Neural networks are a fundamental building block of modern artificial intelligence. Understanding their structure is crucial for anyone interested in machine learning. This tutorial will provide an overview of the key components of a neural network.
Overview
A neural network is composed of interconnected layers of nodes, or neurons. Each neuron is connected to multiple other neurons in the previous and next layers. The connections between neurons are weighted, and these weights are adjusted during the training process to improve the network's performance.
Key Components
- Input Layer: The first layer of the neural network, which receives input data.
- Hidden Layers: Intermediate layers that perform computations and transform the input data.
- Output Layer: The final layer of the neural network, which produces the output.
Learning Process
The learning process involves adjusting the weights of the connections between neurons based on the input data. This is done using a technique called backpropagation.
Examples
Here are some examples of neural network structures:
- Simple Neural Network: A single-layer network with an input layer, hidden layer, and output layer.
- Convolutional Neural Network (CNN): A deep learning network used for image recognition and other tasks involving visual data.
- Recurrent Neural Network (RNN): A network that processes sequences of data, such as time series or text.
