Binary Classification Model for MiniBooNE Particle Identification Using Python Take 1

Template Credit: Adapted from a template made available by Dr. Jason Brownlee of Machine Learning Mastery.

SUMMARY: The purpose of this project is to construct a prediction model using various machine learning algorithms and to document the end-to-end steps using a template. The MiniBooNE Particle Identification dataset is a classic binary classification situation where we are trying to predict one of the two possible outcomes.

INTRODUCTION: This dataset is taken from the MiniBooNE experiment and is used to distinguish electron neutrinos (signal) from muon neutrinos (background). The data file is set up as follows. In the first line is the number of signal events followed by the number of background events. The records with the signal events come first, followed by the background events. Each line, after the first line, has the 50 particle ID variables for one event.

ANALYSIS: The baseline performance of the machine learning algorithms achieved an average accuracy of 90.58%. Two algorithms (Bagged CART and Stochastic Gradient Boosting) achieved the top accuracy metrics after the first round of modeling. After a series of tuning trials, Stochastic Gradient Boosting turned in the top overall result and achieved an accuracy metric of 93.95%. By using the optimized parameters, the Stochastic Gradient Boosting algorithm processed the testing dataset with an accuracy of 93.85%, which was just slightly below than the training data.

CONCLUSION: For this iteration, the Stochastic Gradient Boosting algorithm achieved the best overall results using the training and testing datasets. For this dataset, the Stochastic Gradient Boosting algorithm should be considered for further modeling or production use.
