What is the purpose of max pooling in a CNN?
Max pooling is a critical operation in Convolutional Neural Networks (CNNs) that plays a significant role in feature extraction and dimensionality reduction. In the context of image classification tasks, max pooling is applied after convolutional layers to downsample the feature maps, which helps in retaining the important features while reducing computational complexity. The primary purpose

How is the feature extraction process in a convolutional neural network (CNN) applied to image recognition?
Feature extraction is a crucial step in the convolutional neural network (CNN) process applied to image recognition tasks. In CNNs, the feature extraction process involves the extraction of meaningful features from input images to facilitate accurate classification. This process is essential as raw pixel values from images are not directly suitable for classification tasks. By
What is the purpose of using the softmax activation function in the output layer of the neural network model?
The purpose of using the softmax activation function in the output layer of a neural network model is to convert the outputs of the previous layer into a probability distribution over multiple classes. This activation function is particularly useful in classification tasks where the goal is to assign an input to one of several possible
Why is it necessary to normalize the pixel values before training the model?
Normalizing pixel values before training a model is a crucial step in the field of Artificial Intelligence, specifically in the context of image classification using TensorFlow. This process involves transforming the pixel values of an image to a standardized range, typically between 0 and 1 or -1 and 1. Normalization is necessary for several reasons,
