Abstract. Effective discrimination of attention deficit hyperactivity disorder (ADHD) using imaging and functional biomarkers would have fundamental influence on public health. In this paper, we created a classification model using ADHD-200 dataset focusing on resting state functional magnetic resonance imaging. We predicted ADHD status and subtype by deep belief network (DBN). In the data preprocessing stage, in order to reduce the high dimension of fMRI brain data, brodmann mask, Fast Fourier Transform algorithm (FFT) and max-pooling of frequencies are applied respectively. Experimental results indicate that our method has a good discrimination effect, and outperform the results of the ADHD-200 competition. Meanwhile, our results conform to the biological research that there exists discrepancy in prefrontal cortex and cingulate cortex. As far as we know, it is the first time that the deep learning method has been used for the discrimination of ADHD with fMRI data.
At present, the wave of globalization has swept the world and penetrated into all aspects of social life, bringing opportunities and challenges. In the context of economic and technological globalization, the concept of internationalization of scientific and technological innovation has emerged as the times require. It has become an important strategic means for countries to adapt to globalization trends, respond to globalization challenges, and seize globalization opportunities. In recent years, the internationalization of scientific and technological innovation has increasingly become an important issue of concern to the provincial government. In order to further integrate deeply into the global innovation network, maximize the use of international scientific and technological resources, and strive to achieve new breakthroughs in becoming the forefront of innovative provinces and building an open innovation highland, this paper constructs the internationalization system of scientific and technological innovation in Shandong Province, and puts forward countermeasures and guarantee measures to promote the internationalization of scientific and technological innovation in Shandong Province.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
