Activity recognition (AR) is the basis for many applications concerning health care
sports
security and gaming industry. Traditionally
batching learning recognition algorithms is adopted to train network. However
the amount of data is considerable and not all training data arrives instantly
the learning procedure is time-consuming and the network weights cannot be updated online. In this paper
Classification of the human activities is performed with Online Sequential Kernel Extreme Learning Machine (OS-KELM). The method of feature selection based on Fisher criterion and feature clustering has been adopted to reduce difficulty and improve efficiency of learning. A tri-axial accelerometer and gyros data from a users smart phone are used to recognize walking
waling downstairs
walking upstairs
standing
sitting and laying. Experimental results with an average accuracy of 91.89% are achieved.
