Question

In 2023, DeepMind researchers showed that Chinchilla LLMs performing an “arithmetic” technique can surprisingly outperform standard algorithms for this task. Most modern algorithms for this task use discrete cosine (15[1])transforms then impose a cutoff (15[1])frequency. One iteratively finds the longest string in a table that is the prefix of an unscanned input in the (*) Lempel-Ziv algorithm for this task. Shannon entropy provides a theoretical limit on this task according to Shannon’s source (-5[1])coding theorem. A binary tree based on relative symbol frequency is used to construct a Huffman code for this task. The conversion of images to JPEGs exemplifies the lossy form of, for 10 points, what task in computer science which reduces the size of a data file? (10[2])■END■

ANSWER: data compression [accept source coding; accept bit-rate reduction]
