probabilistic
意味: Based on or involving probability and statistical likelihood rather than certainty, describing methods, models, or reasoning that quantify uncertainty.
Probabilistic approaches acknowledge that perfect knowledge is often unattainable and instead assign likelihoods to different outcomes. Bayesian statistics, weather forecasting, medical diagnosis, and machine learning all employ probabilistic reasoning. The term is closely related to 'stochastic' but slightly broader: stochastic emphasises random processes, while probabilistic emphasises the use of probability theory in analysis and decision-making. It is standard vocabulary in academic and policy contexts.
