In this study,relevant work on autonomy evaluation(AE)in recent years was comprehensively reviewed and classified from the perspective of task models,and a closed-loop task models based theoretical framework for AE was developed.The main contributions of this study are as follows.1)A taxonomy for AE based on task models was introduced to classify current theories,methods and standards.2)The limitations of the current autonomous evaluation methods were addressed to provide a theoretical framework for quantitative evaluation based on task models,and evaluation metrics for each stage were proposed based on the AE theoretical framework.3)Qualitative analyses of the superiority of the proposed AE framework based on the closed-loop task models were conducted.This study attempts to provide a reference for researchers and engineers in the autonomous unmanned systems field and inspire future development of AE.
The purpose of this study is to examine the current situation of English writing autonomy and literacy among Chinese college students,to analyze their performance,scale,and distribution as well as influencing factors,and to explore the correlation between English writing autonomy and literacy.This study will provide an in-depth analysis of the current situation of Chinese college students’English writing autonomy and literacy,reveal the scale,distribution,and influencing factors,as well as put forward strategies to enhance them,so as to provide a reference for the reform and development of college English education.
