Should AI engineers be learning control theory basics alongside ML?

 Most AI failures are not model problems, they’re control problems.

In production systems, AI rarely fails because it gives a “wrong” answer. It fails because there is no feedback loop to correct behavior once things drift. Examples: A recommendation model that keeps amplifying noise A chatbot that becomes confidently wrong over time An autonomous system that optimizes speed but ignores stability In engineering terms, many AI systems are open-loop: Input → Model → Output No continuous correction No notion of system stability But reliable AI systems behave more like control systems: Observe → Decide → Act → Measure → Adjust This shift from prediction to control, is what will separate demos from dependable AI in robotics, transportation, and real-world automation. 👉 I write about AI from a systems & engineering lens here: Quora: Sibasis Padhi Question for the community: Should AI engineers be learning control theory basics alongside ML?

Yes, AI engineers should learn control theory basics alongside ML to build production-grade systems that maintain stability and adapt reliably.areasosta​

Why Control Theory Matters

Control theory provides tools for feedback loops, stability analysis (e.g., PID controllers, state-space models), and handling drift—directly addressing open-loop failures like amplifying noise or ignoring safety. ML excels at prediction but lacks inherent mechanisms for continuous correction; integrating concepts like observability and robustness turns models into closed-loop systems.non-compiti+1​

Practical Overlaps

• RL as Optimal Control: Reinforcement learning mirrors linear quadratic regulators (LQR), using value functions for policy optimization.latuascuolaonline​

• Stability Guarantees: Lyapunov methods ensure AI agents converge without oscillation, vital for robotics/autonomous driving.icmignanomlmarzano​

• Examples in Production: Tesla's FSD uses Kalman filters (control staples) for sensor fusion; recommendation systems apply feedback via bandit algorithms.areasosta​

Learning Path

• Start with basics: Feedback loops, Bode plots, PID tuning (MIT OCW 6.241).

• Apply to ML: Stable Diffusion's control via latent space dynamics; LangChain's agent loops.

• Resources: "Feedback Systems" by Åström (free PDF), "Control for AI" courses on Coursera.non-compiti​
