In this paper, a functional interface between brain and central pattern generator (CPG) is designed in an engineering perspective, which may serve in a human-machine system. Steady-state visual evoked potential (SSVEP) based brain-computer interface (BCI) is used to recognize five types of intention related to human walking. After feature extraction, classification and command translation on electroencephalography...
In this paper we design a multiple features template includes basic features, prefixes and suffixed features, dictionary features and combined features for Chinese named entity recognizer CRF model-based. We do a pre-processing procedure such as pos tag, chunk dictionary-based first. Then for dictionary features, different proportion of dictionaries are used in training and testing, which is different...
The proliferation of wireless localization technologies provides a promising future for serving human beings in indoor scenarios. Their applications include real-time tracking, activity recognition, health care, navigation, emergence detection, and target-of-interest monitoring, among others. Additionally, indoor localization technologies address the inefficiency of GPS (Global Positioning System)...
