Dynamic AIFV coding using a dynamic Huffman code
Tomotaka Hiraoka, Hirosuke Yamamoto (The Univ. of Tokyo) IT2017-46
Abstract (in Japanese) (See Japanese page) 
(in English) Since AIFV codes attain better compression rate than Huffman codes, dynamic AIFV codes are expected to attain better compression rate than dynamic Huffman codes. In this paper, we show that a dynamic AIFV code can be constructed by combining Hu-Yamamoto-Honda's method to construct AIFV code trees from the Huffman code tree with a dynamic Huffman algorithm. In addition, for the case that Vitter's algorithm is used to update a dynamic Huffman code tree, we show by numerical experiments that our dynamic AIFV code can compress files better than the dynamic Huffman code if the probability distribution is largely biased in the files.
