atualizacao: seminario internacional na USP-SP e UFMG

[Renato Assunção <assuncao@est.ufmg.br>]

Caros colegas,

quero anunciar o horario e local na UFMG do minicurso em visualizacao
de dados do professor Juergen Symanzik
nos dias 30/11 (segunda), 01/12 e 02/12. Sera' uma sequencia de
tecnicas modernas de analise de dados
baseada em visualizacao de dados. Poucas formaulas e muitas imagens.
Um show de cores, movimento
e informacao. Nao percam.

Aqueles interessados em ir ao jogo do Cruzeiro x Curitiba comigo e com
o professor Juergen no domingo,
mandem-me e-mail.

Um abraco a todos,
Renato Assuncao
PS: o professor Juergen esta' disponivel para conversar com alunos
interessados em fazer pos-graduacao
nos EUA com bolsa dos proprios deptos nos EUA.

Session 1: SEGUNDA_FEIRA, 30/11, de 11:00 as 12:00, ICEx,
Sala de seminários do DCC - 2077

Title: Interactive and Dynamic Statistical Graphics - An Overview

Abstract:

Interactive and dynamic statistical graphics enable data analysts
in all fields to carry out visual investigations leading to insights
into relationships in complex data. Interactive and dynamic statistical
graphics involve methods for viewing data in the form of point clouds
or modeled surfaces. Higher-dimensional data can be projected
into one-, two- or three-dimensional planes in a set of multiple
views or as a continuous sequence of views which constitutes motion
through the higher-dimensional space containing the data.
In this session, we will introduce the main techniques for interactive
and dynamic statistical graphics (e.g., linking, brushing,
scatterplots and scatterplot matrices, parallel coordinate plots,
and grand tour) and commonly used software that is freely available
on the Web (e.g., GGobi/Rggobi, CrystalVision, and Mondrian/iplots).
Sessions 2 and 3 will extensively use methods and ideas introduced
in this session.


Session 2: TERCA_FEIRA, 01/12, de 10:30 as 11:30, ICEx,
Sala de seminários do DCC - 2077

Title: Linked Micromap Plots - In Print and on the Web

Abstract:

Linked micromap (LM) plots provide a new statistical paradigm
for the viewing of geographically referenced statistical
summaries in the corresponding spatial context.
The main idea behind LM plots is to focus the viewer's
attention on the statistical information presented in a
graphical display. Multiple small maps are used to provide
the appropriate geographic reference for the statistical data.
In this session, we will present our efforts in visualizing the
spread of the West Nile Virus via Web-based LM plots.
Examples for the use of static LM plots include the
distribution of birth defects in Utah and the entire United States,
as well as the distribution of air pollutants across the United States.


Session 3: QUARTA_FEIRA, 02/12, de 10:30 as 11:30, ICEx,

Title: Interactive and Dynamic Statistical Graphics - Special Applications

Abstract:

In this session, we will look at two special applications for interactive
and dynamic statistcal graphics. First, we introduce the circular dataimage,
a new type of graphic for the display of circular-spatial data. Circular
dataimages encode direction in a spatial display by using colors from a color
wheel constructed by connecting three or more two-color gradients with color
continuity at the connections and, therefore, avoiding image discontinuity.
As an example, we look at ocean wind direction data. Next, we describe
how high-interaction visual data mining has been successfully
used to cluster archaeological data in a spatial framework.
