Study Notes
Founding of Information Theory
- Established by Claude Shannon in the 1940s, building upon earlier work from the 1920s.
- The foundation focused on the representation, transmission, and processing of information.
Interdisciplinary Nature
- Information theory intersects with mathematics, computer science, and telecommunications.
- It plays a crucial role in data compression, error detection, and coding theory.
Concept of Entropy
- In information theory, entropy measures the amount of uncertainty or unpredictability associated with information content.
- Higher entropy indicates greater unpredictability, while lower entropy signifies more predictability.
Quantifying Uncertainty
- The measure that quantifies uncertainty in a random process is referred to as "entropy."
- It reflects the average amount of information produced by a stochastic source of data.
Examples of Information Content
- An example with less variability, such as flipping a coin that always lands on heads, provides lower entropy and less uncertainty.
- Conversely, an example with equal chances of heads or tails represents a higher entropy scenario.
