Chapter 1: What is a Neural Network?
The world of artificial intelligence (AI) is rapidly evolving, and one of the most talked-about technologies within it is the neural network. But what exactly is a neural network, and how does it work?
Simply put, a neural network is a type of machine learning algorithm inspired by the structure and function of the human brain. It consists of interconnected nodes, or neurons, organized in layers. These neurons process and transmit information through connections called synapses, similar to how neurons communicate in the human brain.
How Neural Networks Learn:
Neural networks learn by processing large amounts of data and identifying patterns. They use a process called «training,» where they are fed data and adjust the strength of their connections (synapses) to improve their ability to predict or classify new data.
Key Concepts:
— Input Layer: The first layer receives the raw data, such as images, text, or numerical data.
— Hidden Layers: These layers process and transform the data through a series of calculations.
— Output Layer: The final layer produces the output, such as a prediction, classification, or a generated text.
— Weights: Each connection between neurons has a weight, which represents the strength of the connection.
— Activation Function: Each neuron applies an activation function to determine its output based on the weighted sum of inputs.
