متن کاملSchemes for Activity Recognition Systems Using PCA - WSVM , ICA - WSVM , and LDA - WSVM M ’ hamed
Feature extraction and classification are two key steps for activity recognition in a smart home environment. In this work, we used three methods for feature extraction: Principal Component Analysis (PCA), Independent Component Analysis (ICA), and Linear Discriminant Analysis (LDA). The new features selected by each method are then used as the inputs for a Weighted Support Vector Machines (WSVM...
متن کاملInterruption of Onchocerca volvulus transmission in the Abu Hamed focus, Sudan.
