll learn practical skills and gain actionable insights. Topics covered include data analysis/visualization, feature engineering, supervised learning, unsupervised learning, and deep learning. All of these topics are taught using industry-standard frameworks: NumPy, pandas, scikit-learn, XGBoost, TensorFlow, and Keras.

Basic knowledge of Python is a prerequisite to this course.

This course was created by AdaptiLab, a company specializing in evaluating, sourcing, and upskilling enterprise machine learning talent. It is built in collaboration with industry machine learning experts from Google, Microsoft, Amazon, and Apple.

Machine Learning with NumPy, pandas, scikit-learn, and More

<h2 style="font-size:1.1em">Chapter Goals:</h2>
<ul>
  <li>Evaluate model performance on a test set</li>
</ul>

<h2>A. Evaluating using accuracy</h2>
<p>After training a model, it is a good idea to evaluate its performance. We do this by using a <i>test set</i> (i.e. data points not used in model training) and observe the model's prediction accuracy on the test set.</p>
<p>The code for this chapter makes use of the <code>accuracy</code> metric defined in Chapter 4. The accuracy represents the classification accuracy of an already trained model, i.e. the proportion of correct predictions the model makes on a test set.</p>

<h2>Chapter Goals:</h2>
<ul>
  <li>Evaluate model performance on a test set</li>
</ul>

Evaluate a fully trained neural network using the model accuracy as the evaluation metric.
