Neural networks are a fundamental concept in artificial intelligence and machine learning. They mimic the structure and function of the human brain, enabling machines to learn from data and make predictions or decisions.
What is a Neural Network?
A neural network is a series of algorithms that attempt to recognize underlying relationships in a set of data through a process that mimics the way the human brain operates. Neural networks are made up of layers of interconnected nodes, or "neurons," which process information.
Layers of a Neural Network
- Input Layer: This is where the data enters the neural network.
- Hidden Layers: These layers perform computations using weights and biases.
- Output Layer: This layer produces the final output of the neural network.
How Neural Networks Work
Neural networks work by adjusting the weights and biases of the neurons based on the input data. This process is known as "training." During training, the neural network learns to recognize patterns and make predictions based on the data it has been given.
Types of Neural Networks
- Feedforward Neural Networks: This is the most basic type of neural network.
- Convolutional Neural Networks (CNNs): These networks are commonly used for image recognition.
- Recurrent Neural Networks (RNNs): These networks are used for sequence prediction tasks, such as language translation.
Applications of Neural Networks
Neural networks have a wide range of applications, including:
- Image recognition
- Natural language processing
- Speech recognition
- Medical diagnosis
- Financial trading
