by Fabrizio Lillo 11 Apr '19

11 Apr '19

Dear Colleagues, a special sessions’ stream entitled Networks, Big Data, and Artificial Intelligence in Economics, Finance, and Social Sciences will take place during the AMASES Annual Conference, which will be held in Perugia on September 9-11, 2019 (http://amases2019.unipg.it). The special sessions’ stream focuses on the emerging multidisciplinary study of the interconnections in finance and social science, which brings with it the necessity to deal with the growing amount of data available. A special emphasis is given to latest advances in artificial intelligence and machine learning, which are expected to have disruptive impact in economic, financial, and social data modeling. The stream intends to foster the dialogue between academics, regulators, and practitioners. Theoretical and empirical papers are welcome. Topics include but are not limited to: - contagion in social, economic, and financial networks - network modeling of financial time-series - big data approach to financial, economic, and social modeling - artificial intelligence and machine learning in social, economic, and financial systems It is a great pleasure to invite you to submit an extended abstract. To be considered for the stream, please submit your abstract by specifying in the filename the stream code and the appropriate session, namely - Networks (NBDAI-NW) - Big Data (NBDAI-BD) - Artificial Intelligence (NBDAI-AI) in the file name. For example, for a paper in the Networks session use the file name (NBDAI-NW-[surname of author who will present the paper].pdf). Please refer to the official web page of the conference for further details on the submission. Important dates: May 1, 2019: deadline for abstract submission June 10, 2019: notification of acceptance June 17, 2019: early registration July 1, 2019: late registration For information, please contact: Giacomo Bormetti (giacomo.bormetti(a)unibo.it) Fabrizio Lillo (fabrizio.lillo(a)unibo.it) Michele Tumminello (michele.tumminello(a)unipa.it) We are looking forward to meeting you in Perugia.

Seminar Blanka Horvath in Padova (16/04/'19)
by Giorgia Callegaro 11 Apr '19

11 Apr '19

Dear all, I invite you to the seminar "Deep learning volatility", that will be given by Dr. Blanka Horvath (King's College - Londra), next Tuesday at 11.30, in room 2BC30 of the Mathematics Department in Padova. The abstract follows: * Abstract: We present a consistent neural network based calibration method for a number of volatility models-including the rough volatility family-that performs the calibration task within a few milliseconds for the full implied volatility surface. The aim of neural networks in this work is an off-line approximation of complex pricing functions, which are difficult to represent or time-consuming to evaluate by other means. We highlight how this perspective opens new horizons for quantitative modelling: The calibration bottleneck posed by a slow pricing of derivative contracts is lifted. This brings several model families (such as rough volatility models) within the scope of applicability in industry practice. As customary for machine learning, the form in which information from available data is extracted and stored is crucial for network performance. With this in mind we discuss how our approach addresses the usual challenges of machine learning solutions in a financial context (availability of training data, interpretability of results for regulators, control over generalisation errors). We present specific architectures for price approximation and calibration and optimize these with respect different objectives regarding accuracy, speed and robustness. We also find that including the intermediate step of learning pricing functions of (classical or rough) models before calibration significantly improves network performance compared to direct calibration to data. The talk is based on joint work with A. Muguruza an M. Tomas, available here: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3322085 See you there (if interested!), Giorgia -- Giorgia Callegaro Assistant Professor Department of Mathematics - University of Padova Via Trieste 63 , I-35121 Padova - ITALY Tel: +39-0498271481 Fax: +39-0498271499 E-Mail: gcallega(a)math.unipd.it <https://webmail.math.unipd.it/horde3/imp/message.php?mailbox=Sent&index=598#> Personal web-page: https://sites.google.com/site/giogiocallegaro/Home

Seminario a Roma 1
by Faggionato, Alessandra 11 Apr '19

11 Apr '19

Luned' 15 Aprile avremo il seguente seminario in Aula di Consiglio (Dipartimento di Matematica, La Sapienza, Roma), alle ore 16.00: Speaker: Marco Romito (Universita' di Pisa). Title: Fluctuations for point vortices Abstract: The first part of the presentation is a short review of a statistical mechanics model of point vortices for the 2D Euler equations and their mean field limit. In the second part we outline a proof of Gaussian fluctuations from the mean field limit. The result holds on the torus, on the sphere and on bounded domains. This is a work in collaboration with Francesco Grotto (Scuola Normale Superiore, Pisa). saluti alessandra ************************************************* Prof. Alessandra Faggionato http://www1.mat.uniroma1.it/~faggionato/ Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome Office 5, Phone (0039) 06 49913252 *************************************************

Dear Colleagues, a special session entitled ‘Challenges in modelling sparse and noisy data’ will take place during the AMASES Annual Conference, which will be held in Perugia on September 9-11, 2019 (http://amases2019.unipg.it<http://amases2019.unipg.it/>). [http://amases2019.unipg.it/images/piazza4novembre.jpg]<http://amases2019.unipg.it/> AMASES 2019<http://amases2019.unipg.it/> amases2019.unipg.it 43 rd Annual Meeting of the AMASES Association for Mathematics Applied to Social and Economic Sciences Perugia, September 9-11, 2019. The meeting is organized both by the Department of Mathematics and Computer Science and the Department of Economics of the University of Perugia. As in the AMASES established tradition, the purpose of the meeting is to stimulate discussion among scholars and ... Topic of the session Far more than in the past, policy makers, investors, and data scientists are required to take decisions based on sparse and noisy data. Observations from heterogeneous sources, typically sampled at different frequencies, and contaminated by noise, need to be aggregated and analyzed jointly. This is customary in several economic applications, including macroeconomics, high-frequency finance, climate economics, and data science. Traditional mathematical and statistical methods can lead to misleading conclusions when these features are not properly accounted for. The objective of this session is to present the latest methodologies and to foster discussions among researchers from different fields. Theoretical and empirical papers are welcome. Topics include but are not limited to: - high-frequency time series modelling - mixed-frequency data modelling in economic and social sciences - dimensionality reduction and factor analysis - sparse data modelling - noisy data filtering and smoothing It is a great pleasure to invite you to submit an extended abstract. To be considered for the stream, please submit your abstract by specifying the stream code (MSND) in the file name (MSND-[surname of author who will present the paper].pdf). Please refer to the official web page of the conference for further details on the submission. Important dates: May 1, 2019: deadline for abstract submission June 10, 2019: notification of acceptance June 17, 2019: early registration July 1, 2019: late registration For information, please contact: Giacomo Bormetti (giacomo.bormetti(a)unibo.it) Giuseppe Buccheri (giuseppe.buccheri(a)sns.it) Fabrizio Lillo (fabrizio.lillo(a)unibo.it) We are looking forward to meeting you in Perugia.
