System ? Motivation Influenced Melody Influencer Melodies Inputs Similarity Measurement Output

Background Bayesian reasoning: ▫Surface. ▫Structure. Markov chains. Logistic regression.

System ? Proposed Model Influenced Melody Influencer Melodies Inputs Similarity Measurement Output

Predictors Logistic Regression Use output from the probability estimator to “classify” the influenced artist’s melody. Training is needed. Picture from

Limitations Implementation currently underway. Limited information in melodies. Small numbers in probability estimator. Some subjectivity.
