Applying Newton's Law of Cooling to Transaction Scoring in DMP User Profiling

The article proposes using Newton’s law of cooling to score DMP user transactions, assigning higher weights to recent purchases that decay exponentially over time, deriving a cooling constant from boundary conditions, and normalizing the resulting heat‑based scores through log‑scaling and a sigmoid‑like mapping to a 0‑100 range.
