What is DNN (Deep Neural Network)?
A Deep Neural Network (DNN) is a class of artificial neural networks distinguished by its architecture, which features multiple layers between the input and output layers. These hidden layers enable the network to learn intricate patterns and representations from raw data, making DNNs highly effective for complex computational tasks.
DNNs are a fundamental component of deep learning, a subfield of machine learning that focuses on algorithms inspired by the structure and function of the human brain. The ‘deep’ aspect refers to the number of hidden layers, typically exceeding two, which allows for hierarchical feature extraction and more abstract data processing.
The development and application of DNNs have revolutionized various fields, including artificial intelligence, computer vision, natural language processing, and predictive analytics. Their capacity to process vast datasets and identify subtle correlations has led to breakthroughs previously considered unattainable.

Understanding DNN (Deep Neural Network)
Deep Neural Networks are structured as a series of interconnected layers: an input layer, several hidden layers, and an output layer. Each layer consists of nodes (neurons) that receive input from the previous layer, perform a weighted sum, and apply an activation function before passing the output to the next layer.
