AI in POS and Payments: From Transaction Processing to Transaction Intelligence

This post looks at where machine learning actually fits in a payment system: not inside the authorization path that EMV, tokenization, and the networks already own, but in the risk …

Maximum Entropy Inverse Reinforcement Learning: Understanding the Trajectory Formula

Inverse reinforcement learning (IRL) asks a different question from classical RL: instead of assuming a reward function and learning a policy, you observe expert behavior and infer …

I Spent Years on Adaptive Filters. I Was Already Training Neural Networks.

I spent years implementing LMS-based equalizers and echo cancellers in telecommunications. Only later did I fully appreciate what I had been doing mathematically: the same family …

Feasibility Assessment: Q-Learning Suitability for Organizational Decision Systems

Q-learning for production decision systems: when tabular or deep Q-networks (DQN) make sense, state–action limits, stationarity, exploration cost, convergence risks—and when to say …
