Books for the Mathematical Theory of AI/ML

I am interested in the mathematical foundations of Artificial Intelligence and Machine Learning. Are there any books which will describe and present the mathematical foundations in detail? I am not that interested in coding and would prefer a text which is heavy in mathematics and the theory.

My favorite is Understanding Machine Learning: From Theory to Algorithms. It’s presentation is very probability oriented and introduces concepts in a very concise, yet insightful way. It covers the foundations of a lot of Statistical Learning Theory and thanks to the rigorous introduction, I found it is easy to build on certain directions that interest me.
