An introduction to neural networks covers the foundational concepts of artificial intelligence inspired by the human brain. Neural networks consist of interconnected nodes, or neurons, organized in layers that process and learn from data. They are designed to recognize patterns, make predictions, and solve complex problems by adjusting weights through training. This introduction explains their structure, learning mechanisms, and applications in fields such as image recognition, natural language processing, and data analysis.

❓ Frequently Asked Questions
What is a neural network?
A computational model inspired by the brain that uses interconnected neurons organized in layers to process data, learn patterns, and make predictions.
How do neurons and layers process information?
A neuron multiplies inputs by weights, adds a bias, and passes the result through an activation function. Layers stack many neurons to transform inputs into more abstract representations.
How does training a neural network work?
Training adjusts the network's weights to reduce prediction errors, typically using data and algorithms like backpropagation with gradient descent.
What are common neural network architectures?
Feedforward networks move data forward; convolutional networks (CNNs) are common for images; recurrent networks (RNNs) handle sequences. Different architectures suit different tasks.
