Abstract Brain-Computer Interface (BCI) is a communication tool between humans and systems using electroencephalography (EEG) to predict certain cognitive state aspects, such as attention or emotion. For brainwave recording, there are many types of acquisition devices created for different purposes. The wet system conducts the recording with electrode gel and can obtain high-quality brainwave signals, while the dry system expressly proposes the practical and ease of use. In this paper, we study a comparative study of wet and dry systems using two cognitive tasks: attention and music-emotion. The 3-back task is used as an assessment to measure attention and working memory in attention studies. Comparatively, the music-emotion experiments are used to predict the emotion according to the subject's questionnaires. Our analysis shows the similarities and differences between dry and wet electrodes by calculating the statistical values and frequency bands. Besides, we further study the relative characteristics by conducting the classification experiments. We proposed the end-to-end models of EEG classification, which are constructed by combining EEG-based feature extractors and classification networks. A deep convolution neural network (Deep ConvNet) and a shallow convolution neural network (Shallow ConvNet) were applied as the feature extractor of temporal and spatial filtering from raw EEG signals. The extracted feature is then forwardly conveyed to a long short-term memory ( LSTM ) to learn the dependencies of convolved features and classify attention states or emotional states. Additionally, transfer learning was utilized to improve the performance of the dry system by using transferred knowledge from the wet system. We applied the model not only on our dataset but also on the existing dataset to verify the model performance compared with the baseline techniques and the-state-of-the-art models. Using our proposed model, the result shows the significant differences between accuracy and chance level in attention classification (92.0%, S.D. 6.8%) and SEED dataset's emotion classification (75.3%, S.D. 9.3%).

In order to solve the problem that the existing deep learning method has insufficient ability in feature extraction in the text emotion classification task, this paper proposes a text emotion analysis using the dual-channel convolution neural network in the social network. First, a double-channel convolutional neural network is constructed. Combined with emotion words, parts of speech, degree adverbs, negative words, punctuation, and other word features that affect the text’s emotional tendency, an extended text feature is formed. Then, using the CNN’s multichannel mechanism, the extended text features based on the word vector features and the semantic features based on the word vectors are, respectively, input into the CNN model. After each convolution operation of the convolution channel, the BN technology is used to normalize the internal data of the network and the padding technology is used to improve the ability of the model to extract edge features of the data and the speed of the model. Finally, a dynamic k-max continuous pooling strategy is adopted to realize the dimensionality reduction of features and enhance the model’s ability to extract features. The experimental results show that the accuracy and F1 values obtained by the proposed method can be as high as 94.16% and 92.61%, respectively, which are better than several comparison algorithms.

Damage of blood vessels in retina due to diabetes is known as diabetic retinopathy. It is one of the one of the important origins of blindness for adults. Loss of vision can be avoided by detecting damage of retina (leaking fluid or blood). Efficient local cloud-based solution for diabetic retinopathy detection is designed in the work, where convolution neural network is used for training and classification module and achieved an accuracy of 86% using kappa metric. Fundus images are used for training and classification. System network architecture is derived from VGGNet. Network is trained using 80,000 images. Since everything is automated, a doctor is only required for treatment, not for diagnosis.
