三、Why do traditional CNN architectures underperform in classification tasks for a texture-based dataset? 传统的CNN架构通常包括预训练层,并在此基础上通过添加一些可训练的CNN块,然后将其输出传递到全连接层以进行类别预测,如图5所示。传统的CNN架构主要有四个组件,组件1输入层,组件2与训练层,组件3可训练的CN...
CNN outperforms than SVMas expected for the prepared dataset. CNN increases the overall classification performance around %7.7. In addition to that, the performance of each class is higher than %94. This result indicates that CNN can be used for defense system to meet the high precision require...
The turning point was in 2012, when Alex Krizhevsky, who was then a graduate student at the University of Toronto, used the CNN model to win that year’s ImageNet competition by dropping the classification error record from 26% to 15%—an astounding achievement at the time. For ...
Convolutional neural networks (CNN) can perform segmentation, classification, and detection for a myriad of applications: Segmentation: Image segmentation is about classifying pixels to belong to a certain category, such as a car, road, or pedestrian. It’s widely used in self-driving vehicle appli...
One method that uses Multi Image Dehazing is the CNN-basedRSDehazeNetmodel to remove haze from multispectral remote sensing data. RSDehazeNet consists of three types of modules: Channel Refinement Block or CRB, to model the interdependencies among the channel features since the channels of multispectr...

Our approach, called Gradient-weighted Class Activation Mapping (Grad-CAM), uses the class-specific gradient information flowing into the final convolutional layer of a CNN to produce a coarse localization map of the regions in the image important for each class. Grad-CAM is a strict ...
Also called Softmax Loss. It is aSoftmax activation plus a Cross-Entropy loss. If we use this loss, we will train a CNN to output a probability over the C classes for each image. What is the difference between categorical and Sparse_categorical_crossentropy?
Super-Resolution (SR) is a branch of Artificial Intelligence (AI) that aims to tackle this problem, whereby a given LR image can be upscaled to retrieve an image with higher resolution and thus more discernible details that can then be used in downstream tasks such as object classification,...
We use LSTM for the obvious reason that we are trying to predict time series data. Why we use GAN and specifically CNN as a discriminator? That is a good question: there are special sections on that later. We will go into greater details for each step, of course, but the most ...
