  1. Wild Mushrooms Classification – Edible or Poisonous Yulin Shen ECE 539 Presentation 2013 Fall

  2. Mushroom is a kind of food with high nutrition, however, it is sometimes poisonous! • A classification problem. • Develop some models for prediction.

  3. Dataset is from UCI Machine Learning Repository About 8000 combinations Convert data into numerical form with an integral scale It can help to improve distances order for K-NN 4-way cross validation Get 4 pairs of datasets

  4. K-NN Classifier Euclidean distance Exhaustive K Determined by occurrences Naïve Bayer Classifier Each probability of features Compare positive and negative probabilities Some features have very high probabilities

  5. Results
