LGP-30 no MIT, teve que dedicar uma sala espec\u00edfica para deixar o monstro barulhento trabalhando. Talvez poucas pessoas saibam, mas Lorenz tinha colaboradoras como as pesquisadoras Margaret Hamilton (que depois foi uma pe\u00e7a-chave na miss\u00e3o de Apolo 11) e Ellen Fetter, que o ajudaram a domar aquele computador na realiza\u00e7\u00e3o de seus c\u00e1lculos. O artigo do Lorenz (com colabora\u00e7\u00e3o de Fetter) publicado em 1963 no Journal of Atmospheric Science com o t\u00edtulo &#8220;Deterministic non-periodic flow&#8221; criou um caos no mundo da matem\u00e1tica, tal como o bater de asas de uma borboleta. Entretanto, aquela borboleta matem\u00e1tica j\u00e1 tinha, de certa forma, come\u00e7ado a nascer, antes, talvez no formato de lavra ainda, presente nos trabalhos de Richardson, que podem ser conferidos no livro &#8220;Weather prediction with numerical process&#8221;.<\/p><p>\u00a0<\/p><p>O sucesso do efeito borboleta foi tamanho que sua fama alcan\u00e7ou at\u00e9 as salas de cinema. Seus efeitos foram sentidos no mundo dos n\u00fameros e se entrela\u00e7ou nos trabalhos de Joan Birman e Robert F. Williams, ganhando complexidade topol\u00f3gica. Hoje, as asas da borboleta dan\u00e7am ao longo de n\u00f3s, tecendo afinidades com a \u00e1rea de grupo modular em teoria de n\u00fameros (mostrado por E. Ghys). Foram os estudos desse grupo modular que geraram dan\u00e7as algo-ritmicas na pra\u00e7a XV de Novembro, em S\u00e3o Carlos, durante o festival Pint of Science, em 2024.<\/p><p><strong>\u00a0<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-d816790 e-con-full e-flex jltma-glass-effect-no elementor-invisible e-con e-child\" data-id=\"d816790\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;animation&quot;:&quot;fadeIn&quot;}\">\n\t\t<div class=\"elementor-element elementor-element-74afc1c e-con-full e-flex jltma-glass-effect-no e-con e-child\" data-id=\"74afc1c\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-104b7f8 jltma-glass-effect-no elementor-widget elementor-widget-image\" data-id=\"104b7f8\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"300\" height=\"300\" src=\"https:\/\/sbm.org.br\/coloquio-sudeste-5\/wp-content\/uploads\/sites\/42\/2026\/08\/Flavio-Bambirra-Goncalves.png\" class=\"attachment-full size-full wp-image-373\" alt=\"\" srcset=\"https:\/\/sbm.org.br\/coloquio-sudeste-5\/wp-content\/uploads\/sites\/42\/2026\/08\/Flavio-Bambirra-Goncalves.png 300w, https:\/\/sbm.org.br\/coloquio-sudeste-5\/wp-content\/uploads\/sites\/42\/2026\/08\/Flavio-Bambirra-Goncalves-150x150.png 150w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-79df9d0 e-con-full e-flex jltma-glass-effect-no e-con e-child\" data-id=\"79df9d0\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-aa7048a jltma-glass-effect-no elementor-widget elementor-widget-heading\" data-id=\"aa7048a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Scalable Bernoulli Factory MCMC for Intractable Marginalised Posteriors<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a521067 jltma-glass-effect-no elementor-widget elementor-widget-heading\" data-id=\"a521067\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Fl\u00e1vio Bambirra Gon\u00e7alves<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c97e79a jltma-glass-effect-no elementor-widget elementor-widget-heading\" data-id=\"c97e79a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Universidade Federal de Minas Gerais<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-57db2a9 para jltma-glass-effect-no elementor-widget elementor-widget-text-editor\" data-id=\"57db2a9\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p><strong>Resumo: <\/strong>Bernoulli factory MCMC} algorithms implement accept-reject Markov chains without explicit computation of acceptance probabilities, and are used to target posterior distributions associated with intractable likelihood models. Intractable likelihoods naturally arise in continuous-time models and mixture distributions, or from the marginalisation of a tractable augmented model. Bernoulli factory MCMC algorithms often mix better than alternatives that target a tractable augmented posterior. However, we show that their computational performance typically deteriorates exponentially with data size, as happens in naively implemented pseudo-marginal algorithms. To address this, we propose a simple divide-and-conquer Bernoulli factory MCMC algorithm and prove that it has polynomial complexity for factorising models, with the exact degree depending on the existence of efficient unbiased estimators of the intractable likelihood ratio. We demonstrate the effectiveness of our approach with applications to Bayesian inference in two intractable likelihood models, and observe respective polynomial cost of degree 1.2 and 1 in the data size.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-a375317 e-con-full e-flex jltma-glass-effect-no elementor-invisible e-con

Extracting precise metrics such as plant height, canopy density, and leaf cover from high-resolution aerial imagery requires robust statistical segmentation to separate plant structures from the background. We model these images using a Gaussian mixture driven by a hidden Markov Random Field (MRF). A central statistical challenge in this formulation is the joint estimation of the interacting neighborhood structure of the hidden MRF and the number of Gaussian mixture components. To address this, we propose a Bayesian Reversible Jump Markov Chain Monte Carlo (RJMCMC) algorithm that explores subsets of a maximal interaction neighborhood. Model selection is performed using a marginal pseudoposterior distribution, effectively mitigating the computational burden of intractable normalization constants. This framework enables precise digital trait extraction, providing scalable insights into crop performance and supporting variety selection for agricultural management.<\/p><p>\u00a0<\/p><p>Joint work with Victor Freguglia, Guilherme Francio Niederauer and Mateus Figueiredo<strong><br \/><\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-43658b0 e-con-full e-flex jltma-glass-effect-no elementor-invisible e-con e-child\" data-id=\"43658b0\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;animation&quot;:&quot;fadeIn&quot;}\">\n\t\t<div class=\"elementor-element elementor-element-ed0b362 e-con-full e-flex jltma-glass-effect-no e-con e-child\" data-id=\"ed0b362\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-15028c1 jltma-glass-effect-no elementor-widget elementor-widget-image\" data-id=\"15028c1\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"425\" height=\"425\" src=\"https:\/\/sbm.org.br\/coloquio-sudeste-5\/wp-content\/uploads\/sites\/42\/2026\/08\/Pablo-Carrasco-e1789507132137.jpg\" class=\"attachment-full size-full wp-image-381\" alt=\"\" srcset=\"https:\/\/sbm.org.br\/coloquio-sudeste-5\/wp-content\/uploads\/sites\/42\/2026\/08\/Pablo-Carrasco-e1789507132137.jpg 425w, https:\/\/sbm.org.br\/coloquio-sudeste-5\/wp-content\/uploads\/sites\/42\/2026\/08\/Pablo-Carrasco-e1789507132137-300x300.jpg 300w, https:\/\/sbm.org.br\/coloquio-sudeste-5\/wp-content\/uploads\/sites\/42\/2026\/08\/Pablo-Carrasco-e1789507132137-150x150.jpg 150w\" sizes=\"(max-width: 425px) 100vw, 425px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-509b45d e-con-full e-flex jltma-glass-effect-no e-con e-child\" data-id=\"509b45d\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-50b27ff jltma-glass-effect-no elementor-widget elementor-widget-heading\" data-id=\"50b27ff\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">The Moduli Space of Metric Structures<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f1a3f44 jltma-glass-effect-no elementor-widget elementor-widget-heading\" data-id=\"f1a3f44\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Pablo Carrasco<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a9b34f3 jltma-glass-effect-no elementor-widget elementor-widget-heading\" data-id=\"a9b34f3\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Universidade Federal de Minas Gerais<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c73937b para jltma-glass-effect-no elementor-widget elementor-widget-text-editor\" data-id=\"c73937b\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p><strong>Resumo: <span style=\"font-weight: 400\">In this talk I will introduce a metric geometry on the space of (weakly hyperbolic) metric structures on a closed surface of genus at least two.

In this talk, we focus on modeling the dependence structure among the multiple factors influencing gender parity in mathematics using Bayesian networks. In particular, we develop a robust quantile-based formulation that allows these relationships to be explored beyond traditional mean-based approaches, providing greater flexibility in the presence of outliers, heteroscedasticity, and departures from standard distributional assumptions. We also introduce a quantile-based criterion for robust network structure learning. The proposed framework is used to investigate gender parity in undergraduate mathematics and STEM education in Brazil, providing a multivariate perspective on how educational, economic, and social factors interact and contribute to regional differences in female participation.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Palestras Plenarias Deu caos na matem\u00e1tica?
