Three-Dimensional ResNeXt Network Using Feature Fusion and Label Smoothing for Hyperspectral Image Classification

Abstract: In recent years, deep learning methods have been widely used in the hyperspectral image (HSI) classification tasks. Among them, spectral-spatial combined methods based on the three-dimensional (3-D) convolution have shown good performance. However, because of the three-dimensional convolution, increasing network depth will result in a dramatic rise in the number of parameters. In addition, the previous methods do not make full use of spectral information. They mostly use the data after dimensionality reduction… Show more

“…We compared the diagnostic performance of our model with the four machine learning algorithms which are currently most popular and advanced, including ResNeXt [14], SE_Inception_v4 [15], SE_Net [16] and Xception [17]. These models are widely used in the field of AI of medical images [18,19]. The 3000 ultrasound images randomly selected from the test set in Center 1 were used for this part of the study.…”

“…In 2017, Huang et al [ 9 ] proposed DenseNet, which made it possible for feature reusing and provided another way for feature fusion, which is realized by the concatenation of different feature maps. In recent years, the above mentioned two feature fusion methods, which are proposed in ResNet and DenseNet, that have been widely used in the tasks of image classification [ 10 , 11 ], semantic segmentation [ 12 , 13 ], object detection [ 14 , 15 ], etc. Additionally, they are served as the standard patterns of feature extraction based on CNN.…”
