for entropy reduction. pick up two lower probabilities first as a deepest branch. repeat it until you have built complete binary tree. then you can assign bit codes to each. less bit codes are assigned to frequently used data.
How do we derive the most compact codes for a situation? Huffman Trees can help. Professor Brailsford explains how computer scientists like their trees to be upside down. "Entropy in Compression - ...
