Visual learners will love this
Format: Paperback
This book is amazing for the visual learner! I've taken numerous online classes that use animated videos to explain deep learning concepts visually, but this book accomplishes the same thing in print! I've also purchased deep learning books with pages and pages of formulas and hardly any illustrations. My brain can't process symbolic math without a picture. Kudos on creating something truly unique and super valuable.

statquest, you know it is good
Format: Paperback
I have been watching Josh's statquest youtube channel for 10 years. Josh is very good at explaining complex machine-learning concepts in an easy-to-understand way. I bought my team the last statquest guide to machine learning book and they loved it. So when this is out, I bought six copies for my team too. It is a great investment for yourself. so go and grab a copy! Thanks, Josh for making such a resource!
