Machine learning is the future for the next generation of software professionals.

This course serves as a guide to machine learning for software engineers. You’ll be introduced to three of the most relevant components of the AI/ML discipline; supervised learning, neural networks, and deep learning. You’ll grasp the differences between traditional programming and machine learning by hands-on development in supervised learning before building out complex distributed applications with neural networks. You’ll go even further by layering networks to create deep learning systems. You’ll work with complex real-world datasets to explore machine behavior from scratch at each phase.

By the end of this course, you’ll have a working knowledge of modern machine learning techniques. Using software engineering, you’ll be prepared to build complex neural networks and wrangle real-world data challenges.

Fundamentals of Machine Learning for Software Engineers

There is no such thing as a perfect replacement for the sigmoid. Different activation functions work well in different circumstances, and researchers keep coming up with the new ones. That being said, one activation function has proven so broadly useful that it’s become a default of sorts. Let’s discuss it in the next section.

## Enter the ReLU
The go-to replacement for the sigmoid these days is the **rectified linear unit** or **ReLU**. Compared with the sigmoid, the ReLU is surprisingly simple. Here’s a Python implementation of it:
