AppCoda Weekly - Issue #186

By AppCoda Weekly • Issue #187 • View online

We’ve been working with Vardhan Agrawal, an iOS developer who has been actively contributed to the machine learning community, to write a book on machine learning and Core ML. Now we are happy to announce that the book “Mastering Machine Learning with Core ML and Python” is now available for early access.

This book covers Core ML in-depth. You will learn how to create and deploy your own machine learning model. On top of that, you will learn about Turi Create, Create ML, Keras, Firebase, and Jupyter Notebooks, just to name a few.

Since we are still updating the book for Xcode 12 and iOS 14, we are offering a great discount before the official release. If you want to learn machine learning and Core ML, check out the book here.

As always, we got a great collection of tutorials for your reading this weekend. Hope you enjoy it!

Regards,

Simon
