Neural Style Transfer Web App (NeuralCeption)
Developed an end-to-end deep learning project to deploy Neural Style Transfer models directly in the browser, addressing significant resource constraints for client-side execution.
The Challenge
Deploying complex deep learning computer vision models directly within a web browser presents significant resource constraints. Models must be lightweight yet powerful enough to perform demanding tasks client-side. My goal was to explore how to successfully implement and optimize Neural Style Transfer under these limitations, enabling users to transform images with artistic styles directly in their browser using TensorFlow.js.
My Solution
This was an end-to-end project, from model design and tuning to browser deployment. I implemented various Neural Style Transfer models, including an adaptation of Johnson et al.'s approach utilizing perceptual loss. A key part of the solution involved optimizing model architecture to handle browser constraints, for instance, by replacing computationally expensive deconvolutions with more efficient bilinear upsampling and direct convolutions to avoid artifacts and improve performance.
The project culminated in a live web application, hosted on NeuralCeption, where users could experience real-time style transfer. Additionally, I provided a comprehensive repository allowing others to train and run these optimized models themselves, detailing the configuration, training, and inference steps. This project served to bridge advanced deep learning theory with practical, client-side application.
The Outcome
Successful Client-Side ML Deployment: Demonstrated the feasibility and optimization techniques for running deep learning computer vision models directly in a web browser.
Practical Problem-Solving: Identified and mitigated specific model limitations (e.g., checkerboard artifacts) through targeted architectural adjustments, leading to improved performance.
Knowledge Dissemination: Created a highly accessible web application and a detailed, runnable codebase, enabling a wider audience to explore and understand Neural Style Transfer firsthand.
End-to-End Development Expertise: Showcased capabilities across the entire ML lifecycle, from theoretical understanding and model implementation to optimization and web application deployment.
