用于Android手机活动识别的深度重构模型
Deep reconstruction models for activity recognition using Android Phones
摘要
Abstract
The activity recognition using Android phones is studied based on the assumption of the manifold-shaped data, and a deep reconstruction model ( DRM) which can learn the complex nonlinear curved surface structure and geo-metric features of current class samples without a priori assumption of basic geometry is proposed.Firstly, a tem-plate of the DRM is defined, and its parameters are initialized by performing the unsupervised pre-training in a lay-er-wise fashion using Gaussian restricted Boltzmann machines.In the training stage, the initialized DRM template is then separately trained for training the samples of each class and the class-specific DRMs are learnt.In the tes-ting stage, activities are recognized based on the minimum reconstruction error between the learnt class-specific models and the test samples.The experiment performed using the Android mobile phone dataset show that the cor-rect rate of this method for activity recognition is up to 99%.关键词
