Artificial Intelligence / Unit 1 AI 0027 short lesson, about 20 seconds
Deterministic and Stochastic
Captions available
The idea
An environment is deterministic when each action has exactly one possible result, and stochastic when the same action can lead to different results.
In practice
An elevator button versus a bed of planted seeds: one action with one outcome, one action with a spread of outcomes.
Where people slip
Acting well under spread means comparing spreads, not lucky cases — arithmetic Unit 6 builds.
