From the transcript

Sandeep, IEP ML engineer at a Toronto fintech, is proposing a new model architecture for fraud detection. Current model is gradient boosting; he wants to try a transformer-based approach. Design review with senior ML engineer (Maria), data scientist (Priya), and engineering manager (David). 60-90 minute meeting; Sandeep has 15 minutes to present, then Q&A.

Sandeep: Thanks everyone. I want to walk through my proposal for the next-generation fraud model. Goal is to share the rationale, get your pushback, and align on next steps. I'll take 15 minutes; then 30 minutes for questions.

Sandeep: Current state: our gradient boosting model achieves 0.87 AUC on validation. Production performance has…
