• Diffusion Models: A Very Short Introduction to Diffusion Models

• Comparing MPC and PID controllers: a simple case.
  There is a trend that some of the PID controllers are being replaced by more advanced one, i.e., Model predictive controller (MPC). However, in what aspects that MPC would make improvement is not theoretically clear. As a starting point, the following dicussion aims to reveal the difference between the two controllers on first order systems. Follow-up: convert MPC (linear-quadratic) as SP/SQP optimization problem (link).
