recent research field cognitive motor action decoding focuses data acquired functional nearinfrared spectroscopy fnirs analysis research aims classify two different motor activities namely mental drawing md spatial navigation sn using fnirs data nonmotor baseline data motor activities accurate activity detection nonstationary signals like fnirs challenging requires complex feature descriptors novel framework new feature generation fusion wavelet feature hilbert symlet hjorth parameters proposed improving accuracy classification new fused feature statistical descriptor elements timelocalization frequency domain edge feature texture features phase information detect locate activity accurately three types independent component analysis including fastica picard infomax implemented preprocessing removes noises motion artifacts two independent binary classifiers designed handle complexity classification one responsible mental drawing md detection one spatial navigation sn four different types algorithms including nearest neighbors knn linear discriminant analysis lda light gradientboosting machine lgbm extreme gradient boosting xgboost implemented identified lgbm classifier gives high accuracies98 mental drawing 97 spatial navigation comparison existing research proves proposed method gives highest classification accuracies statistical validation proposed new feature generation kruskalwallis htest mannwhitney u nonparametric test proves reliability proposed mechanism
