What is a probabilistic?
In general, any situation in which decisions are made based on likelihoods or odds.
probabilistic explained in plain English
In general, any situation in which decisions are made based on likelihoods or odds. LLMs are probabilistic systems, generating the next word or sentence in a response based on probabilities. If the temperature is relatively low, an LLM will choose words or sentences having high probabilities. If the temperature is relatively high, an LLM will be more "creative," sometimes choosing words or sentences having lower probabilities.
Example
Practitioners refer to probabilistic when building, training, or evaluating machine learning systems. It appears in research papers, product documentation, and technical discussions about AI capabilities and limitations.
