Taught me backpropagation
Format: Paperback
I'm finding this book a great reference to supplement Syracuse IST 691 Deep Learning in Practice. In particular, its explanation of backpropagation is the clearest I have found yet, and that even includes 3 Blue 1 Brown, which always does excellent explanations.

An Easy Read
Format: Paperback
A good narrative description of how the various systems work. Good for getting a conceptual understanding. No math to speak of, and if you want it, you can refer to the references cited, or your other favorite machine learning book.

No Irritation!!
Size: 1 Count (Pack of 1), Color: Black Razor
Had been looking at this as a replacement for an adjustable razor I'd been using for years and finally purchased it here on Amazon. Wow! What a difference! Very nice quality, the blades lock in securely and are perfectly aligned. Did not use the included blades as I've read they are not the best quality so used my trusted Astra platinum. Great shave and zero irritation! Great thing about this razor is if you do not hold it at the 30 degree angle it was designed for it will not shave but best of all it will not cut you! Great razor for beginners or experienced shavers. FIVE STARS!

Great razor! Recommend 10/10
Size: 1 Count (Pack of 1), Color: Rose Gold Razor
Love this razor. Previously had a Solara razor, this was way cheaper and honestly feels like better quality. However, important note… do not take it with you if you are flying with a carry on! It was an innocent mistake, I didn’t think anything of it but because it’s a single, removable blade, you cannot take it through TSA

Great little razor!
Good product! It’s pretty easy to use, it has some heft to it, the blades are sharp, can’t complain especially for the price.
