Professor Shinichi Yamagiwa (System Information Systems), University of Tsukuba and Professor Hiroshi Sakamoto (Graduate School of Information Engineering), Kyushu Institute of Technology, have announced a new lossless data compression technology for the big data era * "LCA-DLT (Lowest Common Ancestor-) Dynamic Lookup Table) ”was co-developed.
With this LCA-DLT technology, it is possible to significantly improve the amount of data transmission and transmission speed even with existing infrastructure, which can lead to cost reduction.In the future, it is expected to be applied to storage servers for "data centers" that store large amounts of data and wireless transmission of ultra-high-quality sound sources.
* Lossless data compression is a compression method in which compressed data is restored by decryption, and is also called lossless compression.On the other hand, image compression such as JPEG is called lossy compression and cannot be restored to the data before compression.
* Lifelog is a next-generation application that uses a wearable device to store information such as daily physical activities and behaviors, heartbeats and pulses as big data, and provides health management and lifestyle advice.
