When Circuits Didn't Work and What It Taught Me About AI
The article explores the author's experience with unpredictable circuit behavior during their engineering studies, and how it relates to the complexity and sensitivity of large language models (LLMs) in AI.
Why it matters
This article provides valuable insights into the nature of complex systems, both in the physical and digital realms, and how understanding their sensitivity and unpredictability is crucial for working effectively with technologies like AI.
Key Points
- 1Circuits sometimes behaved unexpectedly, even when everything seemed correct
- 2Small, invisible factors like electrical noise, voltage variations, and internal states influenced the circuit's behavior
- 3Similarly, LLMs can produce vastly different responses to minor changes in prompts, exhibiting complex and non-deterministic behavior
- 4The author learned that complex systems are not always perfectly predictable
Details
The article describes the author's experience with circuits that would suddenly start working, even without any significant changes. They realized that small, invisible factors like loose connections, electrical noise, and internal states were influencing the circuit's behavior in unpredictable ways. Years later, the author encountered a similar phenomenon when working with large language models (LLMs) in AI. Minor changes to prompts would lead to drastically different responses, sometimes brilliant and sometimes completely off-base. The author draws a parallel between the sensitivity of circuits and the complexity of LLMs, noting that both are influenced by factors that are not always visible or easily predictable. This experience taught the author that complex systems, whether physical or digital, do not always behave in a perfectly deterministic manner, and that learning to work with this inherent unpredictability is a key part of engineering.
