Human Activity Recognition (HAR) is leading-edge in today's research field which has its applications in multiple research areas, some of those are Smart Health, Security and Ambient Assisted Living, etc. In today’s ubiquitous computing, HAR can be accomplished by espousing deep learning techniques that replace traditional analytical techniques that depend on the extraction of handcrafted features and classification methods. This work employed the Hierarchical Multi Convolution—Extreme Learning Machine approach for the classification of human activities. In the Hierarchical Multi CNN approach, the root CNN is employed to categorize the activities into static and dynamic activities. In the next level, two CNN-ELM are used to classify static activities into laying down, stand and sit; and classifies dynamic activities into Walking, Walking Downstairs, and walking upstairs. CNN-ELM approach exhibits its major advantages: CNN extracts the features from the dataset which confiscates expert knowledge in extracting features and ELM classifies the transitional results. This framework is evaluated on the UCI-HAR dataset and achieves an accuracy of 96.86%. |
