Could you please introduce the Major communication

networks used in computer networks?

Sure, the major communication networks used in computer networks are Local Area Networks (LANs), Wide Area Networks (WANs), Metropolitan Area Networks (MANs), and Storage Area Networks (SANs). These networks are used to facilitate communication between devices and enable the transfer of data over long distances.

Please introduce the SE module

The SE module refers to the Squeeze-and-Excitation module, which is a type of attention mechanism used in convolutional neural networks (CNNs) for image classification tasks. The SE module aims to adaptively recalibrate the importance of each feature map in a CNN based on its global context.

The SE module consists of two main operations: squeeze and excitation. In the squeeze operation, the feature maps are spatially averaged, which reduces the spatial dimensions to a single channel. In the excitation operation, the reduced feature maps are then passed through a set of fully connected layers, which learn to assign weights to each channel based on its importance to the task at hand.

The SE module can be added to any CNN architecture, and has been shown to improve the accuracy of image classification tasks, especially when dealing with large-scale datasets such as ImageNet.
