The growing computational power and availability of large datasets have propelled ANN into a central role in artificial intelligence (AI).<\/p>\n<p>The primary objective of this research is to explore the theoretical foundation, applications, and challenges associated with ANN, as well as the future scope of this technology.<\/p>\n<p class=\"MsoNormal\"><!-- [if mso &amp; !supportInlineShapes &amp; supportFields]&gt;--><span><\/span><span>\u00a0<\/span>SHAPE <span>\u00a0<\/span>* MERGEFORMAT <span><\/span><!-- [if gte vml 1]&gt;--><\/p>\n<p><!-- [if !vml]--><!--[endif]--><!-- [if mso &amp; !supportInlineShapes &amp; supportFields]&gt;--><\/p>\n<p><span><\/span><\/p>\n<h2><strong><span style=\"font-family: 'Aptos Display',sans-serif\">Literature Review<\/span><\/strong><\/h2>\n<h3><strong><span style=\"font-family: 'Aptos',sans-serif\">Historical Background<\/span><\/strong><\/h3>\n<p>The foundation of ANNs was laid by McCulloch and Pitts (1943), who proposed the first mathematical model of a neuron. Later, Rosenblatt (1958) introduced the perceptron, which was one of the first machine learning models capable of performing classification tasks. The backpropagation algorithm, developed in the 1980s by Rumelhart, Hinton, and Williams (1986), significantly improved the training of multi-layer networks, leading to the rise of deep learning.<\/p>\n<h3><strong><span style=\"font-family: 'Aptos',sans-serif\">Recent Developments<\/span><\/strong><\/h3>\n<p>In recent years, architectures such as Convolutional Neural Networks (CNNs) (LeCun et al., 1998) and Recurrent Neural Networks (RNNs) (Hochreiter &amp; Schmidhuber, 1997) have revolutionized fields like image recognition and natural language processing. Transformer models, such as BERT (Devlin et al., 2018) and GPT (Brown et al., 2020), have further pushed the boundaries of ANN applications in language understanding.<\/p>\n<h2><strong><span style=\"font-family: 'Aptos Display',sans-serif\">Research Methodology<\/span><\/strong><\/h2>\n<p>This study is based on secondary research, including a review of peer-reviewed journal articles, conference papers, and books.

Architecture of ANN<\/span><\/strong><\/h3>\n<p>Artificial Neural Networks typically consist of three main layers:<\/p>\n<ul type=\"disc\">\n<li class=\"MsoNormal\" style=\"line-height: normal\"><strong><span style=\"font-family: 'Aptos',sans-serif\">Input Layer<\/span><\/strong><span>: Receives raw data inputs.<\/span><\/li>\n<li class=\"MsoNormal\" style=\"line-height: normal\"><strong><span style=\"font-family: 'Aptos',sans-serif\">Hidden Layers<\/span><\/strong><span>: Perform feature extraction and computations using activation functions like ReLU, Sigmoid, and Tanh.<\/span><\/li>\n<li class=\"MsoNormal\" style=\"line-height: normal\"><strong><span style=\"font-family: 'Aptos',sans-serif\">Output Layer<\/span><\/strong><span>: Provides the final result based on computed values.<\/span><\/li>\n<\/ul>\n<p>Each neuron in these layers is connected by weights that adjust during the learning process.
