In recent years, convolutional neural networks have been widely used in various fields of computer vision and achieved remarkable results. Regularization method is an important part of convolutional neural network, which helps to avoid the overfitting phenomenon of convolutional neural network in the process of model training. There are fewer reviews on regularization methods for convolutional neural networks, and most of them lack a summary of the newly proposed regularization methods. Firstly, this paper conducted a detailed summary of the literature on regularization methods in convolutional neural networks, and classified the regularization methods into parameter regularization, data regularization, label regularization and combinatorial regularization. After that, on the public datasets such as ImageNet, it compared and analyzed the advantages and disadvantages of different regularization methods based on evaluation indexes such as top-1 accuracy and top-5 accuracy. Finally, it discussed the future research trends and work directions of regularization methods for convolutional neural network. [ABSTRACT FROM AUTHOR]

【Objective】 The present study was conducted to investigate effects of long-term fertilization on soil organic carbon(SOC) and total nitrogen(TN) and evaluate fertilizer application. 【Method】 Based on the long-term fertilization experiment, effects of various fertilization practices on SOC and TN in the surface(0-20 cm) and subsurface(20-40 cm) purple soil in Southwest China were studied.【Result】SOC content in the CK treatment showeda decreasing trend, and the decrease rate was 0.033 g/kg. But the SOC content of all the fertilization treatments demonstrated an increase trend, and the increase rate were 00.047 and 0.085 g/kg in the chemical fertilizers(N, NP, NPK) and the combined application of organic manure and chemical fertilizers(MN, MNP, MNPK), respectively. TN content of CK, chemical fertilizers and chemical fertilizers plus organic manure increased yearly 0.0058, 0.011 and 0.018 g/kg, respectively. The long-term application of fertilizers, especially the combination of chemical fertilizers and organic manure significantly increased SOC and TN in the surface and subsurface soil. Compared with the CK, application of chemical fertilizers and chemical fertilizers plus organic manure increased SOC content by 30.40%, 44.69%, 11.83% and 19.29%, SOC storage by 32.30%, 42.87%, 19.09% and 24.96%, TN content by 13.39%, 29.29%, 8.33% and 1.04%, and TN storage by 15.43%, 28.29%, 15.22% and 5.07% in the surface and subsurface soil, respectively. There was a positive correlation between C and N content. 【Conclusion】 Application of chemical fertilizers plus organic manure was recommended in the purple paddy soil area. [ABSTRACT FROM AUTHOR]

A field experiment was carried out to investigate the effects of different combinations of organic and mineral fertilizers on yield, nutritional and safety quality of long chili pepper and to offer science-based fertilizer recommendations for high yield and quality chili pepper production in Sichuan. The results showed that the chili yield was increased by 10% with combined use of organic and mineral fertilizers compared to use of mineral fertilizers only, a yield increase by 15.34% with pig manure and by 14.86% with rapeseed meal. Combined use of organic and mineral fertilizers had little effect on vitamin C content in chili pepper, but significantly increased contents of amino acids, 2.13 g/kg higher than the mineral fertilizers only. Amino acids in chili were increased by 20.92% with pig manure and by 15.82% with rapeseed meal. Nitrate content in the chili pepper of the organic and mineral fertilizers combined treatments was decreased by 74.57% compared to the mineral fertilizers only. The rapeseed meal treatment had the lowest nitrate content among all. It is concluded that pig manure and rapeseed meal are the most suitable organic fertilizers for high yield and quality long chili pepper production, and combined use of organic and mineral fertilizers resulted in the best.
