Artificial neural networks (ANNs) are a cornerstone of modern AI, enabling systems to learn and make decisions based on data. Inspired by the structure of the human brain, ANNs consist of interconnected nodes (neurons) organized into layers. Each neuron processes inputs, applies an activation function, and passes the output to subsequent layers. This architecture allows ANNs to approximate complex functions and solve problems across domains. ANNs are particularly effective in tasks like image recognition, speech processing, and natural language understanding. For instance, convolutional neural networks (CNNs) specialize in visual data, while recurrent neural networks (RNNs) handle sequential data like time series or text. By enabling machines to learn patterns and relationships, ANNs power many AI applications, from chatbots to self-driving cars.
