Here, I will describe optimal betting strategies that give the highest capital growth rate while keeping a certain low value of risk, that is, an optimal trade-off between the average and the fluctuations. This trade-off is also embodied in a general bound similar to thermodynamic uncertainty relations. Finally, I will discuss possible future applications in biology. This trade-off is also believed to operate in situations known generically in biology as "bet-hedging". Organisms may exchange a reduction of their present fitness for increased fitness in a possible future stressful condition. Some type of bet-hedging mechanism is believed to operate in the production of seeds by plants or in the resistance to antibiotics. Zoom Meeting ICTP pio@ictp.it 20 Apr 2021

Europe/Rome 2021-06-15 08:00:00 2021-06-18 22:00:00 Youth in High-Dimensions | (smr 3602) An ICTP virtual meeting The aim of the conference is to give young researchers the opportunity to present their results related to high-dimensional statistical problems, as arising in machine learning, inference or statistical physics.   Typical problems in high-dimensions include the detection and estimation of noisy signals (compressed sensing, PCA and tensor decomposition etc), the analysis of (deep) neural-networks and their learning and generalization dynamics, the detection of communities in large networks, or disordered spin systems. While these problems may seem of different natures, they actually share many similarities in their common phenomenology and the tools used to analyze them. The core of the field is made of a very active, diverse and quickly expanding community of physicists, computer scientists, mathematicians, information theorists and engineers, with the common desire to tackle increasingly challenging problems at the forefront of data science. This conference aims at reinforcing the links among this interdisciplinary community, and in particular of its youngest theory-oriented members, and to bring forward the latest development happening in the high-dimensional world.

Europe/Rome 2021-07-05 08:00:00 2021-07-30 22:00:00 London Mathematical Laboratory Summer School | (smr 3598) An ICTP virtual meeting The London Mathematical Laboratory (LML) is pleased to announce its 2021 Summer School. This will be held as an ICTP Virtual school from 5 to 30 July 2021. The school engages postgraduate students for a period of four weeks on research projects under the supervision of active research scientists. Each project addresses one or more open questions in order to expose students to the frontier of scientific cross-disciplinary research in several fields (statistical physics, systems ecology, quantitative economics, dynamical systems, information and large deviation theory, and neural networks). This provides a first hand experience of “research in action”, where asking the right questions is at least as important as finding the right answers. Many previous students have found this a life changing experience that transformed their view of science as an activity and as a possible career. The list of projects: 1. Stability of ecosystems with a core-periphery structure 2. The evolution of income or wealth distribution with higher order autoregressive processes 3. Exploring the Connections between Information Theory and Ergodicity Economics Through the Lens of Inequality Measurement 4. Growth incidence curves in reallocating geometric Brownian motion 5. Optimal allocation and risk parity 6. Time-average based saving versus Ensemble-average based saving and the evolution of wealth distribution 7. Learning random dynamical systems from data 8. Explainability and rationalization in decision theory: a coding theory approach 9. Beyond Rational Herding 10. Verifying interaction among different types of discrete events by using the multivariate Hawkes process 11. Anomalous diffusion in random dynamical systems 12. The trade-off between profit and time constraints and market impact 13. Large deviation theory in diluted random matrices 14. Tackling Quantum Many-Body Systems with Artificial Neural Networks 15. Experiments in ergodicity 16. Epidemic spreading models in the presence of feedback   Supervisors include LML Fellows and colleagues from the ICTP and the International School for Advanced Studies (SISSA). Students will also attend a series of scientific lectures and a scientific writing course, and the School will culminate with student presentations of their research. Project Supervisors: A.
