Music Emotion Classification Method Based on Deep Learning and Explicit Sparse Attention Network.

In order to improve the accuracy of music emotion recognition and classification, this study combines an explicit sparse attention network with deep learning and proposes an effective emotion recognition and classification method for complex music data sets. First, the method uses fine-grained segmentation and other methods to preprocess the sample data set, so as to provide a high-quality input data sample set for the classification model. The explicit sparse attention network is introduced into the deep learning network to reduce the influence of irrelevant information on the recognition results and improve the emotion classification and recognition ability of music sample data set.

Biocontrol mechanism of Myxococcus xanthus B25-I-1 against Phytophthora infestans.

Phytophthora infestans is the pathogen causing potato late blight, one of the most serious diseases of potato. Myxobacteria have become a valuable biological control resource due to their preponderant abilities to produce various secondary metabolites with novel structure and remarkable biological activity. In this study, Myxococcus xanthus strain B25-I-1, which exhibited strong antagonistic activity against P.
