One World ABC - Till Hoffmann - September 29, 1.30pm UK time
by Massimiliano Tamborrino 26 Sep '22

26 Sep '22

Dear all, Season 4 of the One Word ABC Seminar https://warwick.ac.uk/oneworldabc is starting this week on Thursday the 29th September, 1.30pm UK time. The first speaker of the season will be Till Hoffman, who will talk about "Minimizing the Expected Posterior Entropy Yields Optimal Summary Statistics", with an abstract reported below. The link to join the talk is https://bristol-ac-uk.zoom.us/j/93353511660?pwd=MmFTNUR5QkFBeStlenNVemtZbzJ… Meeting ID: 933 5351 1660 Passcode: 406075 We are looking forward to seeing you there, Best regards, Massimiliano on the behalf of the One World ABC Organisers When: 29th September, 1.30pm UK time Speaker: Till Hoffmann <https://tillahoffmann.github.io/> (Harward T.H. Chan School of Publich Health) Title: Minimizing the Expected Posterior Entropy Yields Optimal Summary Statistics Abstract: Extracting low-dimensional summary statistics from large datasets is essential for efficient (likelihood-free) inference. We propose obtaining summary statistics by minimizing the expected posterior entropy (EPE) under the prior predictive distribution of the model. We show that minimizing the EPE is equivalent to learning a conditional density estimator for the posterior as well as other information-theoretic approaches. Further summary extraction methods (including minimizing the L² Bayes risk, maximizing the Fisher information, and model selection approaches) are special or limiting cases of EPE minimization. We demonstrate that the approach yields high fidelity summary statistics by applying it to both a synthetic benchmark as well as a population genetics problem. We not only offer concrete recommendations for practitioners but also provide a unifying perspective for obtaining informative summary statistics. Reference: T. Hoffmann and J.P. Onnela.

LUISS Seminar September 29 -- prof Cristensen, link
by Sara 22 Sep '22

22 Sep '22

Dear all, this is a gentle memo of the seminar by Soren Christensen, Uni-Kiel, September 29 at 12:30 e verterà su: *Nonparametric approaches to data-driven stochastic control* Abstract: One of the fundamental assumptions in stochastic control of continuous-time processes is that the dynamics of the underlying process are known. This is, however, usually obviously not fulfilled in practice. On the other hand, a rich theory for nonparametric estimation of the characteristics of continuous-time processes has been developed over the last decades. In this talk, we discuss how to bring together these two areas for developing purely data-driven strategies for stochastic control, which we explore for ergodic impulse and singular control problems. We compare the results with those of deep-Q learning algorithms.

Seminar of Prof. Eckhard Platen, on Friday 23 september, at 3pm (fwd)
by Tiziano Vargiolu 20 Sep '22

20 Sep '22

Dear all, on Friday 23 september, at 3pm , we will have the pleasure to host the seminar of Prof. Eckhard Platen from University of Sydney, who is visiting our math department during this week. The seminar will be in presence at the Department of Mathematics, University of Padova, room 702 (stair B, 7th floor at via Trieste 63, Padova) and available on Zoom at the following address: https://unipd.zoom.us/j/86350461357 Title and abstract of the presentation are here below. Modeling Long-Term Stock Market Dynamics via Entropy Maximization Eckhard Platen University of Technology Sydney Abstract: By assuming the existence of the growth optimal portfolio (GP) and maximizing the entropy for a hierarchically structured stock market, the paper derives the GP dynamics as those of time-transformed squared Bessel processes of dimension four. The average of each of their squared volatility components is shown to converge toward a common level. The initial values of basis security accounts turn out to be gamma-distributed. The risk-adjusted return of the GP is not depending on a savings account and can be significantly higher than classical assumptions allow to explain.
