Crowd Computing: From Human Computation to Collective Intelligence

Summary:
Crowd computing - systems where crowds (of people) and clouds (of computers) work together to make better decisions than any could make individually - exploded onto the scene in the last decade or so with such startling success stories as Wikipedia, Linux, Mechanical Turk, Google search, Galaxyzoo, Sermo, Slashdot, Seeclickfix, fold.it and hundreds of others, with profound and still emerging impacts on everything from science and education to entertainment, business, and government. This phenomenon is many-sided, ranging from human computation (where humans act as subroutines, performing simple micro-tasks to support some larger computation) to collective intelligence (where computers support communities in making decisions about our species’ most complex and pressing problems). This tutorial will help participants:

  • understand what makes crowd computing so potentially powerful
  • be familiar with the key types of crowd computing technology, including their strengths and weaknesses
  • identify promising directions for future research in this area.

ACBG is a Full Professor at Departamento de Informática Aplicada, UNIRIO. She was a professor at UFF from 1994-2017. She did her master and PhD studies at Stanford University. She was a visiting scholar at Stanford in 2002 and at MIT in 2013. She advised 8 PhDs and 30 Master’s students. She founded and coordinated until 2017 the ADDlabs, a research lab in artificial intelligence. MK is a Principal Research Scientist at the MIT Center for Collective Intelligence, as well as an Visiting Researcher at the University of Zurich. His research focuses on understanding how computer technology can help groups, especially large ones, make better decisions about complex problems. He has made contributions in the areas of computer-supported conflict management for collaborative design, design rationale capture, business process re-design, exception handling in workflow and multi-agent systems, service discovery, negotiation algorithms, ‘emergent’ dysfunctions in distributed systems and, more recently, ‘collective intelligence’ systems to help people collaboratively solve complex problems like global warming.

A Hybrid Method for Forecasting in Smart Grids Scope

Summary:
Smart Grids emerge as the next technological breakthrough to be achieved for systems of power generation, transmission and distribution. In a Smart Grid, the boundaries between generation and consumption/distribution are blurred. Therefore loading forecasting and generation forecasting processes are signifcantly different from the ones for stablished/legacy power systems. This tutorial turns to the study of forecasting methods in the scope of Smart Grids and how these methods are applicable in their intelligent behavior. It is imperative to have a consistent framework for short-term prediction meeting operating characteristics of Smart Grids. ARMA-like traditional models of time series prediction has been applied in Electric Power Systems, such as SARIMA and SARFIMA. To improve the accuracy of these methods, hybrid methods will be developed integrating fuzzy logic to SARIMA and SARFIMA models. The proposed models are based on the technique of Fuzzy Time Series (FTS). The proposed models meet the need for methods that rely less on strong stationarity assumptions and are parsimonious in its parameters, even though it deals with stochastic long memory processes. In this tutorial, proposed algorithmic solutions will be shown and analyzed, mainly in the form of hybrid SARFIMA methods and Fuzzy Time Series (SARFIMAFTS). This framework has been applied successfuly to many important problems instances from large national power load curves to minigrids. After the presentation of this framework and its results, a round table will be carried out with a number of expoents in this research area.

I have a bachelor in engineering by the Federal University of Ouro Preto, my master of science in a double-diploma scheme (Erasmus programme) by the University of L’Aquila/Gdansk University of Technology, in mathematical engineering/technical physics, and my PhD by the University of L’Aquila in Information Engineering (ICT). I have been working on computational intelligence since my bachelor, I have started a master by UFRJ in CI, and I have started to work on biomathematics at University of L’Aquila. Since then, I have attended to several events in biomathematics, mainly systems biology, and computational intelligence (my main interest is artificial neural networks). My main interest is teaching/working with biologists and medical doctors, as I did in my PhD, and intend to keep doing so.

Search-based Software Engineering (SBSE)

Summary:
Este tutorial terá duas fases. Sendo a primeira para introduzir a teoria e algumas aplicações (50 minutos), e a segunda para as demonstrações (40 minutos). Sendo assim, inicialmente serão apresentadas as atividades da Engenharia de Software que podem ser modeladas como problemas de busca e otimização. Posteriormente, as complexidades de alguns desses problemas serão mostradas e, por fim na fase 1, alguns modelos e métodos aplicados em alguns trabalhos serão discutidos. Já na fase 2, pretende-se, inicialmente, apresentar videos de execuções e resultados de meta-heurísticas para diferentes problemas abordados na SBSE. Por fim, será feita uma demonstração, ao vivo, da execução de um método em um benchmark da área de SBSE.

Programação Genética: Fundamentos e Aplicações

Summary:
A Programação Genética (PG) é um método de computação evolucionária largamente utilizado para problemas interessantes do mundo-real. Basicamente, PG evolui uma população de programas (usualmente representados como árvores complexas), e cada elemento da população representa uma possível solução para um problema de otimização. Há muitas classes de problemas onde PG pode ser aplicada com sucesso, tais como mineração de dados, reconhecimento de padrões, jogos e estratégias de aprendizado. Neste tutorial serão apresentados os fundamentos de PG de uma forma acessível, tal que a audiência inclui tanto alunos de graduação como de pós-graduação. Ao longo do tutorial, diversas aplicações reais serão apresentadas de modo a ilustrar a aplicabilidade de PG.
