A neural network in Artificial Intelligence (AI) is a computational model inspired by the structure and functioning of biological neural networks in the human brain. It is used to recognize patterns, make predictions, and solve complex problems by mimicking how the brain processes information.

Key Components of a Neural Network:

1. Neurons (Nodes): These are the basic units that process input data. Each neuron receives input, applies a weight, and passes the output through an activation function.
2. Layers:

– Input Layer: Accepts the initial data for processing.
– Hidden Layers: Perform computations and extract features. A network can have multiple hidden layers (deep learning).
– Output Layer: Produces the final output or prediction.
3. Weights and Biases: Parameters that adjust the strength of connections between neurons.
4. Activation Function: Determines if a neuron should activate and pass its signal forward (e.g., ReLU, Sigmoid, or Tanh).

How It Works:

1. Forward Propagation: Input data passes through the network layer by layer, and the output is computed at each layer.
2. Loss Calculation: The network’s prediction is compared to the actual result using a loss function.
3. Backpropagation: Errors are propagated backward to adjust weights and biases, improving accuracy over time.
4. Learning: The process of optimizing weights using algorithms like Gradient Descent.

Applications:

• Image and speech recognition
• Natural Language Processing (NLP)
• Autonomous vehicles
• Medical diagnosis
• Financial predictions

Neural networks are the foundation of Deep Learning, a subset of AI that excels in handling large datasets and solving intricate tasks.
