- binomial distribution: The chances of getting 0, 1, 2 and so on successes in a fixed number of tries, when every try has the same chance.
- distribution: A description of all the possible outcomes and how likely each one is.
- greedy decoding: Always picking the single most likely next word. Simple and repeatable, but it can sound flat or loop.
- Poisson distribution: The chances of a count of events in a fixed time, like sign-ups per hour, when they happen at a steady average rate.
- random variable: A number whose value depends on chance, like the number of heads in 10 coin flips.
