stochastic
adjective
Meaning
Describing a process that involves a random variable or chance, often used to explain how AI models predict the next likely word or pixel based on probability rather than fixed rules. It is like a master chef who doesn't use a recipe but adds pinches of seasoning based on the 'vibe' of the pot, resulting in a slightly different but successful dish every time.
Etymology
From the Greek 'stochastikos', meaning 'aiming at a mark' or 'guessing', derived from 'stochos', a target.
Examples
"Large language models are fundamentally stochastic, which is why the same prompt can generate two unique and creative responses."
"The engineer explained that the stochastic nature of the algorithm allows the robot to navigate unpredictable terrain by constantly adjusting for chance obstacles."
