Neural networks are everywhere nowadays. But while it seems everyone is using them, training your first neural network can be quite a hurdle to overcome.

In this talk I will take you by the hand, and following an example image classifier I trained, I will take you through the steps of making an image classifier in PyTorch. I will show you code snippets and explain the more intricate parts. Also, I will tell you about my experience, and about what mistakes to prevent. After this all you need to start training your first classifier is a data set!

Of course I will provide a link to the full codebase at the end. The talk will focus on the practical aspect of training a neural network, and will only touch the theoretical side very briefly. Some basic prior knowledge of neural networks is beneficial, but not required, to follow this talk.

Before joining GoDataDriven, Rogier obtained a PhD in particle physics. Rogier gained hands-on experience with handling enormous quantities of data and processing, or 'charming', them into a manageable format before performing complicated analyses. After his PhD he exchanged physical science for data science at GoDataDriven, where he is now putting his skills to use on more business-driven problems. He likes applying data science to anything; be it his daily commute, improving his photography skills or the contents of his lunch box.
