Can you explain entropy in information theory?
Sure! In information theory, entropy is a measure of uncertainty or randomness in a set of data. It quantifies the amount of information that is produced when an event occurs.
How is entropy calculated?
Entropy is calculated using the formula: H(X) = -Σ p(x) log₂ p(x), where p(x) is the probability of each event x occurring.
What does a high entropy value indicate?
A high entropy value indicates a high level of uncertainty or unpredictability in the data, meaning the information is more diverse.
Can you give an example of entropy in real life?
Certainly! Consider a fair coin toss. The entropy is high because the outcome is uncertain (heads or tails). In contrast, a biased coin has lower entropy.
