This project delved into the application of natural language processing (NLP) techniques for classifying sentiment (positive or negative) within movie reviews. Leveraging key libraries like scikit-learn, NLTK, and Pandas, I meticulously preprocessed the text data, including tokenization, stop word removal, and stemming. To extract meaningful features, I employed the Term Frequency-Inverse Document Frequency (TF-IDF) weighting scheme.

Extensive model exploration revealed a tie between two top performers Support Vector Machines (SVM) with both linear and RBF kernels achieved an impressive accuracy of 89.9%. Due to its simplicity and ease of deployment, I prioritized the linear SVM as the best model. Analysis of the confusion matrix highlights a subtle bias towards positive classifications, presenting an interesting area for further optimization and potential exploration of techniques to address class imbalance.

StudyBuddy AI is an innovative educational platform designed to revolutionize the way students learn and interact with study materials. Leveraging React for a dynamic frontend and Cloudflare Workers for a serverless backend, this project seamlessly integrates Anthropic’s Claude AI model to provide intelligent, context-aware study assistance. The application offers personalized learning experiences, real-time explanations across various subjects, and chat-based interactions for in-depth topic exploration.

A key technical challenge was implementing a scalable architecture capable of handling real-time AI interactions while maintaining low latency. This was achieved through strategic use of Cloudflare Workers and D1 database for efficient data management and API routing. The project features a sophisticated user authentication system with tiered access levels, integrated with Stripe for seamless subscription management. The application includes features such as chat history management, PDF document analysis, and adaptive responses based on user subscription levels. Ongoing development focuses on enhancing the AI’s contextual understanding of educational content and implementing advanced analytics to track and optimize user learning paths.
