| Outline of Final Research Achievements |
The aim of this research is to produce a novel technology for stream data compression realizing the real time processing of stream data to obtain deep knowledge hidden big data stream. In the previous studies, because of the tradeoff between compression ratio and memory consumption, either algorithm requires so huge memory to load whole input or input data must be decomposed into a sequence of small segments so that the algorithm can load it into the restricted memory. In this proposal, we can minimize the nonnegligible tradeoff, and we can expand the throughput of the network constructed by the compression-transmission-decompression algorithm implemented by FPGA. We propose and demonstrate these outcomes to the real world via patent applications, research articles, and industrial demonstrations.
