Recognizing mixed urban functions from human activities using representation learning methods被引量：3
《International Journal of Digital Earth》2023年第1期289-307,共19页Junjie Hu Yong Gao Xuechen Wang Yu Liu 
supported by the National Natural Science Foundation of China[grant number 41971331].
When various urban functions are integrated into one location,they form a mixture of functions.The emerging big data promote an alternative way to identify mixed functions.However,current methods are largely unable to...

Investigating Neural Representation of Finger-Movement Directions Using Electroencephalography Independent Components
《Journal of Biomedical Science and Engineering》2021年第6期240-265,共26页Mohamed Mounir Tellache Hiroyuki Kambara Yasuharu Koike Makoto Miyakoshi Natsue Yoshimura 
There are few EEG studies on finger movement directions because ocular artifacts also convey directional information, which makes it hard to separate the contribution of EEG from tha...
