SUMMARY: The project aims to construct a predictive model using various machine learning algorithms and document the end-to-end steps using a template. The Rice Varieties Identification dataset is a multi-class modeling situation where we attempt to predict one of several (more than two) possible outcomes.

INTRODUCTION: The dataset owner collected 75,000 pieces of rice grain and created a dataset that classifies the grains into one of the varieties (Arborio, Basmati, Ipsala, Jasmine, Karacadag). The research team applied various preprocessing operations to the rice images and obtained the features. Each record contains 106 attributes, including 12 morphological features, four shape features, and 90 color features obtained from five different color spaces (RGB, HSV, Lab*, YCbCr, XYZ).

ANALYSIS: The average performance of the machine learning algorithms achieved an accuracy benchmark of 99.75% using the training dataset. Furthermore, we selected Extra Trees as the final model as it processed the training dataset with a final accuracy score of 99.87%. When we processed the test dataset with the final model, the model achieved an accuracy score of 99.90%.

CONCLUSION: In this iteration, the Extra Trees model appeared to be a suitable algorithm for modeling this dataset.
