  1. Prediction of Wine Grade ECE 539: Intro to Artificial Neural Networks Matthew Kean

  2. Wine • Consumable product • Various physicochemical properties that contribute to the flavor of it (i.e. ABV, pH, sugar content, etc.) • Large market with significant competition to produce the best product

  3. Goal of this Work • Classification problem: determine the grade of a particular sample based only on the physicochemical properties • Use a MLP to get a better classification rate than KNN • If successful, the same method could be used for other consumable products

  4. Data Collection • Two different types of wine: one red and one white from a Portuguese vineyard • Retrieved from UC-Ivine database (http://archive.ics.uci.edu/ml/datasets/Wine+Quality) • 6000 samples total • 11 features for each sample, with none missing

  5. KNN • Used a KNN classifier to determine the benchmark for a multi-layer perceptron classifier • It had a peak value of 55% and an average classifying rate of 43%

  6. Results for the MLP • So far I have only been able to train MLPs with accuracies averaging 44% • No advantage over the KNN yet

  7. Other Work • By reducing the number of classes, a classification rate of over 90% was achieved • A different group obtained an 85% classification rate using a MLP, but they also got a slightly better classification rate using support vector machines.
