Workshop: Machine Learning Glassy Dynamics

Amorphous materials such as glasses have been used since prehistoric times, but in recent years their technological applications have rapidly grown. However, despite many decades of research using experiments, theory and computer simulations, fundamental mechanisms such as mechanical properties and stress relaxation in glasses are still poorly understood. In recent years, machine learning techniques have started to be applied to help solve these fundamental questions, creating a new research path to study disordered materials. This workshop is dedicated to understanding the role that machine learning can play in better understanding glasses from a fundamental perspective. The original format should trigger new collaboration work between different actors and help organise this rapidly growing research field.

Message passing methods on complex networks
Review article by M. E. J. Newman

Networks and network computations have become a primary mathematical tool for analyzing the structure of many kinds of complex systems, ranging from the Internet and transportation networks to biochemical interactions and social networks. A common task in network analysis is the calculation of quantities that reside on the nodes of a network, such as centrality measures, probabilities, or model states. In this review article we discuss message passing methods, a family of techniques for performing such calculations, based on the propagation of information between the nodes of a network. We introduce the message passing approach with a series of examples, give some illustrative applications and results, and discuss the deep connections between message passing and phase transitions in networks. We also point out some limitations of the message passing approach and describe some recently-introduced methods that address these limitations.

Landau theory for the Mpemba effect through phase transitions
Roi Holtzman & Oren Raz

The Mpemba effect describes the situation in which a hot system cools faster than an identical copy that is initiated at a colder temperature. In many of the experimental observations of the effect, e.g. in water and clathrate hydrates, it is defined by the phase transition timing. However, none of the theoretical investigations so far considered the timing of the phase transition, and most of the abstract models used to explore the Mpemba effect do not have a phase transition. We use the phenomenological Landau theory for phase transitions to identify the second order phase transition time, and demonstrate with a concrete example that a Mpemba effect can exist in such models.

Predicting personality, death, emigration, and other life-events from embeddings of registry data

Over the past decade, machine learning has revolutionised computers’ ability to analyze text through flexible computational models. Beyond text, emerging transformer-based architectures have shown promise as tools to make sense of a range of multi-variate sequences from protein-structures to weather-forecasts due to their structural similarity to written language. Another type of process which has a strong structural similarity to language is human lives. From one perspective, lives are simply sequences of events: We are born, we visit the pediatrician, we start school, we move to a new location, we get married, and so on. Here, we use this similarity to adapt innovations from natural language processing to examine the evolution and predictability of human lives based on day-to-day event sequences.
