Tatsuyuki reported on update of Hbb coupling measurement using BDT.

He added Mjj,higgs to the training input variables, and optimized BDT parameters.

Sigma(g)/g became better, 0.0067 (from 0.0071).

After the meeting, according to the suggestion from Uta, he added preselection Mjj,higgs>70 GeV, and Sigma(g)/g became 0.0068.
