  • Best Paper Award

    2018.3   WALCOM2018   We show that one of machine learning techniques called “boosting” can be efficiently computed over compressed data using non-determinist Zero-Suppressed Binary Decision Diagrams (ZDDs). A big advantage of this scheme is the ability to perform analysis using big data with minimal space. An interesting point in this research is that the combinatorial online prediction, a seemingly unrelated machine learning concept is successfully adopted for utilizing compressed data.

    本論文では,ZDDと呼ばれる圧縮データ構造を用いてデータを圧縮した上で,圧縮したデータ上でブースティングという機械学習手法が効率よく計算できる事を明らかにした.ビッグデータの解析において,省スペースで計算が出来ることは大きな利点である.
