Seminario di Ivailo Hartarsky alla Sapienza
by Faggionato, Alessandra 09 Dec '24

09 Dec '24

Buongiorno, la prossima settimana Ivailo Hartarsky (ENS, Lione) sarà ospite del Dipartimento di Matematica dell'Università La Sapienza. Lunedì 16 terrà un seminario. Sotto trovate i dettagli. Grazie Saluti Alessandra %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% When: Monday 16 December, 16:00. Room: Sala di Consiglio, Department of Mathematics, Sapienza University of Rome Speaker: Ivailo Hartarsky (ENS, Lyon) Title: Catalan percolation Abstract: In Catalan percolation, one declares the edges {i,i+1}, for integer i, *occupied* and each edge {i,j} with j> i+1 *open* independently with probability p. For k> i+1, we recursively define {i,k} to be *occupied*, if {i,k} is open and both {i,j} and {j,k} are occupied for some j in {i+1,...,k-1}. The model was introduced by Gravner and Kolesnik in the context of polluted bootstrap percolation, but is tightly linked with Catalan structures and oriented percolation. We establish that the critical parameter of the model is strictly between the natural lower and upper bounds given by 1/4 and the critical probability of oriented site percolation on Z^2 respectively. The most challenging part of the proof is a strict inequality for the critical parameter of an oriented percolation model with non-decaying infinite range dependencies, not relying on the Aizenman--Grimmett argument for essential enhancements. The talk is based on joint work with Eleanor Archer, Brett Kolesnik, Sam Olesker-Taylor, Bruno Schapira and Daniel Valesin available at https://arxiv.org/abs/2404.19583. -- ************************************************* Prof. Alessandra Faggionato https://www1.mat.uniroma1.it/people/faggionato/ Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome Office 123, first floor *************************************************

Seminari Padova - Pablo Lopez Rivera e Nicolas Agote
by alekos.cecchin＠unipd.it 06 Dec '24

06 Dec '24

Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (13 Dicembre) in aula 2BC30 (Torre Archimede, Università di Padova) ci saranno due seminari per il ciclo di seminari in Probabilità e Finanza di: 1) Pablo López Rivera (Université Paris Cité) <https://www.ljll.fr/lopezrivera/> https://www.ljll.fr/lopezrivera/ Title: Functional inequalities in the discrete setting and the Poisson-Föllmer Process Date: December 13, 2024, at 14:30, room 2BC30 Abstract: Functional inequalities are a ubiquitous tool in probability, since they help us quantify the convergence to equilibrium of ergodic Markov processes and imply good concentration properties. In the continuous setting, the Gaussian measure is a central object, since it satisfies both a Poincaré and a log-Sobolev inequality. In particular, Caffarelli's contraction theorem states that the optimal transport map pushing forward the Gaussian towards a measure which is more log-concave than it is 1-Lipschitz, a fact that allows us to extend these inequalities to those measures. Can we prove an analogous result in the discrete setting if we replace the Gaussian by the Poisson distribution? The type of measures that can arise as a pushforward of a discrete distribution is very limited; in addition, the lack of a chain rule in the discrete setting hinders the argument used in the continuous setting. In the first part of the talk, I will show how these obstacles can be overcome via a stochastic proof based on an entropy-minimizing process constructed by Klartag and Lehec, which we call the Poisson-Föllmer process. In the second part of the talk I will also use this process to give a stability result for Wu's log-Sobolev inequality, the Poissonan analog of the Gaussian one.. 2) Nicolas Agote (Universidad de Buenos Aires) Title: The potential method for community detection Date: December 13, 2024, at 15:30, room 2BC30 Abstract: The Stochastic Block Model (SBM) is a random graph model where nodes are (randomly) partitioned into classes, or communities, which share a common label, and edges are (randomly) added between each pair of nodes depending on their community membership. It is a very popular model to study the community detection problem, where the aim is to predict the communities given a sample graph. In this talk we will explore the potential estimators, which exploit information obtained via random walks, specifically expected first visit times to some subset of revealed nodes, to predict the community structure. We will show that they allow for strongly consistent and efficient estimations, particularly for small subsets of nodes. This work has been done in collaboration with Inés Armendáriz (UBA), Pablo Ferrari (UBA), and Florencia Leonardi (USP). Vi aspettiamo numerosi!

Seminars in Statistics at Collegio Carlo Alberto - S. Pulido (ENSIIE) and K. Ray (Imperial College London)
by Matteo Giordano 06 Dec '24

06 Dec '24

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.google.com/url?q=https://www.carloalberto.org/events/category/s…> Venerdì 13/12/2024, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente doppio seminario: ------------------------------------------------ 11.00-12.00 Speaker: Sergio Pulido (ENSIIE) Title: Polynomial Volterra processes Abstract: Recent studies have extended the theory of affine processes to the stochastic Volterra equations framework. In this talk, I will describe how the theory of polynomial processes extends to the Volterra setting. In particular, I will explain the moment formula and an interesting stochastic invariance result in this context. Potential applications to fractional volatility models will be discussed. This is joint work with Eduardo Abi Jaber, Christa Cuchiero, Luca Pelizzari and Sara Svaluto-Ferro. 12.00-13.00 Speaker: Kolyan Ray Title: Bayesian nonparametric inference in a McKean-Vlasov model Abstract: We study nonparametric estimation of the interaction term in a McKean-Vlasov model where noisy observations are drawn from the nonlinear parabolic PDE arising in the mean-field limit as the number particles grows to infinity. In this model, the long-time invariant state can be uninformative about the interaction potential. We therefore show that under certain regularity conditions on the initial state, the short-time behaviour of this system contains sufficient information to consistently recover the interaction potential using Gaussian process priors. This involves establishing a stability-type estimate for this PDE to solve the resulting inverse problem. ------------------------------------------------ Sarà possibile il seminario anche in streaming: chiunque volesse collegarsi è pregato di inviare una email entro *mercoledì 11/12/2024 * a matteo.giordano(a)unito.it <mailto:matteo.giordano@unito.it> Il webinar è organizzato dalla "de Castro" Statistics Initiative (www.carloalberto.org/stats <http://www.carloalberto.org/stats>) in collaborazione con il Collegio Carlo Alberto.

Seminario PRISMA oggi
by Francesco Caravenna 03 Dec '24

03 Dec '24

Seminari on-line del gruppo UMI - PRISMA (http://www.umi-prisma.polito.it/) Ricordiamo che oggi, martedì 3 dicembre 2024, Sonia Mazzucchi e Stefano Bonaccorsi (Università di Trento) ci parleranno di Passeggiate casuali sul piano complesso ed equazioni del calore di ordine superiore al secondo con il seguente orario: 16:00 Primo seminario 16:30 Pausa e discussione 16:45 Secondo seminario 17:15 Conclusione e discussione Trovate di seguito il riassunto. I seminari verranno trasmessi via Zoom al seguente link: https://uniroma1.zoom.us/j/88679569146 Meeting ID: 886 7956 9146 Vi aspettiamo numerosi! Valentina Cammarota e Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Sonia Mazzucchi (Università di Trento) e Stefano Bonaccorsi (Università di Trento) TITOLO: Passeggiate casuali sul piano complesso ed equazioni del calore di ordine superiore al secondo RIASSUNTO: La celebre formula di Feynman-Kac, che fornisce una rappresentazione della soluzione dell'equazione del calore in termini di un integrale rispetto alla misura di Wiener, non può essere generalizzata al caso in cui il laplaciano, o più in generale l'operatore ellittico del secondo ordine, è sostituito da un operatore di ordine superiore a 2. In altre parole per tale classe di equazioni differenziali di ordine elevato non è possibile costruire un processo stocastico che svolga lo stesso ruolo giocato dal moto Browniano per l'equazione del calore. Nella prima parte del seminario si illustreranno dapprima le ragioni di questo risultato no-go per poi descrivere un possibile metodo per aggirarlo tramite la costruzione di opportune successioni di passeggiate casuali nel piano complesso. Nella seconda parte del seminario si descriveranno ulteriori applicazioni e generalizzazioni di tale tecnica. In particolare si illustrerà la costruzione di un calcolo stocastico associato alla successione di passeggiate casuali e la dimostrazione di formule di Feynman-Kac per PDE di ordine elevato, anche nel caso di derivate di tipo frazionario. %%%%%%%%%%%%%%%%%%%%%%%%%%%% I seminari PRISMA hanno un formato di "colloquium" per creare un'occasione di scambio e discussione con tutta la comunità dei probabilisti e statistici italiani. Ogni giornata comprende due relatori che tengono due seminari di 30 minuti strettamente connessi, per presentare alla comunità una prospettiva sul proprio ambito di ricerca. Da quest'anno le registrazioni dei seminari vengono pubblicate sul canale YouTube dell'UMI: https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb %%%%%%%%%%%%%%%%%%%%%%%%%%%%

Algebra meets probability: workshop
by Cipriani, Alessandra 02 Dec '24

02 Dec '24

Dear colleagues, registration is now open for the workshop "Algebra meets probability" taking place between March 31 and April 2, 2025 at EURANDOM at Eindhoven University of Technology. There is a natural and well-known connection between particle physics and representation theory via Grassmannian and Lie algebras, going back to Wigner. Specific algebraic structures, such as Virasoro algebras, are used in lattice models to describe symmetries and conservation laws. These structures help in understanding the behavior of systems at a microscopic level and in deriving macroscopic properties from microscopic rules. In recent years there has been tremendous progress in connecting these two approaches and expressing observables like k-point correlation functions in interacting particle systems in terms of algebraic quantities, for example as fermionc and bosonic variables. This event aims to bring together leading experts and researchers in the field to share their knowledge, insights, and recent advancements. The workshop will provide a platform for in-depth discussions and collaborative learning, fostering an environment where participants can exchange ideas and develop new perspectives on the interplay between these two fascinating areas of study. Speakers: David Adame-Carrillo (Aalto University) Francesca Arici (Leiden University) Chiara Boccato (University of Pisa) Martijn Caspers (TU Delft) Nicholas Crawford (Technion, Haifa) Margherita Disertori (Bonn University) Tyler Helmuth (Durham University) Bas Janssens (TU Delft) Kalle Kytölä (Aalto University) Yves Le Jan (NYU Abu Dhabi) Franz Merkl (TU München) Eveliina Peltola (TBC) (Aalto University) Silke Rolles (TU München) Walter van Suijlekom (Radboud University Nijmegen) Pierre Tarrès (NYU Shanghai) More details and the registration can be found on the conference website.<https://www.eurandom.tue.nl/event/algebra-meets-probability/> There is no registration fee and the possibility to present a poster. With best regards, Alessandra Cipriani Wioletta Ruszel

28 Nov '24

Dear Colleagues, as part of the Visiting Professors program of the Master's Degree in Stochastics and Data Science at the University of Torino (full program available at https://www.master-sds.unito.it/go/visiting) we are pleased to announce the following short course: ——————————————————— Kolyan RAY (Imperial College London) POSTERIOR ASYMPTOTICS IN BAYESIAN NONPARAMETRICS This mini-course will cover an introduction into the asymptotic theory for Bayesian nonparametric procedures. This provides a useful tool to understand how prior choices can affect the statistical performance of the Bayes method in high or infinite dimensional models. We will cover the notion of posterior consistency and convergence rates, using Gaussian process priors as a canonical example. At the end, we will also touch on recent extensions of such theory to variational Bayes, which provides a scalable posterior approximation algorithm. ——————————————————— The course will be held exclusively in-person, according to the following schedule: - Tue Dec 10, h. 9.15-11.15 - Wed Dec 11, h. 11.15-13.00 - Thu Dec 12, h. 9.15-11.15 - Thu Dec 12, h. 14.00-16.00 Course location: Room 30, third floor, Corso Unione Sovietica 218/bis, 10134, Torino.

Seminario Padova - Alex Delalande

28 Nov '24

Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (29 Novembre) alle ore 14:30 in aula 2BC30 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: Alex Delalande (EPFL Losanna) https://alex-delalande.github.io Title: Sharper Exponential Convergence Rates for Sinkhorn's Algorithm in Continuous Settings Date: November 29, 2024, at 14:30, room 2BC30 Abstract: In this talk, I will present recent results I obtained in collaboration with Lénaïc Chizat and Tomas Vaškevičius regarding the convergence rate of Sinkhorn's algorithm for solving entropy-regularized optimal transport problems, in the context where at least one of the probability measures, say \mu, admits a density over \R^d. For a semi-concave cost function bounded by c∞ and a regularization parameter λ>0, we obtained exponential convergence guarantees on the dual sub-optimality gap with contraction rates that are polynomial in λ/c∞. This represents an exponential improvement over the known contraction rate 1−Θ(exp(−c∞/λ)) achievable via Hilbert's projective metric. Specifically, we proved a contraction rate value of 1−Θ(λ²/c²∞) when has a bounded log-density. In some cases, such as when is log-concave and the cost function is c(x,y)=−⟨x,y⟩, this rate improves to 1−Θ(λ/c∞). The latter rate matches the one that we derived for the transport between isotropic Gaussian measures, indicating tightness in the dependency in λ/c∞. Our results are fully non-asymptotic and explicit in all the parameters of the problem. Vi aspettiamo numerosi!

by Michele Salvi 26 Nov '24

26 Nov '24

Dear all, On Tuesday, December 3rd, at 14h00 in Aula Dal Passo of Tor Vergata Math Department, RoMaDS (https://www.mat.uniroma2.it/~rds/events.php) will host Carlo Ciliberto (University College London) with the seminar “Operator World Models for Reinforcement Learning” Abstract: Policy Mirror Descent (PMD) is a powerful and theoretically sound methodology for sequential decision making. However, it is not directly applicable to Reinforcement Learning (RL) due to the inaccessibility of explicit action-value functions. We address this challenge by introducing a novel approach based on learning a world model of the environment using conditional mean embeddings. Leveraging tools from operator theory we derive a closed-form expression of the action-value function in terms of the world model via simple matrix operations. Combining these estimators with PMD leads to POWR, a new RL algorithm for which we prove convergence rates to the global optimum. Preliminary experiments in finite and infinite state settings support the effectiveness of our method. We encourage in-person partecipation.

Seminario PRISMA mar 3 dic 2024
by Francesco Caravenna 19 Nov '24

19 Nov '24

Seminari on-line del gruppo UMI - PRISMA (http://www.umi-prisma.polito.it/) I seminari PRISMA hanno un formato di "colloquium" per creare un'occasione di scambio e discussione con tutta la comunità dei probabilisti e statistici italiani. Ogni giornata comprende due relatori che tengono due seminari di 30 minuti strettamente connessi, per presentare alla comunità una prospettiva sul proprio ambito di ricerca. Da quest'anno le registrazioni dei seminari vengono pubblicate sul canale YouTube dell'UMI: https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb Il prossimo appuntamento è per martedì 3 dicembre 2024. I relatori saranno Sonia Mazzucchi e Stefano Bonaccorsi (Università di Trento) che ci parleranno di Passeggiate casuali sul piano complesso ed equazioni del calore di ordine superiore al secondo con il seguente orario: 16:00 Primo seminario 16:30 Pausa e discussione 16:45 Secondo seminario 17:15 Conclusione e discussione Trovate di seguito il riassunto. I seminari verranno trasmessi via Zoom al seguente link: https://uniroma1.zoom.us/j/88679569146 Meeting ID: 886 7956 9146 Vi aspettiamo numerosi! Valentina Cammarota e Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Sonia Mazzucchi (Università di Trento) e Stefano Bonaccorsi (Università di Trento) TITOLO: Passeggiate casuali sul piano complesso ed equazioni del calore di ordine superiore al secondo RIASSUNTO: La celebre formula di Feynman-Kac, che fornisce una rappresentazione della soluzione dell'equazione del calore in termini di un integrale rispetto alla misura di Wiener, non può essere generalizzata al caso in cui il laplaciano, o più in generale l'operatore ellittico del secondo ordine, è sostituito da un operatore di ordine superiore a 2. In altre parole per tale classe di equazioni differenziali di ordine elevato non è possibile costruire un processo stocastico che svolga lo stesso ruolo giocato dal moto Browniano per l'equazione del calore. Nella prima parte del seminario si illustreranno dapprima le ragioni di questo risultato no-go per poi descrivere un possibile metodo per aggirarlo tramite la costruzione di opportune successioni di passeggiate casuali nel piano complesso. Nella seconda parte del seminario si descriveranno ulteriori applicazioni e generalizzazioni di tale tecnica. In particolare si illustrerà la costruzione di un calcolo stocastico associato alla successione di passeggiate casuali e la dimostrazione di formule di Feynman-Kac per PDE di ordine elevato, anche nel caso di derivate di tipo frazionario. %%%%%%%%%%%%%%%%%%%%%%%%%%%%

Reminder: Bertram Duering in Sapienza
by Enrico Scalas 18 Nov '24

18 Nov '24

Car* collegh*, mi permetto di ricordare il seguente annuncio inviato più di un mese fa. Il seminario si terrà domani. -- Il 19 novembre 2024, in aula 24 del Dipartimento di Scienze Statistiche, Sapienza, Università di Roma, alle ore 14, il Prof. Bertram Düring della University of Warwick, Mathematics Institute terrà un seminario dal titolo From interacting agents to emerging patterns in economics and sociology Riassunto: Real-world systems in economics and sociology often consist of a large number of interacting agents that may form patterns or develop a collective behaviour. Typical applications include wealth and income distribution in an economy and opinion formation in a society. Mathematical techniques originating from statistical mechanics can be successfully developed further to model such systems and obtain mesoscopic and macroscopic descriptions of the microscopic dynamics. Such approaches frequently lead to generalisations of the classical Boltzmann equation for gas dynamics and associated limit partial differential equations. In this talk I will discuss different kinetic models for wealth distribution and opinion formation, and present analytical and numerical results. Tutte le persone interessate sono invitate a partecipare. Chi fosse interessato a partecipare a distanza, per favore, mi scriva a: enrico.scalas(a)uniroma1.it -- Cordiali saluti, Enrico Scalas

Seminario Davide Bignamimi - Politecnico di Milano - 27 Novembre 2024
by Luca Scarpa 18 Nov '24

18 Nov '24

Si segnala il seguente seminario a tutti gli interessati. Mercoledì 27 Novembre 2024, ore 11:00. Aula Seminari III Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Davide Bignamini, Università degli Studi dell'Insubria. Title: Strong uniqueness for SPDEs and regularity of Kolmogorov equations. Abstract: Pathwise uniqueness plays a crucial role in the investigation of the existence of strong solutions to Stochastic Differential Equations (SDEs) since the seminal result by Yamada and Watanabe in 1971, where they proved that weak existence and pathwise uniqueness imply strong existence. A few years later, Zvonkin introduced the so-called Zvonkin transformation, which allows to remove a drift term by means of a suitable change of coordinates using the Ito formula, and then applies the result of Yamada and Watanabe to construct strong solutions to a class of SDEs with rough drift coefficient. In recent years, these techniques have been extended to Stochastic Partial Differential Equations (SPDEs) . One of the main tools for proving pathwise uniqueness in infinite dimensions is the so-called Itô-Tanaka trick, which involves replacing the "bad" drift term with the solution to a suitable Kolmogorov equation. In this talk, we will examine these topics for a class of parabolic and hyperbolic SPDEs.

12 Nov '24

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *Exclusion Processes with non-reversible boundary: Hydrodynamics and Large Deviations* by *João Pedro Mangi* (*IMPA*) The seminar will take place on TUE, 19.11.2024 at *11:00 CET* in Aula Tricerri, Dipartimento di Matematica e Informatica "Ulisse Dini", Università degli Studi di Firenze, and streamed online at this link <https://meet.google.com/gji-phwo-vbg>. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass -------------------------------------------- *Abstract: We consider a family of exclusion processes defined on the discrete interval with weak boundary interaction that allows the creation and annihilation of particles on a neighborhood of radius L of the boundary under very general rates. We prove that the hydrodynamic equation is the heat equation with non-linear Robin boundary conditions. We present a particular choice of boundary rates for which we have multiple stationary solutions but for which it still holds the uniqueness of the solution of its hydrodynamic equation. We also prove the associated dynamical large deviations principle. Joint work with Claudio Landim and Beatriz Salvador.*

Giulia Livieri will give the first seminar. Wednesday, November 27, 2024, 1:30 - 2:30 PM CET, Sala del Consiglio Prof. Giulia Livieri, London School of Economics A Mean Field Game approach for pollution regulation of competitive firms Abstract: We develop a model based on mean-field games of competitive firms producing similar goods according to a standard AK model with a depreciation rate of capital generating pollution as a byproduct. Our analysis focuses on the widely-used cap-and-trade pollution regulation. Under this regulation, firms have the flexibility to respond by implementing pollution abatement, reducing output, and participating in emission trading, while a regulator dynamically allocates emission allowances to each firm. The resulting mean-field game is of linear quadratic type and equivalent to a mean-field type control problem, i.e., it is a potential game. We find explicit solutions to this problem through the solutions to differential equations of Riccati type. Further, we investigate the carbon emission equilibrium price that satisfies the market clearing condition and find a specific form of FBSDE of McKean-Vlasov type with common noise. The solution to this equation provides an approximate equilibrium price. Additionally, we demonstrate that the degree of competition is vital in determining the economic consequences of pollution regulation. Joint work with G. Del Sarto and M. Leocata. We look forward to meeting you in Pavia. Kind Regards, Giacomo Bormetti Giacomo Bormetti Department of Economics and Management, University of Pavia

Seminario CLIMATH 20 Novembre
by Marta Leocata 09 Nov '24

09 Nov '24

Cari colleghi, Il gruppo UMI-Climath è lieto di invitarvi a una serie di seminari, in presenza e online, dedicati ai recenti avanzamenti teorici nello studio dei modelli matematici della variabilità climatica e dei modelli che includono gli impatti socio-economici associati. Maggiori dettagli sono disponibili sul sito del gruppo Climath: https://sites.google.com/view/gruppo-umi-climath/seminari-ed-attività-del-g… <https://sites.google.com/view/gruppo-umi-climath/seminari-ed-attivit%C3%A0-…> Il Prossimo seminario si terrà in data Mercoledì 20 novembre 2024, alle ore 14:30, presso l’Aula 1101 (D’Antoni), Dipartimento di Matematica, Tor Vergata, Roma, oppure online tramite Teams (richiesta registrazione al link: https://forms.gle/kuPKvHqLDP4RTLj4A) Ecco il programma: 14:30 - Valerio Lucarini (University of Leicester) Titolo: Detecting and Attributing Change in Climate and Complex Systems: Foundations, Green's Functions, and Nonlinear Fingerprints Abstract: Detection and attribution (D&A) studies are cornerstones of climate science, providing crucial evidence for policy decisions. Their goal is to link observed climate change patterns to anthropogenic and natural drivers via the optimal fingerprinting method (OFM). We show that response theory for nonequilibrium systems offers the physical and dynamical basis for OFM, including the concept of causality used for attribution. Our framework clarifies the method's assumptions, advantages, and potential weaknesses. We use our theory to perform D&A for prototypical climate change experiments performed on an energy balance model and on a low-resolution coupled climate model. We also explain the underpinnings of degenerate fingerprinting, which offers early warning indicators for tipping points. Finally, we extend the OFM to the nonlinear response regime. Our analysis shows that OFM has broad applicability across diverse stochastic systems influenced by time-dependent forcings, with potential relevance to ecosystems, quantitative social sciences, and finance, among others. 15:20 - Discussione 15:30 - Gianmarco Del Sarto (Technische Universität Darmstadt) Titolo: Some Perspective on Climate Change through Energy Balance Models Abstract: In this seminar, I will present how Energy Balance Models (EBMs) can be used to explore climate change dynamics. The first part focuses on ongoing research that investigates a fast-slow system where solar radiation acts as the fast component, while a zero-dimensional EBM describes the slow component. This model exhibits mathematical parallels with the seminal stochastic EBM inspired by Hasselmann's proposal, and we explore these similarities in terms of deterministic limits, fluctuations, and large deviations. In the second part, if time allows, I will discuss a completed research project that extends the analysis of 1D EBMs by introducing local instability effects and additive white noise. The model captures the super-greenhouse effect, a tropical feedback mechanism, and incorporates fast weather fluctuations as white noise. By studying the long-term behaviour of the model's invariant measure, we investigate the link between increased greenhouse gas concentrations and extreme weather events. 16:20 - Discussione 16:3 - Tavola Rotonda moderata da Piermarco Cannarsa Speriamo di vedervi numerosi, sia in presenza che online! Saluti, Marta Leocata (a nome del gruppo Climath)

Seminar by Joanna Michalak, Dr.
by monte＠uniroma2.it 09 Nov '24

09 Nov '24

Dear all, Dr. Joanna Michalak (Nicolaus Copernicus University in Torun, Poland) will give a seminar entitled "Integrated Approach to Sentiment Analysis: Optimizing Short Text Analysis Efficiency in the Context of Economics and Finance" on November 14th at 09:30 am in Room 5 at Macro Teaching Hub Engineering Area., Via del Politecnico, 1, University of Roma "Tor Vergata", Roma. The seminar can also be followed online by sending an email to roberto.monte(a)uniroma2.eu Abstract: Big social data (BSD) is widely used in the social sciences, particularly in economics and finance, where it is valued both for its explanatory insights and its predictive power. Predictive analyses leveraging BSD often focus on modeling the relationship between social media activity and stock market movements. The quality of these analyses relies on two main dimensions: (1) models that capture short-term dynamics and account for observed time-series properties, and (2) sentiment analysis methods that are specifically adapted to the unique vocabulary of finance and economics. This presentation addresses these two dimensions. In the first part, we explore a case study of Apple Inc., comparing the effectiveness of VAR, GARCH, and LSTM models for describing short-term interdependencies between social media sentiment and stock market behavior. The second part of the presentation focuses on the performance of various sentiment analysis methods selected to construct sentiment-based indices. This section aims to compare the efficiency and accuracy of different sentiment analysis methods when applied to short text data. The study emphasizes optimization of analysis efficiency by evaluating widely used datasets, such as Senti140. Several research questions guide this investigation: 1. Which sentiment analysis method is most effective in terms of accuracy and processing speed in financial data analysis? 2. Do advanced methods, such as deep learning models (e.g., BERT), outperform traditional lexicon-based techniques and classical machine learning algorithms? 3. What are the differences in sentiment analysis accuracy between general datasets like Senti140 and finance-specific datasets such as FinBERT? The issue of optimizing text data analysis methods remains an open aspect of this research. The ultimate objective of this study is to construct a dataset or lexicon specifically designed and recommended for financial data analysis.
