An Opinion on the General Formulation of Sequential Decision Problems

I came to control and reinforcement learning from chemical engineering, and in that passage the general formulation of the sequential decision problem was valuable to me, as a means of reading across fields in which I held no native vocabulary (thanks to legends like Dimitri Bertsekas and Warren Powell). However, for most researchers and practitioners, the object of interest is not the general formulation but the reduced problem that a particular field actually studies. ...

TEP Studio and Self-Describing Process Simulators

Dynamic process models are increasingly consumed by automated agents rather than by control engineers reading source code. These agents include data pipelines that assemble training sets, reinforcement-learning algorithms, and language models. Each depends on process meaning that a numerical interface does not expose, such as what each variable represents, which signals are available online, and which limits trigger a shutdown. Today that meaning lives in source code and informal convention, so recovering it is error-prone and does not transfer across a model’s many independent implementations. ...
