Image caption generation using enhanced Show, Attend, and Tell with BERT Context Vectors
Extended the "Show, Attend, and Tell" image captioning model by adding BERT, improving both the quality and speed of image captions. Used BERT's language features to make captions more accurate and context-aware. Reduced training time by leveraging BERT's pre-trained knowledge, allowing faster model convergence without losing accuracy. Showed how to combine advanced language understanding with image captioning to push the limits of AI-based image analysis.
Eventfly: An End-to-end Event Management System
Designed and developed a comprehensive microservices-based system to streamline event organization and participation. Led the back-end architecture and implemented key services, including newsfeed, payment, authentication, and event management.
