Foundations of Geometric Deep Learning I
The success of deep learning applied to images, speech, and text has spurred research into the application of similar techniques to other kinds of data, such as graphs, points clouds, data on homogeneous spaces, and other manifolds. This field has come to be known as geometric deep learning. In this talk I will discuss the foundations of GDL, focusing on the basic concepts of symmetry groups, representations, and equivariant maps, as well as group & gauge equivariant convolutions for fields over homogeneous spaces and general manifolds.

Representations, networks, and symmetries for learning from particle physics data
In experimental high energy physics (HEP), we collide high energy particle beams millions of times per second and observe the remnants of the collisions with hundreds of millions of detector channels. There is a growing interest in exploiting machine learning methods to extract physics from this raw detector data. In order to benefit from modern deep learning algorithms initially designed for computer vision or natural language processing tasks, it is common practice to transform HEP data into tabular data, images, or sequences. In this lecture, I will review these machine learning methods, as well as emerging methods like graph neural networks and symmetryequivariant networks, which provide alternative ways of incorporating specialized domain knowledge.
As part of the CMS experiment at the CERN Large Hadron Collider, Javier Duarte’s group performs measurements of highmomentum Higgs bosons and searches for exotic new physics. They are also interested in hardwareaccelerated machine learning for trigger and computing as well as geometric deep learning for particle physics.

Dylan Rankin, Postdoc, MIT/IAIFI
Tutorial I for Model compression and fast machine learning in particle physics: Training Invariant Networks
In this tutorial, we will explore neural network architectures that are capable of respecting the different inherent symmetries in datasets. We will use simulated data from particle physics and consider both symmetries of permutation invariance and Lorentz equivariance. We will construct successively more complex models that are capable of respecting these symmetries, and analyze how the architecture choices we make affect the model performance and learning. Finally, we will offer an opportunity to explore more complex symmetries and give participants an opportunity to test what they have learned on these more difficult problems.
Dylan Rankin received his Ph.D. in 2018 from BU under Tulika Bose, and is currently a postdoc at MIT with Phil Harris. He will start as a faculty member at UPenn this coming spring. He is interested in machine learning, heterogeneous computing, trigger and data acquisition systems, Higgs physics, and exotic searches. His work is focused on using novel analysis methods both at the CERN Large Hadron Collider and beyond.

Model compression and fast machine learning in particle physics
Efficient machine learning implementations optimized for inference in hardware have wideranging benefits, from lower inference latency to higher data throughput and reduced energy consumption. In this lecture, I will give an overview of effective techniques for reducing computation in neural networks, including pruning, or removing insignificant synapses, quantization, or reducing the precision of the calculations, and knowledge distillation, or transferring the knowledge from a large model to a smaller model. I will also review the connections to the lottery ticket hypothesis, interpretability, neural efficiency, robustness, and generalizability.

Tutorial for Model compression and fast machine learning in particle physics: Compressing Neural Networks for Ultrafast Inference
In this tutorial, we will explore how to apply different techniques to reduce the size and necessary computation for neural network inference while maintaining model performance. We will begin with models trained using standard techniques using floating point numbers. We will show how to apply pruning techniques to reduce the size of the networks by removing unnecessary connections. We will also show how to quantize the networks to reduce the number of bits necessary for encoding values during inference. In both cases, we will show how these techniques can be applied while maintaining desired model performance to allow for inference on lowpower devices such as FPGAs. Finally, participants will analyze the ramifications of these techniques on the latency and resources of synthesized designs for FPGAbased inference.

Deep learning in the largewidth regime I
We will review some of the foundational connections that arise between deep neural networks and other classic machine learning methods, albeit modified with new ingredients, in the limit where the neural network hidden layers have many nodes. These connections have been used across different research areas, including in the development of deep learning theory; in building new connections between machine learning and statistical physics; as well as in machine learning practice, including applications to physics. In the tutorials, we will gain experience with neural network libraries built to enable the recursive computations that form the core of these connections.

Sven Krippendorf, Senior Researcher, Mathematical Physics and String Theory, LudwigMaximilians Universität
Machine Learning for BeyondtheStandardModel Physics I
These lectures aim to give an overview on how we can tackle questions in BeyondTheStandardModel (BSM) physics using Machine Learning (ML). I will discuss a few types of questions to showcase how ML approaches can be adapted to fit into standard physics pipelines:

How can we understand the pattern of experimentally viable BSM theories? Such models feature on the one hand consistency conditions from their respective UVcompletion selecting a subset of theories at lowenergies. On the other hand, the requirement of matching observations at lowenergies poses apriori unknown constraints on the UV parameters, a classic inverse problem. I discuss how ML can help in addressing this inverse problem. A short preview can be obtained at 2111.11466.

How can we phrase the search for mathematical structures as optimisation problems? This is to discuss how we can identify the symmetries associated to a dynamical system using ML and how we can accelerate the search for solutions of PDEs using ML. References of interest for this part are: 1906.01563, 2104.14444, 2003.13679, 2012.04656

How can we use ML to accelerate the physics inference pipeline? Depending on time, this part will feature heavily in the tutorials.

Machine learning for manybody physics I
Over the past few years, machine learning (ML) has emerged as a powerful computational tool to tackle complex problems in various scientific disciplines. In particular, ML has been successfully used to mitigate the exponential complexity often encountered in manybody physics, the study of properties of quantum and classical systems built from a large number of interacting particles. In these lectures, we review some applications of ML in statistical mechanics, condensed matter physics, and quantum information. We will discuss select examples drawing from ML areas including supervised machine learning of phase transitions, unsupervised learning of quantum states, and the variational Monte Carlo method for approximating the ground state of a manybody Hamiltonian. For each algorithm, we briefly review the key ingredients and their corresponding implementation and show numerical experiments for a system of interacting Rydberg atoms in two dimensions among other systems.

Siddharth MishraSharma, IAIFI Fellow
Tutorial for Machine Learning for BeyondtheStandardModel Physics: Modeling and inference: connecting theory and data
Principled comparison of theory with observations is a bedrock of the scientific method, underlying in particular how information about fundamental physics can be extracted from data. Using contemporary physics examples, these handson tutorials will introduce strategies for defining statistical models, implementing them as (differentiable) probabilistic programs, and performing inference on them. Various inference methods will be discussed, including samplingbased (e.g., Markov Chain Monte Carlo), variational inference and, time permitting, simulationbased (“likelihoodfree”) inference.
Siddharth is an IAIFI Fellow at MIT interested in developing novel statistical methods for accelerating the discovery of new physics in astrophysical and cosmological observations at all accessible scales. He is especially focused on developing analysis techniques based on machine learning that enable new ways of searching for signatures of physics beyond the Standard Model, in particular the nature of dark matter, using data from ongoing and upcoming cosmological surveys.
