The Hard Truth About Machine Learning for Amazon FBA Sellers

Amazon FBA demand forecasting breaks because the data is sparse, messy, and constantly shifting. Prophet and vanilla LSTMs often overfit and collapse under seasonality shifts. Real gains come from better feature engineering, TCNs with attention, Ray Tune + ASHA optimization, drift detection, and FBA-specific metrics like stockout penalties. In 2026, hybrid ML + RAG systems are becoming the only durable approach.
