Dear colleagues, you are all invited to participate in the following seminar organized by QFinLab - Department of Mathematics, Politecnico di Milano. Wednesday, 5 March 2025, 12.00-13.00 Seminar room, third floor, building 14, Via Bonardi 9, Milano (Leonardo Campus) Katia Colaneri (Università di Roma Tor Vergata) Title: Expect the worst! Optimal emission abatement under tax policy uncertainty and stochastic differential games. Abstract: We study the problem of a profit maximizing electricity producer who has to pay carbon taxes and who decides on investments into technologies for the abatement of CO emissions in an environment where carbon tax policy is random and where the investment in the abatement technology is divisible, irreversible and subject to transaction costs. We consider two approaches for modelling the randomness in taxes. First we assume a precise probabilistic model for the tax process, namely a pure jump Markov process (so-called tax risk); this leads to a stochastic control problem for the investment strategy. Second, we analyze the case of an uncertainty-averse producer who uses a differential game to decide on optimal production and investment. We carry out a rigorous mathematical analysis of the producer's optimization problem and of the associated nonlinear PDEs in both cases. Numerical methods are used to study quantitative properties of the optimal investment strategy. We find that in the tax risk case the investment in abatement technologies is typically lower than in a benchmark scenario with deterministic taxes. However, there are a couple of interesting new twists related to production technology, divisibility of the investment, tax rebates and investor expectations. In the stochastic differential game on the other hand an increase in uncertainty might stipulate more investment. Next seminar: Claudio Fontana (Università di Padova), 2 April 12.00.

Special issue of "Mathematical Finance" on "Climate and Nature Risk in Mathematical Finance" (fwd)
by Tiziano Vargiolu 25 Feb '25

25 Feb '25

Apologies for cross-postings. ----------------------- Special Issue on Climate and Nature Risk in Mathematical Finance Guest Editors: Andrea Macrina & Peter Tankov New extended deadline for submissions: 30 April 2025 The urgency and complexity of the climate crisis call for contributions from many scientific domains. In finance, modelling challenges posed by the environmental transition and by the climate change and nature-related risks call for inter- and transdisciplinary approaches, based on a multitude of data sources and long-term projections taking into account deep uncertainty. The mathematical finance community, which has developed robust systematic approaches to financial modelling and risk management, is well placed to address these challenges and has already made numerous quantitative contributions to the field of green finance. Mathematical Finance will dedicate a Special Issue to Mathematical Finance for Climate and Nature to further emphasise this area of research. Submissions to the Special Issue should develop and apply novel mathematical and statistical methods to financial and economic problems arising in the field of green finance and meet the editorial standards of Mathematical Finance as detailed in the aims and scope statement of the journal. Submissions with a policy or industry perspective are encouraged. We invite in particular the submission of original research articles on the following topics: * Assessment of climate and nature-related risks and uncertainties in financial systems; climate stress testing. * Study of transmission channels of physical risks, transition risk and nature-related risks to asset prices, portfolios and the stability of the financial system. * Optimal policies and incentives for environmental transition and adaptation of the economy, from the central planner perspective and in decentralised systems. * Optimal design and study of financial and insurance products, including derivative products, for managing climate and nature-related risks and for financing the environmental transition and adaptation. * Design and study of transition scenarios; quantification of scenario uncertainty * Net zero investment: quantitative methodologies for constructing net-zero-aligned portfolios and portfolios with positive impact on nature and biodiversity. * Study of innovative datasets and numerical methods, including AI-based methods, in support of the above topics. * Design of medium and long-term risk management methods accounting for potential policy changes and systemic alterations of market structures and stability. * Impact of climate and nature risks on emerging markets and developing economies. Please submit your contributions through the journal’s web submission portal before 30 April 2025. Please indicate in your submission that it is intended for the ‘Special Issue on Climate and Nature Risk in Mathematical Finance’. All submissions will undergo the usual review process for the journal. -- Peter Tankov Professor of quantitative finance, ENSAE, IP Paris Phone: +33 1 70 26 68 73 Email: peter.tankov(a)ensae.fr https://sites.google.com/site/petertankov https://www.parc-research.org/ https://pladifes.institutlouisbachelier.org/

Seminar Ziyi Song @ Unimib
by Federico Camerlenghi 25 Feb '25

25 Feb '25

Dear all, we are glad to announce the next DEMS seminar in Statistics: *Wednesday, 5th March 2025* *Time 12.00*, Seminar room 2104, Department of Economics, Management and Statistics (DEMS) Building U7, second floor, University of Milano - Bicocca The speaker is Ziyi Song (University of California, Irvine). *TITLE:* Clustering computer-mouse tracking data with informed hierarchical shrinkage partition priors *ABSTRACT:* Mouse-tracking data, which record computer mouse trajectories while participants perform an experimental task, provide valuable insights into subjects’ underlying cognitive processes. Neuroscientists are interested in clustering the subjects’ responses during computer mouse-tracking tasks to reveal patterns of individual decision-making behaviors and identify population subgroups with similar neurobehavioral responses.These data can be combined with neuroimaging data to provide additional information for personalized interventions. In this article, we develop a novel hierarchical shrinkage partition (HSP) prior for clustering summary statistics derived from the trajectories of mouse-tracking data. The HSP model defines a subjects’ cluster as a set of subjects that gives rise to more similar (rather than identical) nested partitions of the conditions. The proposed model can incorporate prior information about the partitioning of either subjects or conditions to facilitate clustering, and it allows for deviations of the nested partitions within each subject group. These features distinguish the HSP model from other bi-clustering methods that typically create identical nested partitions of conditions within a subject group. Furthermore, it differs from existing nested clustering methods, which define clusters based on common parameters in the sampling model and identify subject groups by different distributions. We illustrate the unique features of the HSP model on a mouse tracking dataset from a pilot study and in simulation studies. Our results show the ability and effectiveness of the proposed exploratory framework in clustering and revealing possible different behavioral patterns across subject groups. The paper has been published on Biometrics. <https://academic.oup.com/biometrics/article/80/4/ujae124/7850951?login=true> Best wishes, Federico Camerlenghi

Abstract: Simulation-based inference (SBI) is the preferred framework for estimating parameters of intractable models in science and engineering. A significant challenge in this context is the large computational cost of simulating data from complex models, and the fact that this cost often depends on parameter values. We therefore propose cost-aware SBI methods which can significantly reduce the cost of existing sampling-based SBI methods, such as neural SBI and approximate Bayesian computation. This is achieved through a combination of rejection and self-normalised importance sampling, which significantly reduces the number of expensive simulations needed. Our approach is studied extensively on models from epidemiology to telecommunications engineering, where we obtain significant reductions in the overall cost of inference. Keywords: simulation-based inference, approximate Bayesian computation, neural posterior estimation, neural likelihood estimation, importance sampling Best, Massimiliano on the behalf of the OWABI Organisers ------ Dr. Massimiliano Tamborrino Reader and WIHEA Fellow Department of Statistics University of Warwick https://warwick.ac.uk/tamborrino

[CfP] - International Workshop on Trustworthiness and Reliability in Neurosymbolic AI - IJCNN2025
by Lorenzo Di Rocco 21 Feb '25

21 Feb '25

[Apologies if you receive multiple copies of this CFP] Call for Papers - International Workshop on Trustworthiness and Reliability in Neurosymbolic AI @ IJCNN2025 July 5th, 2025, Rome, Italy https://sites.google.com/view/trns-ai ABOUT Neurosymbolic AI is a new growing trend that has been able to merge the recent advances in AI through deep learning with logic and rule-based methods. The application of neurosymbolic AI seems to be spreading across many contexts, from image classification to Visual Question Answering. It has an expressive and semantic power that is not usually provided by classical deep learning. In addition, it has great potential in explainability, due to the logic-based methodologies that are a strong component of this context. These capabilities are only a starting point in XAI, they need to be explored in detail to facilitate the interpretability of whole models, in any part of them and not only in terms of the natural relationships that can be discovered. This workshop will focus on two main aspects: 1. Gives the possibility to extend the exploration of the explainability in multiple contexts, developing and adapting techniques that can be useful to relate classical deep learning approaches to their symbolic extensions. 2. Opens to the possibility to extend the understanding of neurosymbolic models to deep aspects of AI. These two concepts lead to the trustworthiness and reliability of the new trend of Neurosymbolic AI, increasing the confidence of end-users in choosing and believing in these methodologies for computer-aided applications. Topics of interest include, but are not limited to: * Soft Computing methodologies * Symbolic and Neurosymbolic AI * Logic and Rule-based methods * AI methods for explainability, interpretrability and reliability * Resilient AI models * From wide to task-specific methodologies * Machine Learning and Deep Learning based AI methodologies * Data-driven decision-making * Multimodal Learning strategies * Scalability and optimization of intelligent systems * Generative AI and applications GREAT EVENT! XAI CHALLENGE FOR PASSIONATE! The workshop is growing fast and organizers are happy to announce that a challenge has been launched for all passionate students and researchers!
