Predicting Event Attendance

Let me walk you through how I'd design a system to predict whether a the company user actually attended an event they RSVP'd to. I'll go stage by stage – business and ML objectives, high-level design, data and feature strategy, embeddings, pipeline architecture including modeling and training details, infrastructure, evaluation, and robustness. This is fundamentally a binary classification problem but with unique challenges around sparse ground truth, temporal dynamics, and the need to reason about real-world behavior from digital signals.
