Seminari di H.A.Mimun e G. Panizo a Roma, Univ. La Sapienza
by Faggionato, Alessandra 11 Dec '19

11 Dec '19

Buongiorno sotto trovate l'annuncio per due seminari che si terranno al Dipartimento di Matematica dell'Università La Sapienza a Roma la prossima settimana. grazie saluti alessandra ****************************************************************************************** *When*: Monday 16 December, 16:00 *Where*: Room B, Department of Mathematics, Sapienza University, Rome. *Speaker*: H.A. Mimun (Department of Mathematics, Sapienza University, Rome) *Title:* Percolation in the Miller-Abrahams random resistor network *Abstract: *The Miller-Abrahams random resistor network is used to study electron transport in amorphous solids. This resistor network is given by the complete random graph built on a marked homogeneous Poisson point process on R^d and each edge {x,y} is associated to a filament with conductance depending on the temperature, the distance between the points x,y and their associated marks. In this talk we consider the subgraph containing only edges with lower bounded conductances and, using the method of randomized algorithms developed by Duminil-Copin et al. and the renormalization argument proposed by Grimmett and Marstrand, we analyze the connection probabilities and the left-right crossings in appropriate regimes. These percolation properties are key ingredients for understanding the asymptotic behavior at low temperature of the effective conductivity of the Miller-Abrahams random resistor network. Joint work with Alessandra Faggionato (Sapienza University, Rome). ****************************************************************************************** *When*: Tuesday 17 December, 14:00 (sharp!) *Where:* Sala di Consiglio, Department of Mathematics, Sapienza University, Rome. *Speaker: *Gonzalo Panizo Garcia, IMCA, Lima, Perù *Title:* A self-interacting random walk *Abstract:* In 2011, Benjamini, Kozma and Schapira introduced a “balanced excited random walk” in the 4-dimensional lattice. In 2016, a similar model was studied by Peres, Schapira and Sousi in the 3-dimensional lattice. Here we generalize their constructions in the d-dimensional lattice, in the following way: if the walk visits a site for the first time, it makes a simple random walk step in the first d_1 dimensions, whereas if the site has been already visited, it makes a simple random walk step in the last d_2 coordinates. Both BKS and PSS proved transience in the non-overlapping case d=d_1+d_2, with d_1=d_2=4 (BKS) and d_1=1, d_2=3 (PSS). In this talk some result for the overlapping case (d_1+d_2>d) will be presented, in particular for d=4, d_1=2 and d_2=3. (Joint work with D. Camarena and A. Ramirez). -- ************************************************* 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 *************************************************

Seminario Antonio Lerario Roma Tor Vergata
by Anna Vidotto 06 Dec '19

06 Dec '19

I would like to announce the following talk that will be held on Thursday December 12th 2019, at 4:30 PM, in Aula Dal Passo of the Department of Mathematics, University of Rome Tor Vergata. Speaker: Antonio Lerario (SISSA Trieste) Title: Low-degree approximation of real singularities Abstract: In this talk I will discuss some recent results that allow to approximate a real singularity given by polynomial equations of degree $d$ (e.g. the zero set of a polynomial, or the number of its critical points of a given Morse index) with a singularity which is diffeomorphic to the original one, but it is given by polynomials of degree $O(d^{1/2}log d)$. The approximation procedure is constructive (in the sense that one can read the approximating polynomial from a linear projection of the given one) and quantitative (in the sense that the approximating procedure will hold for a subset of the space of polynomials with measure increasing very quickly to full measure as the degree goes to infinity). This is based on a combination of joint works with P. Breiding, D. N. Diatta and H. Keneshlou. — This talk is part of the activity of the MIUR Excellence Department Project CUP E83C18000100006 — —————— Anna Vidotto PostDoc Researcher Dipartimento di Matematica Università degli Studi di Roma Tor Vergata https://sites.google.com/view/annavidotto

Guido Consonni and Fabrizio Ruggeri ABS20 Directors Raffaele Argiento and Antonio Pievatolo ABS20 Executive Directors ------------------------------------------------------------------------ ******************************* * ABS20 * ******************************* Applied Bayesian Statistics School BAYESIAN CAUSAL INFERENCE Florence Center for Data Science, University of Florence Florence, Italy 8-12 June, 2020 Lecturer: Prof. Fan Li (Department of Statistical Science, Duke University, Durham, NC, USA) https://stat.duke.edu/people/fan-li The conference webpage is >>> http://www.mi.imati.cnr.it/conferences/abs20/index.html <<< Registration is now open to reserve a place (but payments are possible only from early January). Please note that the conference room allows only for a very limited number of participants. COURSE OUTLINE The aim of this course is to introduce the fundamental concepts and state-of-art methods for causal inference under the potential outcome framework. The lectures will be organized by the treatment assignment mechanisms. Topics will cover randomized experiments, observational studies with ignorable assignment mechanisms, natural experiments, sequential ignorable longitudinal treatments. Recent advances related to machine learning and more complex situations such as spatial-temporal treatments and interference will also be discussed. All methods will be illustrated via real case studies in health studies, economics and biology. Though the causal framework and most of the methods are independent of the inferential paradigm, an emphasis will be put on the Bayesian paradigm for inference. TENTATIVE PROGRAM See the daily program on the website. PRACTICAL INFORMATION The school will replicate the successful format of the previous years, and will feature lectures and practical sessions (run by a junior researcher), as well as participants' talks. It will start on Monday after lunch and end on Friday before lunch; Wednesday afternoon is free. Info on accommodation will appear soon on the website. Florence (Firenze) is easily accessible by train, airplane or car.

Seminario di Tyler Helmuth (Bristol) a Roma Tre, 12-12-2019

03 Dec '19

SEMINARIO Probabilita' Tyler Helmuth (University of Bristol) Titolo: Random spanning forests and hyperbolic symmetry Giovedi' 12 Dicembre 2019 ORE 10:00 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Largo San Leonardo Murialdo,1 - Pal.C - Aula 211 Abstract The arboreal gas is a probability measure that arises from conditioning the random subgraph given by Bernoulli(p) bond percolation to be a spanning forest, i.e., to contain no cycles. This conditioning makes sense on any finite graph G, and specializes to the uniform measure on spanning forests when p = 1/2. One is naturally lead to ask about the percolative properties of the arboreal gas, and this turns out to be a surprisingly rich question. I will discuss some results and conjectures about the arboreal gas, most of which are based on important relations between the arboreal gas and spin systems with hyperbolic symmetry. Based on joint work in progress with Roland Bauerschmidt, Nick Crawford, and Andrew Swan.

Economists For Future (fwd)
by Tiziano Vargiolu 02 Dec '19

02 Dec '19

Per completezza: c'e' una cosa molto importante che non viene detta sotto, ma nella procedura di firma si', ed e' questa: IMPORTANT: This open letter is open to everyone to sign, not just economists! Cordiali saluti a tutti ---------- Forwarded message ---------- Date: Mon, 02 Dec 2019 13:16:12 +0000 From: Luisa Jentsch <noreply(a)econ4future.org> Reply-To: info(a)econ4future.org To: Tiziano <vargiolu(a)math.unipd.it> Subject: Economists For Future Dear Tiziano, I write to introduce you to Economists for Future?s open letter that is calling on the economics community to raise its game and devise a more impactful contribution to tackling climate change. Economists for Future is an international student-led organisation with the aim to put pressure on the economics community to treat climate change like the emergency it is. While many economists have shown great academic leadership on this issue, the overall contribution from the community has not been commensurate with the magnitude of the problem. The shortage of climate change related articles in top journals is one such demonstration. For example, the most-cited journal in our discipline has never published an article on climate change [https://lists.econ4future.org/links/iJ9AW4JXP/PfQP6QyMO/aMbvBGRdzdg/YJmX2li…]. As the next generation of economists, as young people who will live through the most severe climate effects and as individuals with a deep belief in the power of good economics to make the world a better place, we feel an acute pressure to ?do more? that we are hoping you will share. We think economists have both a responsibility and an enormous opportunity to have an even greater contribution to help tackle this emergency. The open letter (attempts to) make the case for economists seizing this opportunity to provide the intellectual framework that enables a rapid decarbonisation that is coupled with a great leap in human progress. We would like to invite you to support this initiative by signing the letter, which you can do by filling out the form on our website. [https://lists.econ4future.org/links/iJ9AW4JXP/PfQP6QyMO/aMbvBGRdzdg/K8_4G0o…] And, if you agree with it, we would kindly ask you to share your support among your social and academic networks. If you have any questions about our initiative or the letter, we would love to hear from you ? at the end of the day, we are curious students that desire more from the discipline we want to dedicate our lives to. Kind Regards, Luisa Jentsch Economists For Future Website: econ4future.org [econ4future.org] Facebook [https://lists.econ4future.org/links/iJ9AW4JXP/PfQP6QyMO/aMbvBGRdzdg/CY-m9M0…] Instagram [https://lists.econ4future.org/links/iJ9AW4JXP/PfQP6QyMO/aMbvBGRdzdg/qHhHAzS…] Twitter [https://lists.econ4future.org/links/iJ9AW4JXP/PfQP6QyMO/aMbvBGRdzdg/zMI73YS…]

Seminario Prof. Claudio Macci

Il Prof. Claudio MACCI dell'Università di Roma Tor Vergata mercoledì 4 dicembre 2019 alle ore 16 nell'Aula E al III livello del Dipartimento di Matematica e Applicazioni dell'Università degli Studi di Napoli Federico II terrà un seminario dal titolo: Large deviations for risk measures in finite mixture models ABSTRACT Due to their heterogeneity, insurance risks can be properly described as a mixture of different fixed models, where the weights assigned to each model may be estimated empirically from a sample of available data. If a risk measure is evaluated on the estimated mixture instead of the (unknown) true one, then it is important to investigate the committed error. In this paper we study the asymptotic behaviour of estimated risk measures, as the data sample size tends to infinity, in the fashion of large deviations. We obtain large deviation results by applying the contraction principle, and the rate functions are given by a suitable variational formula; explicit expressions are available for mixtures of two models. Finally, our results are applied to the most common risk measures, namely the quantiles, the expected shortfall and the shortfall risk measure. Joint work with Valeria Bignozzi and Lea Petrella.

Avviso di Seminario, università di Trento Stochastic homogenization in amorphous media and applications to interacting particle systems and random resistor networks Giovedì 5 dicembre 2019 Luogo: Polo Ferrari 1, via Sommarive, 5 - Povo (TN) - Aula A221 Ore: 16:00 Relatore: Alessandra Faggionato (Università La Sapienza, Roma) Abstract: We consider random walks on marked simple point processes with symmetric jump rates and unbounded jump range. Examples are given by simple random walks on Delaunay triangulations or Mott variable range hopping in doped semiconductors. We present homogenization results for the associated Markov generators. As a first application, we obtain the hydrodynamic limit of the exclusion process given by multiple random walks as above, with hard–core interaction. As a second application, we derive a limit theorem for the effective conductivity of some classes of random resistor networks. This result together with a percolation-type analysis allows to derive the low temperature scaling behavior of conductivity in some classes of strongly disordered media.

Seminar Berthet @Bocconi
by Giacomo Zanella 25 Nov '19

25 Nov '19

We announce the following DEC Statistics seminar: Thursday, November 28 12:30 Meeting room 3-e4-sr03, Bocconi University, Via Roentgen 1, 3rd floor Quentin Berthet (Google Research) Title: Optimal transport methods in statistics and machine learning: theory and applications Abstract: Optimal transport is one of the foundational problems of optimization, and a very important topic in analysis. It asks how one can transport mass with a given measure to have another measure, with minimal global transport cost. The associated Wasserstein distance is a useful statistical tool to compare distributions, taking into account geometric properties of the data. In this presentation, I will talk about two recent projects on this topic. In the first one, we propose a novel approach for unsupervised embedding alignment, and show applications to natural language processing. It is based on a new approach for Wasserstein loss minimization (joint work with E. Grave and A. Joulin). In the second one, we provide new methods and guarantees for estimation of distributions with smooth densities, in the Wasserstein distance. We show that these tools, inspired by techniques in nonparametric statistics, yield information-theoretic optimal results. We also develop ideas to handle our proposed estimators in a computationally efficient manner, and explore some of the associated computational trade-offs (joint work with J. Weed). Kind regards, Giacomo Zanella The DEC statistics seminars schedule is available at http://www.unibocconi.eu/statseminar Please note: if you are a guest and you do not have a Bocconi ID Card to access to the Bocconi Buildings, please communicate your participation by sending an email to elisa.picassi(a)unibocconi.it

STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO Venerdì 29 Novembre 2019, alle ore 12:00, presso il nuovo edificio del Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Robin RYDER (Université Paris Dauphine) A BAYESIAN NON-PARAMETRIC METHODOLOGY FOR INFERRING GRAMMAR COMPLEXITY Based on a set of strings from a language, we wish to infer the complexity of the underlying grammar. To this end, we develop a methodology to choose between two classes of formal grammars in the Chomsky hierarchy: simple regular grammars and more complex context-free grammars. To do so, we introduce a probabilistic context-free grammar model in the form of a Hierarchical Dirichlet Process over rules expressed in Greibach Normal Form. In comparison to other representations, this has the advantage of nesting the regular class within the context-free class. We consider model comparison both by exploiting this nesting, and with Bayes’ factors. The model is fit using a Sequential Monte Carlo method, implemented in the Birch probabilistic programming language. We apply this methodology to data collected from primates, for which the complexity of the grammar is a key question. (joint work with L. Murray, J. Rousseau and A. Thin) ------------------------------------------------ Tutti gli interessati sono invitati a partecipare.

Seminar Wadsworth @Bocconi
by Giacomo Zanella 18 Nov '19

18 Nov '19

We announce the following DEC Statistics seminar: Thursday, November 21 12:30 Meeting room 3-e4-sr03, Bocconi University, Via Roentgen 1, 3rd floor Jenny Wadsworth (Lancaster University) Title: Towards higher-dimensional spatial and spatio-temporal extremes Abstract: The past decade has seen a huge effort in modelling the extremes of spatial processes. Significant challenges include the development of models with an appropriate asymptotic justification for the tail; ensuring model assumptions are compatible with the data; and the fitting of these models to (at least reasonably) high-dimensional datasets. I will review basic ideas of modelling spatial extremes, and introduce a more scalable approach via conditioning on a single site being extreme, which can also be applied in the space-time context. Furthermore, the sometimes-undesirable nature of conditioning on an extreme event at a particular location can be circumvented by an importance sampling algorithm to change the conditioning event. As we move towards being able to model extremes at more locations, we must also learn to deal with the complex structures of larger datasets, such as spatial nonstationarity in the extremal dependence. Some approaches to simplify these structures via deformations tailored to extremal dependence will also be discussed. Kind regards, Giacomo Zanella The DEC statistics seminars schedule is available at http://www.unibocconi.eu/statseminar Please note: if you are a guest and you do not have a Bocconi ID Card to access to the Bocconi Buildings, please communicate your participation by sending an email to elisa.picassi(a)unibocconi.it

Seminar: okada@DISMEQ Department of Statistics and Quantitative Methods, University of Milano-Bicocca
by Fulvia Pennoni 18 Nov '19

18 Nov '19

----------------------------------------------------------------------------------- ** 21/11/2019 h.11.00 /Building U7 4th floor - Seminar Room 4026/ Department of Statistics and Quantitative-Methods, Via Bicocca degli Arcimboldi, 8 - 20126 Milano ----------------------------------------------------------------------------- MULTIDIMENSIONAL SCALING OF ASYMMETRIC RELATIONSHIPS Akinori Okada Professor Emeritus of the Rikkyo University, Tokyo okada(a)rikkyo.ac.jp Torgerson (1952) introduces his multidimensional scaling as the first practical method of representing proximity (similarity, dissimilarity) relationships among objects in a multidimensional space or a configuration. The method is called metric, which means that the observed proximities are assumed to be interval or ratio scaled values. Shepard (1962a, b) and Kruskal (1964a, b) introduced methods which are called nonmetric multidimensional scaling. Nonmetric multidimensional scaling assumes that the observed proximities are ordinal scaled values. This mean that only the information which of two proximities is larger (or smaller) than the other is utilized in the analysis. The nonmetric multidimensional scaling of Kruskal (1964a, b) has been used most frequently in practical applications of multidimensional scaling, and several multidimensional scaling methods based on the similar idea of Kruskal (1964a, b) have been introduced. The multidimensional scaling developed so far assumes that the proximity is symmetric. Several researchers focused their attention on the asymmetry in various sorts of proximity; similarity/dissimilarity judgment, same/different judgment, reaction time, social and psychological distance, and so on. It is meaningful to develop asymmetric multidimensional scaling which can represent asymmetric proximity relationships among objects in a configuration. Various kinds of procedures to analyze an asymmetric proximity matrix were invented. We concentrate on the multidimensional scaling which is based on the distance among points, each representing an object, in a multidimensional space (distance model). The asymmetric multidimensional scaling by Okada and Imaizumi (1987) represents asymmetric proximity relationships among objects by the interpoint distance in a multidimensional configuration. The distance between two points is symmetric. It is difficult to represent asymmetric relationships simply by the interpoint distance, because the distance itself is symmetric. The model of Okada and Imaizumi (1987), which is called Distance-radius model, represents an object by a point and a circle [two-dimensional model] (sphere [three-dimensional] or hypersphere [larger than three-dimensional]) centered at the point in a multidimensional space. Several models were derived from the model. Multidimensional scaling mentioned above, regardless of metric or nonmetric and of being able to represent asymmetry or not, analyzes one proximity matrix (object x object) or one-mode two-way proximities (Carroll and Arabie, 1980). To analyze a set of proximity matrices each comes from a source (object x object x source) or two-mode three-way proximities, INDSCAL was developed by Carroll and Chang (1970). INDSCAL can represent relationships among objects and how each source (individual) has different relationships among objects each other. While INDSCAL can represents differences among sources, it cannot represent the asymmetry in relationships among objects of each source. The model of Okada and Imaizumi (1997) is an extension of the Distance-radius model which can analyze a set of asymmetric proximity matrices or two-mode three-way asymmetric proximities. The asymmetric multidimensional scaling of Okada and Imaizumi (1997) can represents asymmetric relationships among objects, and how each source has different symmetric and asymmetric relationships among objects each other as well. Several models, which are less restricted or more restricted, have been derived from Okada and Imaizumi (1997). To analyze one-mode two-way asymmetric proximities, there is another asymmetric multidimensional scaling by Okada (2011) and Okada and Tsurumi (2012) which is based on the singular value decomposition. The asymmetric multidimensional scaling has been utilized to analyze mainly the data from marketing research or brand switching. Several models and procedures have been derived by extending the model of Okada (2011) which can, for example, evaluate newly introduced brands, diagnose brands, tell how to increase the dominance of a brand in the brand switching... Another sort of procedure to analyze one-mode two-way asymmetric proximities is asymmetric cluster analysis, which can represent asymmetric proximity relationships among objects by forming clusters (Okada & Iwamoto, 1966; Okada & Yokoyama, 2015). It is important and meaningful to develop not only multidimensional scaling but also cluster analysis as well so that we can use two different kinds of methods to analyze the same proximity data (Arabie & Hubert, 1994). There are quite a few number of applications of asymmetric multidimensional scaling and cluster analysis. While these applications are not mentioned here because of the space limitation, some of them will be mentioned in the talk. The present abstract deals only with researches of the author and his colleagues. Bove and Okada (2018) gives a review which covers a wide range of asymmetric multidimensional scaling and asymmetric cluster analysis in detail. Some books mention the analysis of asymmetric relationships. Borg and Groenen (2005) has a chapter of asymmetric multidimensional scaling. Coxon and Coxon (2001) refers to asymmetric multidimensional scaling. **/References/// Arabie, P. & Hubert, L. (1994). Cluster analysis in marketing research. In Bagozzi, R. F.

by Francesca Romana Nardi 15 Nov '19

15 Nov '19

Ecco il reminder per Venerdi` 22 Novembre. Vi aspettiamo numerosi Gianmarco Bet e Francesca R. Nardi From: Francesca Romana Nardi [mailto:francescaromana.nardi@unifi.it] Sent: Thursday, November 7, 2019 10:33 AM To: 'random(a)fields.dm.unipi.it' <random(a)fields.dm.unipi.it> Subject: AN``AUTUMN'' DAY IN PROBABILITY AND STATISTICAL PHYSICS - 22 November 2019 (Jansen e Avena) Carissimi, Vi annunciamo che prossimamente si terrà la nona giornata di seminari: AN ``AUTUMN'' DAY IN PROBABILITY AND STATISTICAL PHYSICS University of Florence Friday 22 November 2019 Lecturers: Sabine Jansen (Munich) and Luca Avena (Leiden) Location: Aula Tricerri Viale Morgagni 67, Firenze Informazioni su come arrivare alla pagina: <https://www.dimai.unifi.it/vp-285-come-arrivare-how-to-get.html> https://www.dimai.unifi.it/vp-285-come-arrivare-how-to-get.html Note pratiche: Stiamo prenotando un catering con cibi vegerariani e non, percio` abbiamo bisogno del numero di persone che vogliono mangiare insieme. A coloro che fossero interessati (per una migliore organizzazione) chiediamo di mandare un email a <mailto:francescaromana.nardi@unifi.it> francescaromana.nardi(a)unifi.it; <mailto:gianmarco.bet@unifi.it> gianmarco.bet(a)unifi.it; <mailto:angela.caporicci@unifi.it> angela.caporicci(a)unifi.it con l'intenzione di partecipare al seminario, al coffe break e al pranzo. PROGRAMMA Prof. Sabine Jansen (LMU Munich) Title: Large deviations and metastability for the Widom-Rowlinson model Abstract: The Widom-Rowlinson model is one of the few models in statistial mechanics for which a phase transition is rigorously proven. It is also popular in stochastic geometry and spatial statistics where it is called area interaction model and belongs to the broader class of quermass interaction models. After reviewing some relevant background about Gibbs measures for continuum interacting particle systems, I will discuss large deviations for the Widom-Rowlinson model in a joint high-density / low-temperature limit. I will also discuss metastability for a spatial birth and death process, a.k.a. continuum Glauber or grand-canonical Monte-Carlo, for which the Gibbs measure is reversible. Based on joint work with Frank den Hollander, Roman Kotecký and Elena Pulvirenti. Prof. Luca Avena (University of Leiden) Title: Explorations of networks through random spanning forests: theory and applications Abstract: David Wilson in the 1990s described a simple and efficient algorithm based on loop-erased random walks to sample uniform spanning trees and, more generally, weighted rooted trees or forests spanning a given graph. The goal of this lecture is to describe the resulting probability measure when Wilson's algorithm is used to sample rooted spanning forests. This forest-measure has a rich, flexible and explicit mathematical structure which makes it a powerful tool to design different algorithms to explore a given network. In the first part of the lecture, I will focus on fundamental aspects of this measure and how it relates to other objects of interest in statistical physics such as the well known Random-cluster model. I will in particular describe the main properties of related observables (e.g. set of roots, induced partition) which turn out to be determinantal processes with simple kernels and then discuss some progress in understanding related scaling limits. The second part of the lecture will be devoted to applications. In particular, depending on time, I plan to discuss four different algorithms aiming at: (1) sampling well-distributed points in a graph, (2) coarse-graning a given network, (3) processing signals on graphs (a novel gaph wavelet transform), (4) estimating the spectrum of the graph Laplacian. The core of this lecture is based on different joint collaborations with the following colleagues and students: Castell, Gaudillere, Melot, Milanesi (Marselle), Quattropani (Rome), Driessen, Koperberg, Magrini (Leiden) , Amblard, Barthelme, Tremblay (Grenoble). Program: 11.00-11.45 Introductory lecture: Jansen 11.45-12.00 Break 12.00-12.45 Seminar: Jansen 13.00-14.30 Lunch 14.30-15.15 Introductory lecture: Avena 15.15-15.30 Break 15.30-16.30 Seminar: Avena Organizers: G.

Seminario Luca Avena a Pisa
by Dario Trevisan 13 Nov '19

13 Nov '19

Dear all, this is to announce the following research talk by Luca Avena, to be held in Pisa. PLACE: Aula Riunioni, Dipartimento di Matematica, Università di Pisa (first floor). DATE & TIME: Wednesday, Nov 20, 2019, 2 PM SPEAKER: Luca Avena (Univ. Leiden) TITLE: Multiscale analysis of network data sets via random walk kernels. ABSTRACT: I will present a random walk approach to analyse data sets that are encoded into a network structure (a weighted graph). Random walks are natural objects to explore a given network and have been used as building blocks to design different type of algorithms such as the celebrated PageRank. The core of this lecture is on three new general algorithms aiming at: 1) sampling well-distributed points in a graph, 2) coarse graining a given network at different scales, 3) processing signals on graphs through a novel wavelets transform. As I will discuss, these algorithms can be good or not depending on the specific data set problem to be analyzed. The main emphasis will be given on the underlying mathematical structures which are of fundamental interest per se within probability theory and statistical phyisics. Partially based on joint work with Castell, Gaudilliere and Melot Best regards, Dario -- Dario Trevisan, Università degli Studi di Pisa, Dipartimento di Matematica, Largo Bruno Pontecorvo 5, 56127 - Pisa (PI) Italy telephone: (+39) 050 2213832 mobile: (+39) 331 2899761 Skype: dario-trevisan e-mail: dario.trevisan AT unipi.it webpage: http://people.dm.unipi.it/trevisan/
