M.Tech Thesis: Invertible Neural Network (INN) to remove fences and obstructions from photos | Computer Vision | Tensorflow

• Designed a two-stage network: Stage 1: Created fence-shaped blank spaces with a GLOW prior for image inpainting.

Stage 2: Applied style transfer with two INNs to generate outputs with fences.

• Trained the model to implicitly learn the backward process of removing fences by training the simpler forward process of adding fences.
• Reduced computational costs while retaining full information during the removal process.

B.Tech Thesis: Social Media Rumor control system | MDP | Pytorch | R

· Analyzed and transformed a rumor control system from CCMAB to a Markovian Decision Process (MDP) for improved action optimization in evolving situations.

· Addressed complex environments and modeled delayed rewards and partial observability, suitablefor social media.

· Minimized cascading of sensitive information while preserving positive information diffusion and reduced computation costby approximately 10%.

Secure online voting protocol | Python | Flask | JavaScript | HTML| CSS| SSL

• Implemented Central Legitimization Agency (CLA) for voter verification and Central Tabulation Facility (CTF) for vote counting.
• Ensured secure server-client connections with SSL encryption.
• Applied and verified digital signatures using CLA and CTF private and public keys
• Provided a secure voting method, eliminating the need for physical presence.

Restaurant web application to demonstrate DBMS principles | Spring MVC | Java | Javascript | HTML | CSS

• Enabled web admins to manage manager information and food items.
• Allowed managers to post offers, view orders, and update delivery status.
• Provided customers with menu viewing, order placement, invoice generation.
• Facilitated customer feedback and collaboration requests for advertising.

Implemented database in third normal form (3NF) with role-based access permissions
