In this solution for COMP 4446/5046 Assignment 1 by YOUR_UNIKEY, we discuss the implementation of a classifier for sentiment analysis on movie reviews. The implementation uses the IMDB movie review dataset, preprocesses the data and applies various machine learning methods to classify the reviews as positive or negative. We discuss the process of data cleaning, feature extraction, model selection, hyperparameters tuning and evaluation of the model. The best results were achieved using the SVM classifier with an accuracy of 89%.
