Introduction

Emergence of artificial intelligence (AI) has made machines “Smart.” By “Smart,” we mean the ability of the machine (possibly a computer) to process the given data with rationality, like an intelligent human being, and take a suitable decision. AI achieves this intelligence with the help of its subsets of algorithms (see Figure 1.1).

Figure 1.1 Subsets of Artificial Intelligence

AI is a broader field that includes machine learning (ML), artificial neural network (ANN), and deep learning (DL) as its subsets. AI is achieved by ANN, which is a network of artificial neurons resembling a biological neuron and the nervous system. ML enables the machines to process the data, make decision, and optimize the results based on experience. ML primarily requires a feature engineer to do the feature engineering process. Also, ML works its best for structured dataset (mostly comprises numerical data) but is proven inefficient for unstructured types.

To process the unstructured and continuous data like video, speech, etc., we need more complex neural network. Here comes in the DL with better results on processing the unstructured data. One of the biggest advantages of DL is that it features engineering automatically, that is, no manual feature selection is required. Also, ML requires manual intervention when the algorithm is struck with optimization problem, which is also automated in DL. DL plays the key role in implementing and visualizing the actual AI. Deep learning, however, requires a large amount of dataset for the purpose of training, which in turn requires a deep network of layers of neurons to process the features and hence the name “deep learning.”

DL comprises many algorithms for different types of data. Of those, convolutional neural network (CNN) is mainly used to process images and solve computer vision problems. The idea of CNNs can be traced back to 1980, when K. Fakushima proposed “neocognition” – a hierarchical multi-layered neural networks, which is self-organized and unaffected by the translation operation in the dataset (shift in positions of patterns). It was primarily created for pattern recognition.

The first standard CONVNet was introduced by Yann LeCunn in 1998, in his research article titled “Object Recognition with Gradient Based Learning.” It is important to note that Yann LeCunn has cited Fakushima’s article in his research work, and the CONVNet of LeCunn has a structure similar to neocognition with back propagation added to the network. Thenceforth, multiple improvements and the extension were made to it.

Convolutional Neural Network (CNN)

Convolutional neural network is primarily used for operations like image classification, segmentation, and other computer vision operations. CNN is also called shape/space invariant artificial neural network (SIAAN) based on its shared weights and translation invariance properties. The key idea behind CNN is to capture the local patterns through convolution operation.

In general, each CNN architecture has a common working flow. A CNN consists of multiple layers of convolution and pooling and a fully connected ANN. A layer in CNN may comprise one convolution layer and one pooling layer together as a single layer if the count of convolution layer and pooling layer is same. Most commonly used type is two convolution layers followed by a single pooling layer.

The number of layers in a CNN architecture depends on the complexity of the application. The output of the last layer is passed to an ANN. The convolution layers and the pooling layers always perform the same operation of learning the input image. The fully connected networks perform the required operations, such as regression, classification, etc.

At each convolution layer, a local pattern is obtained by applying filters throughout the image. Filters can also be mentioned as kernels. The Initial/lower-level layers of the CNN obtain the elementary pattern of the image ...
