Who Cares About the Arts?

Predicting Formal Arts Participation from Survey Data

Angela Han

ECE 539

December 2005


Project objective l.jpg
Project Objective

  • Apply pattern classifier neural network to arts marketing survey data

  • Use neural network as a predictive model to identify potential arts patrons


Slide3 l.jpg
Data

  • Americans and the Arts (1992)

    • Telephone survey administered February 1992

    • 1500 adults across the United States

    • Asked ~160 questions about participation, opinions, socialization, and support of the arts

  • Data stored on The Cultural Policy and the Arts National Data Archive www.cpanda.org


Inputs l.jpg
Inputs

  • 6 categories of survey questions

    • Demographics

    • Opinions on art, leisure, and artists

    • Participation in arts and leisure activities

    • Barriers to participation

    • Arts on TV

    • Arts socialization

    • Support for arts and culture

  • Not all questions were used as inputs – only measurable ones (33 out of ~160 questions)


Inputs5 l.jpg
Inputs

  • Sample questions used for inputs:

    • What is the last grade or level of school you completed?

    • Approximately how often did you go to the movies in the past 12 months?

    • How often would you estimate you buy compact discs, tapes, records, or recordings of classical music – do you buy classical music or recordings frequently, every once in a while, only occasionally, or almost never?

    • Over the past 12 months, have you personally or your immediate family contributed any money to an arts organization or an arts fund, or not?


Outputs l.jpg
Outputs

  • 6 survey questions were modified to become yes/no outputs for neural network:

    Not counting any performances given by your children in

    connection with school or classes, approximately how

    many times in the past 12 months did you go to…

    • live theater performances

    • live classical music performances

    • live performances of opera or musical theater

    • live performances of dance (ballet, modern, folk/ethnic, or jazz)

    • art museums or art galleries

    • science, or natural history museums or a history museum


The model l.jpg
The Model

  • A back propagation multilayer perceptron model was developed using the bp.m Matlab program from the course

  • The following parameters were used:

    • L=2, hidden layer=10 neurons

    • alpha=0.01, mu=0.8

    • epoch size=100, max epochs=2000.


The results l.jpg
The Results

  • bp.m was run for each of the six questions – data set was the same except for the outputs. Crate and error were calculated.

  • These are not the most ideal results!


Discussion l.jpg
Discussion

  • The data is possibly flawed

    • Example 1: respondents were asked if they purchased classical music recordings “frequently”, “every once in a while”, “only occasionally”, “almost never”, and “never.”

      • All of these choices are subjective, similar purchasing habits could be placed in different categories.

    • Example 2: respondent could respond positively to attending classical music concerts in the past 12 months when he/she had actually been attending jazz concerts, or could respond to attending an art museum when it was really a natural history museum.


Discussion10 l.jpg
Discussion

  • Data is not properly adjusted

    • mean, variance, correlation not adjusted for

    • further linear transformation of feature vectors may be necessary

    • further transformations my be necessary to adjust for categorical nature

    • SVD may eliminate more features


Next steps l.jpg
Next Steps

  • Further analysis of data

  • Further adjustments to MLP structure

  • Examine other pattern classifiers

    • K-nearest neighbor most intuitive

  • Compare with marketing research regression models
