Pooling layers in CNN are designed to reduce the spatial dimensions (width and height) of the input volume. This reduction helps in decreasing the computational load, controlling overfitting, and making the network invariant to small transformations and distortions in the input image. Essentially, po...

This paper investigates the suitable position and number of pooling layers in Convolutional Neural Network (CNN) for script recognition from scene images. A common practice of CNN for object recognition is to position a convolve layer alternately with a pooling layer followed by a few layers of ...

Convolutional Neural Networks (CNNs) have recently been proposed as a solution in texture and material classification in computer vision. However, inside CNNs, the internal layers of pooling often cause a loss of information and, therefore, is detrimental to learning the architecture. Moreover, whe...
Convolutional layers in a convolutional neural network summarize the presence of features in an input image. A problem with the output feature maps is that they are sensitive to the location of the features in the input. One approach to address this sensitivity is to down sample the feature map...
池化层(Pooling layers) 除了卷积层,卷积网络也经常使用池化层来缩减模型的大小,提高计算速度,同时提高所提取特征的鲁棒性。 假如输入是一个 4×4 矩阵,用到的池化类型是最大池化( max pooling)。执行最大池化的树池是一个 2×2 矩阵。执行过程非常简单,把 4×4 的输入拆分成不同的区域,我把这个区域用不同...
Implementing CNN Structure This is the main structural part of CNN, where CNN is implemented, we have taken two convolutional layers and we can see we have added different activation functions like ReLU, sigmoid, and softmax function. Our structure goes in accordance with what we have a...
