Summary
Probability measures the probability of an event occurring, ranging from 0 (impossible) to 1 (certain). This concept became the basis of predictive models such as classification that resulted in the possibility of a particular class of data being included. Conditional probability describes the probability of an event given that another event has already occurred.
Key points
- The probability ranges from 0 (impossible) to 1 (certain).
- The probability of an impossible event is 0; the probability of a certain event is 1.
- P(A|B) is the probability A given that B has occurred.
- Events are mutually free when one does not affect the other.
- The classification of neural networks is often a probability per class.
