The course creator

Meet your teacher

Robert Plummer

Robert is a full stack engineer, and the lead developer of the Brain.js library. He has a unique ability to explain complex concepts in a manner that everyone can understand.

Why this

course rocks

This course gives you a practical introduction to Brain.js, a popular JavaScript library for building neural networks in the browser and in Node.js. And since this is Scrimba, you'll be able to interact with the neural networks whenever you want. Simply pause the screencast, edit the code and run the network with your own changes applied. Learning machine learning has never been as interactive as this!

What you'll learn

By the end of the course, you'll be able to solve a range of different problems using neural networks. The lectures does not dwell with much theory, but rather on how to code the networks. That means the course is suitable for anybody who knows JavaScript.

Good luck, and welcome to the exciting world of neural networks!

F to the A to the Q

Are neural networks machine learning?

Neural networks are a specific set of algorithms within machine learning. They are inspired by biological neural networks and the current so-called deep neural networks and have proven to work quite well.

What are neural networks and deep learning?

Neural networks are biologically-inspired programming concept which enables a computer to learn from observational data. Deep learning is a set of techniques for learning in neural networks.

What can neural networks do?

In short, neural networks can be used for solving business problems such as forecasting, customer research, data validation, and risk management. A more fun use could be to teach a neural network to play Mario cart.

What are the major benefits of neural networks?

Ability to learn and model non-linear and complex relationships, which is really important because in real-life, many of the relationships between inputs and outputs are non-linear as well as complex.
