This tutorial details a sentiment analysis workflow using the IMDb Large Movie Review Dataset, comparing traditional TF-IDF and Logistic Regression methods with fine-tuned DistilBERT using LoRA. The process involves setting up the environment, auditing the dataset for potential issues, and evaluating models using various metrics like accuracy, F1-score, and ROC-AUC. The study also explores model interpretability through saliency maps and investigates the impact of context length limitations, concluding with a semi-supervised approach using pseudo-labeling on unlabeled data.
