If you want a book on the details of AI without math and statistics, this is it
Format: Paperback
I had this book a year or two back and then sold a lot of books as they piled up. After that I read a good number of books on AI. Of those, Ethan Mollick's book Co-Intelligence is best for the user end. But then there was still the issue of how do they do it?
If you want to understand the process how AI works, there are a few books like this. Melanie Mitchell tends to focus on pictures. When you read ANY of these book, you will come to a page where you think "this makes no sense." You get there because the way AI chops up information and stores it in "cells" and then processes in stages (deep learining, hidden layers) is not how we think. They are not brains, though the neural network has some similarity to ours. You will simply need to finish the book. This one or the one you bought. Then read another one, if needed. It will make a lot of sense if you finish the book. Then you just generalize where you are at. I am never going to write Python or get deeply involved in tha manner. I am quite familiar with the free vesrions and I am able to check what summaries I get from AI. I will also keep up with the language part of it. AI does not study grammar the way we do. It looks for patterns in millions of examples.
I have since 2023 gone through most of the 20 dollar range books. This one is the best.

Great, funny intro to AI
Format: Hardcover
This is a wonderful, humorous introduction to AI that is a fast read packed full of examples. It makes a great gift for friends or family who don’t know much about the field, and I imagine it would be especially interesting to teens. I loved the way she used running jokes to make connections between themes. Shane is clearly on a mission to make AI more accessible.
It’s funny, someone else said they didn’t like this book because it wasn’t enough like Shane’s tear-inducingly-hilarious blog. But here’s the thing: I can read the blog for free! I was actually nervous that I was going to be getting a repeat of the blog in book form, but it was super different. If you’re a computer science scholar, maybe skip this one, but I don’t think that was the audience Shane was trying to reach.

Humorous intro-level book to AI
Format: Hardcover
If you are new to the field of AI, this is a fun read. The author does a fine job breaking down complex topics into bite-size, entertaining sections. However, if you are not new to the field of AI, you'll probably find this book boring and will find more joy in visiting the author's popular website.
Personally, I find this book forgettable and not living up to the hype.

Captivating storytelling and educational material
Format: Paperback
My ten years old boy loved WW2 in Europe: Great Battles for Boys. He likes to read about war and it his third book from Joe Giorello. It is an engaging and easy-to-understand account of significant World War II moments designed for young boys. It has pictures and maps so they can have a better understanding about the War and through captivating storytelling and educational material, it provides a valuable introduction to this crucial era, promoting a greater comprehension and respect for the experiences and achievements of individuals during that time.

Why are these books so hard to find in libraries and bookstores??!
Format: Paperback
Bought nearly the whole book series after reading the reviews. My 8 and 10 year old boys love these books. My 10 year old read the first book on his way to and from soccer practice. He couldn't put it down and kept telling me what he read. My boys have read all the "Magic Treehouse", "I Survived" and some "I Escaped" books, as well as "Big Nate", "Diary of a Wimpy Kid", etc. BUT these battle books are the best. They really teach about the history of the wars which have shaped our modern times. WHY are these books so hard to find in libraries and bookstores... at least in Maryland? Maybe because "Great Battles for Boys" reeks of toxic masculinity? I really wonder. In any case, great books especially if you want your boys to read serious, informative books that are interesting and entertaining.
