Discuss the differences between dimensionality reduction based on aggregation

1. Obtain one of the data sets available at the UCI Machine Learning Repository and apply as many of the different visualization techniques described in the chapter as possible. The bibliographic notes and book Web site provide pointers to visualization software.
2. Identify at least two advantages and two disadvantages of using color to visually represent information.

What are the arrangement issues that arise with respect to three-dimensional plots?
Discuss the advantages and disadvantages of using sampling to reduce the number of data objects that need to be displayed. Would simple random sampling (without replacement) be a good approach to sampling? Why or why not?
Describe how you would create visualizations to display information that de-scribes the following types of systems.
a) Computer networks. Be sure to include both the static aspects of the network, such as connectivity, and the dynamic aspects, such as traffic.

b) The distribution of specific plant and animal species around the world fora specific moment in time.

c) The use of computer resources, such as processor time, main memory, and disk, for a set of benchmark database programs.

d) The change in occupation of workers in a particular country over the last thirty years. Assume that you have yearly information about each person that also includes gender and level of education.

Be sure to address the following issues:

· Representation. How will you map objects, attributes, and relation-ships to visual elements?

· Arrangement. Are there any special considerations that need to be taken into account with respect to how visual elements are displayed? Specific examples might be the choice of viewpoint, the use of transparency, or the separation of certain groups of objects.

· Selection. How will you handle a large number of attributes and data objects

1. Describe one advantage and one disadvantage of a stem and leaf plot with respect to a standard histogram.
2. How might you address the problem that a histogram depends on the number and location of the bins?
3. Describe how a box plot can give information about whether the value of an attribute is symmetrically distributed. What can you say about the symmetry of the distributions of the attributes shown in Figure 3.11?
4. Compare sepal length, sepal width, petal length, and petal width, using Figure3.12.
5. Comment on the use of a box plot to explore a data set with four attributes: age, weight, height, and income.
6. Give a possible explanation as to why most of the values of petal length and width fall in the buckets along the diagonal in Figure 3.9.
7. Use Figures 3.14 and 3.15 to identify a characteristic shared by the petal width and petal length attributes.
8. Simple line plots, such as that displayed in Figure 2.12 on page 56, which shows two time series, can be used to effectively display high-dimensional data. For example, in Figure 2.12 it is easy to tell that the frequencies of the two time series are different. What characteristic of time series allows the effective visualization of high-dimensional data?
9. Describe the types of situations that produce sparse or dense data cubes. Illustrate with examples other than those used in the book.
10. How might you extend the notion of multidimensional data analysis so that the target variable is a qualitative variable? In other words, what sorts of summary statistics or data visualizations would be of interest?
11. Construct a data cube from Table 3.14. Is this a dense or sparse data cube? If it is sparse, identify the cells that are empty.
12. Discuss the differences between dimensionality reduction based on aggregation and dimensionality reduction based on techniques such as PCA and SVD.

ARTH 3011 Research Essay Outline

ARTH 1130 Research Essay Outline (one page, double-spaced, 12 pt. font) (10%)

The purpose of this exercise is to give you a chance to plan a coherent research project. The project is to be comparative (involving two works of art/artifacts/monuments from the same period). We want to see that you’ve chosen material to work with in your research essay that is both interesting to you and relevant to the class. In this proposal you will show that you have carefully selected artworks and texts to begin to answer a guiding research question. While your answer to this research question will come together in the course of reading, thinking and writing, for the proposal we would like to see you attempt an answer or a thesis statement.

Write in paragraphs where applicable and label the sections of the proposal following this breakdown:

1) Name two objects from one period(artworks/artifacts/monuments) that you will compare/contrastin your essay. Use the periods in the Kleiner texts as a guide or, if you are choosing objects from a non-Euro-American tradition make sure your two objects were produced within 100years of one another. You are free to choose something not included in the textbook, but make sure you have access to information about the objects you choose. You should include images of your objects and their titles where applicable, the names of their makers if they are known, the date of their production, and their current place of display. (2%) 2) A research question and thesis statement (or answer to your question) that is aimed at clarifying a relationship of some kind between the objects. Here are the broad outlines of some possible research questions: On what grounds can we compare/contrast the quality of the objects (why is one better or worse than the other, and by what standard)? How do the materials used in these objects, or the technologies involved in their making determine their form? How have the makers of these objects been steered in their creative process by the (social, political, economic) forces of history? How did these objects steer the course of the histories of which they are a part? On what grounds are these objects included by art historians in particular national traditions or cultures? How do the objects contribute to a group or personal identity? How do the objects deliver a social or political commentary? To what end do the objects enlist techniques of representation and/or abstraction? How do the objects interact with or function in their sites of display? After posing your question, venture an answer to it in the form of a thesis statement. This should be a paragraph long in total. State your question and tell us how you arrived at it. (3%)3) A brief description of intrinsic and extrinsic aspects of the objects and their histories that you will explore in your essay. Intrinsic factors are material or formal features of the objects. Extrinsic factors are aspects of the social, political, historical, technological context surrounding the objects. This should be one paragraph long. (3%)4) A bibliography of at least 5 sources (not including Kleiner)you will consult in your research. Include all the information you can find on your sources: author, title, date and place of publication, etc. Consult a style guide for this bibliography (MLA or Chicago are preferred). A maximum of 2 of your sources may be non-academic (i.e. magazine articles or reviews; exhibition or curatorial statements; statements from artists or curators in recorded interviews or presentations). The remaining 3 sources should be academic (i.e. articles from peer-reviewed journals; books; conference proceedings or recorded academic lectures). (2%)
