We will address both complex and extreme measurements from these systems. There is a necessity to classify appropriate learning mechanisms and define transfer functions and statistics. A natural question may arise: how to address extreme parts of data? How to define boundaries of the datasets and what can be the effects on statistical properties of estimated structures (e.g. uniqueness of copulas? Can we provide efficient estimators of extremes? For closed physical systems, all can be well integrated into both natural and technical sciences, which gives us an optimal instrument for the decomposition of data into stochastic, deterministic, and chaotic part. In particular, we will introduce SPOCU transfer function and provide some of its unique properties for processing of complex data, statistical learning will be discussed, and tuning of parameters of SPOCU-based neural networks will be explained. During the talk, I will acknowledge the contributions of the Portuguese Extreme group and outline some relations to t-Hill-based estimators. The t-Hill approach will be introduced from a robustness perspective, mentioning and interconnecting with articles, among others. Attractive applications to biological systems, such as mass balance in the ecosystem of glaciers in Patagonia, or methane emissions from wetlands will be addressed.</p></div> <div class='nota_sessao' style='border: thin solid #777;font-size:80%;padding:0.5em;margin-top:1em'><p>Joint seminar <a href="https://cemat.tecnico.ulisboa.pt">CEMAT</a> and <a href="https://ceaul.org/o-centro/">CEAUL</a></p></div> </article> </div> </div> </main> <footer style='clear:both;background-color: white;text-align:center'> <center style="text-align:center"> <a href="https://ceaul.org/"> <picture> <img src='/img/CEAUL.png' alt='CEAUL' height="40" width="129" title='Centro de Estat铆stica e Aplica莽玫es Universidade de Lisboa' style="height:30px;width:auto"/> </picture> </a> <a href="https://cemat.tecnico.ulisboa.pt/"> <picture> <source srcset="/img/logo_cemat-18.svg" type="image/svg+xml" /> <img src='/img/cemat_h40.png' alt='CEMAT' height="40" width="110" title='Center for Computational and Stochastic Mathematics' style="height:30px;width:auto"/> </picture> </a> <a href='https://tecnico.ulisboa.pt'> <picture> <source srcset="/img/Tecnico_logo.svg" type="image/svg+xml" /> <img src='/img/IST_Logo_2012_h30.png' height='30' width='77' alt="T茅cnico" title="Instituto Superior T茅cnico" style="height:30px;width:auto" /> </picture> </a> <a href='https://www.fct.pt'> <picture> <source srcset="/img/FCT_2022.svg" type="image/svg+xml" /> <img src='/img/FCT_2022_h40_w126.png' height='40' width='126' alt="FCT" title="Funda莽茫o para a Ci锚ncia e a Tecnologia" style="height:30px;width:auto" /> </picture> </a> </center> </footer> </div> </body> </html>
