“…The PCA components can be counted by X = YP , where X and Y are centering and input matrix, respectively and P is a matrix of eigenvector of the covariance vector matrix C x = PΛP T . Λ is a diagonal matrix whose diagonal elements are the eigenvalues corresponding to each eigenvector [19]. The new feature vectors are so-called principal components and arranged according to their variance (from largest to lowest).…”

“…Traditional methods, which have been developed to facilitate human activity recognition, are inside the range of supervised learning. For instance, the pervious methods include SVM [8] and Random Forest [9], which require to extract handcrafted features as the inputs of classifiers. Later, deep learning, and in particular, convolutional neural networks, has been diffusely used in the field of HAR.…”

“…A wide range of supervised methods commonly used for activity classification was reviewed in [Preece et al 2009;Peterek et al 2014]. One main characteristic of these methods is the necessity of a significant amount of labelled data to build the classification model.…”
