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

# Chapter Goals:

<ul>
  <li>Add the final layers to the MLP for multiclass classification</li>
</ul>

<h2>A. Final layer activation</h2>
<p>In the <b>Intro to Deep Learning</b> section, we built the MLP classification models such that each model produced <a href="https://en.wikipedia.org/wiki/Logit" target="_blank">logits</a>. This is because the TensorFlow <a href="https://en.wikipedia.org/wiki/Cross_entropy" target="_blank">cross-entropy</a> loss functions applied the sigmoid/softmax function to the output of the MLP.</p>
<p>In Keras, the cross-entropy loss functions only calculate cross-entropy, without applying the sigmoid/softmax function to the MLP output. Therefore, we can have the model directly output class probabilities instead of logits (i.e. we apply sigmoid/softmax activation to the output layer).</p>
