Feature Construction for Time Series and non-Time Series Datasets in Remote Sensing

Transmissão através de Videoconferência

Por João Batista.

Deforestation has serious implications on biodiversity, on rural communities that are dependent on forests for food and income, and on greenhouse gas emissions that are driving the global climate. One way to control deforestation is through the use of mechanisms that promote sustainable forestry and support economic development, like REDD+ of the United Nations. However, to be effective, these mechanisms require careful forest monitoring.

Having this into consideration, this work attempts to improve the quality of the results produced by the Machine Learning methods used by Remote Sensing experts for forest monitorization. To do so, this work promotes the use of automatic Feature Construction methods for multiclass classification in both Time Series and non-Time Series datasets that were extracted from satellite imagery. In particular, this work uses two methods based on Genetic Programming (Standard GP and M3GP) to perform Feature Construction and state-of-the-art methods (e.g., XGBoost and ROCKET) to classify the datasets.

Um programa de aceleração de ideias e negócios, promovido pela redeSaúde, com candidaturas até 30 de setembro de 2021.

The objective of this course is to introduce participants to the details of communicating science to non-specialized audiences, including, but not exclusive to, public and private stakeholders, students and teachers, and media professionals.

This course aims to evidence the importance of natural history collections for the study of biodiversity, to show new tools and approaches to extract and disseminate biodiversity data from natural history collections and to increase awareness of young researchers for the scientific and cultural value of Natural History Museums.

The course aims at providing an introduction to stable isotopes ratios as tools to understand global, ecosystem and community level bio/geo cycles; light isotopes: H, N, C, O and S isotopes, geo cycles and ecological significance; sampling and analytical methodologies in stable isotope analysis.

EvoS aims at turning evolutionary theory into a common language to areas that pertain to the natural world, including human affairs.

The course SoilEco aims at introducing attendants to an updated state of the art of diversity of the soil biota and the functional roles played by soil organisms in key ecological processes.

In this course, we promote a multidisciplinary approach presenting the most recent findings on the topic and challenging the traditional way of considering symbiotic associations as exceptions and not as the rule.

The goal of this course is to provide to the participants with current and practical knowledge on urban ecology, including ecological and social aspects.

This course aims to explore ways of communicating science to non-specialized audiences, such as policy makers, industry, general public (including students and teachers), through their engagement and participation in citizen science activities.

This course introduces the field of island biogeography, a discipline that has long influenced other research areas such as macroecology, community ecology, evolution and conservation biology.
