HSI analysis suffers from overfitting due to the limited number of labelled training samples. As a result, in order to enhance the performance of the HSI classification task, a better efficient neural network architecture should be developed. To tackle this issue, this letter presents a new 3D-Inception CNN (3D-ICNN) model for dynamically extracting features by stacking inception modules in the network that can learn more representative features with fewer training samples by adopting variable spatial size convolutional filters and dynamic CNN architecture. The experimental results exhibit that the presented model can modify the network design adaptively and achieve higher classification performance. To establish the efficiency and robustness of the presented model, the experiments are conducted on the publicly available benchmark data sets and also on the new data sets. The proposed 3D-Inception CNN model obtained accuracies of 86.25% on Ahmedabad-1(AH1) dataset, 80.30% on Ahmedabad-2(AH2) dataset, 99.95% on the Pavia University (PU) dataset, 99.86% on the Salinas (SA) dataset, and 99.89% on the Indian Pines (IP) dataset.

However, due to the high dimensionality of HSI data and the limited number of labelled examples available, conducting HSI image classification poses significant technical and pragmatic hurdles. Approaches to HSI classification with deep learning have gained major successes in recent years as new deep learning algorithms emerge, giving unique prospects for hyperspectral image classification research and development. Initially, a quick introduction to standard deep learning (DL) models is provided, followed by a comparison of the performance of common DL based HSI approaches. Finally, the difficulties and future research prospects are explored.

The large-scale hyperspectral image data leads to many processing challenges for the conventional data analysis techniques. To minimize the computational complexity and enhance the classification performance of the HSI dataset, we presented a new hybrid learning technique for feature extraction and classification (Hybrid-LN) model in this work. It is a simple two-step approach, to reduce computational complexity, the first step is applied to generate a spatial-spectral reduced HSI dataset by identifying the most significant pixels from each class and the most significant bands of the HSI. To increase HSI classification performance, the second step involves training a CNN to extract spatial-spectral features from the reduced HSI. Results from three benchmark HSI datasets-Salinas scene (SA), Indian Pines (IP), and Pavia University scene (PU)-are compared to those from the current models. Experimental results show that the computational complexity of the proposed approach is significantly reduced and producing relatively good classification accuracy with the state-of-the-art methods.

Important among machine learning tasks is classification involving the process of training machines to make predictions from predefined labels. Classification is broadly categorized into three distinct groups: single-label (SL), multi-class, and multi-label (ML) classification. This research work presents an application of a multi-label classification (MLC) technique in automating Quranic verses labeling. MLC has been gaining attention in recent years. This is due to the increasing amount of works based on real-world classification problems of multi-label data. In traditional classification problems, patterns are associated with a single-label from a set of disjoint labels. However, in MLC, an instance of data is associated with a set of labels. In this paper, three standard MLC methods: binary relevan...

High classification accuracy has been achieved by extracting deep features from both spatial-spectral channels. However, the efficiency of such spatial-spectral approaches depends on the spatial dimension of each patch and there is no theoretically valid approach to find the optimum spatial dimension to be considered. It is more valid to extract spatial features by considering varying neighborhood scales in spatial dimensions. In this regard, this article proposes a deep convolutional neural network (CNN) model wherein three different multi-scale spatial-spectral patches are used to extract the features in both the spatial and spectral channels. In order to extract these potential features, the proposed deep learning architecture takes three patches various scales in spatial dimension. 3D convolution is performed on each selected patch and the process runs through entire ...
