Question 1

What is Convolutional Neural Network?

Accepted Answer

A Convolutional Neural Network (CNN) is a type of deep learning model that is widely used in computer vision tasks such as image classification and object detection. It is designed to automatically learn and extract features from images, making it particularly effective in analyzing visual data.

The main building block of a CNN is the convolutional layer, which consists of various filters or kernels. These filters are small matrices that slide over the image, performing element-wise multiplication and summation to produce feature maps. This allows the network to capture local patterns and spatial relationships between pixels.

CNNs also utilize pooling layers, which reduce the dimensionality of the feature maps while retaining the most important information. This helps in reducing computational complexity and enhancing the network's ability to handle variations in input images.

Moreover, CNNs often include fully connected layers at the end, which act as classifiers or regressors to make predictions based on the extracted features. During the training process, the network learns to optimize the weights and biases of these layers through back propagation, enabling it to improve its accuracy over time.

Overall, Convolutional Neural Networks have revolutionized image recognition tasks by automating the feature extraction process and achieving remarkable performance in areas such as object detection, image segmentation, and facial recognition.
