Blahut–Arimoto algorithm
So imagine you are trying to talk with your friend who is very far away and you can only use a set of symbols like letters or numbers to communicate your message.
But you only have a limited amount of symbols to use, so you need to be able to encode your message using those symbols in the most efficient way possible, so that you can fit as much information as you can in the limited space you have.
The Blahut-Arimoto algorithm helps you find the best way to encode your message using those symbols. It does this by trying out different encoding schemes and calculating how much information can be transmitted using each of them.
It then picks the encoding scheme that allows you to transmit the maximum amount of information possible with the least number of symbols. This way, you can save space, time and effort when communicating with your friend or any other person over a distance.
