In entropy encoding, messages with higher probability are assigned shorter codes, while messages with lower probability are assigned longer codes. This is because assigning shorter codes to more probable messages allows for more efficient encoding, as these messages occur more frequently and thus require fewer bits to represent. On the other hand, assigning longer codes to less probable messages ensures that the encoding is still uniquely decodable, as longer codes are less likely to be encountered and are therefore less likely to cause ambiguity during decoding.

Prosečna količina informacije se računa kao suma verovatnoća svih mogućih događaja pomnožena sa negativnim logaritmom te verovatnoće. Što je veća entropija, to je veća nesigurnost ili neizvesnost u informacijama koje izvor generiše.

Poruka A ima verovatnocu ?, a poruka B ?

Kolicina informacije je veca u poruci A

Kolicina informacije je veca u poruci B

Kolicine informacije su jednake u obe poruke

The answer is that the quantity of information is greater in message A. This is because the question states that message A has a probability of ?, while message B has a probability of ?. Since the probabilities are not specified, we can assume that the probability of message A is higher than the probability of message B. In general, the higher the probability of an event, the less surprising or informative it is. Therefore, if the probability of message A is higher, it means that message A contains less surprising or expected information compared to message B, making the quantity of information greater in message A.

Za kompresiju podataka

Entropija izvora predstavlja fundamentalno ograničenje za kompresiju podataka. To znači da ne možemo komprimirati podatke ispod entropije izvora, jer bi to rezultiralo gubitkom informacija. Entropija izvora predstavlja meru neizvesnosti ili informacionog sadržaja izvora, i što je veća entropija, to su podaci manje predvidljivi i manje kompresibilni. Dakle, entropija izvora je bitna za određivanje optimalnih algoritama kompresije podataka.

The entropy of a binary source depends on the probabilities of the messages. The more probable a message is, the lower its entropy will be. This is because the entropy measures the average amount of information needed to represent a message from the source, and if a message is highly probable, it requires less information to represent it. Therefore, the probabilities of the messages directly affect the entropy of the binary source.

When we have coding for high-quality transmission in channel noise conditions, we add redundancy. Adding redundancy helps in error detection and correction, which improves the overall reliability of the transmission. By duplicating or adding extra bits to the original data, the receiver can identify and correct any errors that may have occurred during transmission. This ensures that the received data is as close to the original as possible, even in the presence of noise in the channel.
