I developed a real-time polynomial regression visualization that runs entirely in the browser using TensorFlow.js. The interactive demo allows users to click and drag to create data points, and watch as the model learns and adapts the polynomial curve in real-time. What makes this particularly special is how seamlessly it demonstrates complex mathematical concepts through intuitive visual interaction.
Building this project taught me so much about the intersection of web development and machine learning. Using TensorFlow.js, I implemented dynamic data collection through interactive point plotting with mouse events, real-time model training where the neural network updates as you add new data points, live visualization with smooth curve rendering that responds instantly to changes, and optimized performance with efficient tensor operations running at 60fps in the browser.
What excites me most about this project is how it demonstrates the power of client-side machine learning. No server required, no data leaving the user's device, yet we can perform sophisticated regression analysis with beautiful visualizations. This represents a fundamental shift in how we think about privacy-preserving machine learning and user experience design.
My technical stack consisted of TensorFlow.js for machine learning operations, HTML5 Canvas for smooth visualizations, vanilla JavaScript for DOM manipulation and event handling, and CSS3 for responsive design. I deliberately chose this minimal but powerful combination to keep the focus on the core functionality while ensuring broad browser compatibility.
The most challenging part was optimizing the training loop to maintain smooth 60fps performance while continuously updating the model. I learned to batch tensor operations and use TensorFlow.js's built-in optimizers effectively, which required deep diving into the framework's documentation and understanding the underlying WebGL operations that power browser-based machine learning.
