🌲 Tree crown shyness – a photogenic phenomenon in which the crowns of fully grown trees do not touch each other. A metaphor for so many things, it really puts you to think what it means to interact.

Machine Learning (ML) is one of the most exciting and dynamic areas of modern research and application. The purpose of this review is to provide an introduction to the core concepts and tools of machine learning in a manner easily understood and intuitive to physicists. The review begins by covering fundamental concepts in ML and modern statistics such as the bias-variance tradeoff, overfitting, regularization, and generalization before moving on to more advanced topics in both supervised and unsupervised learning. Topics covered in the review include ensemble models, deep learning and neural networks, clustering and data visualization, energy-based models (including MaxEnt models and Restricted Boltzmann Machines), and variational methods. Throughout, we emphasize the many natural connections between ML and statistical physics. A notable aspect of the review is the use of Python notebooks to introduce modern ML/statistical packages to readers using physics-inspired datasets (the Ising Model and Monte-Carlo simulations of supersymmetric decays of proton-proton collisions). We conclude with an extended outlook discussing possible uses of machine learning for furthering our understanding of the physical world as well as open problems in ML where physicists maybe able to contribute.

💭 So many great mathematicians, from Archimedes, Bernoulli, Lagrange, to Pontryagin and Lions have put their stamp on "optimization" and "optimal control" problems. Here is a great summary.

When mathematicians write a review on statistical physics theories it gets pretty exciting:
