About

This canvas implements a complete end-to-end autonomous RTB (real-time bidding) system called Aegis-RTB that combines probabilistic conversion modeling with contextual bandit optimization. The workflow streams the Criteo dataset (200K impressions), engineers privacy-preserving features via hashing and normalization, trains a calibrated pCVR model using Gradient Boosting, implements a LinUCB bandit for adaptive bid adjustments, and validates the system through tournament simulations showing 280% ROI improvement over flat bidding strategies. The system produces inference-ready models, comprehensive performance documentation, and an API-ready bid decision engine delivering optimal bids in <2ms with 95.7% AUC accuracy.
