Welcome to the basics of Neural Networks tutorial! If you're new to AI and machine learning, this guide will help you understand the foundational concepts of neural networks.
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. In other words, it learns from examples to make better decisions in the future.
Components of a Neural Network
- Neurons: The basic building blocks of a neural network.
- Layers: Different layers of neurons perform different functions.
- Input Layer: Receives input data.
- Hidden Layers: Process the input data and transform it.
- Output Layer: Produces the final output.
- Weights and Biases: Adjusted during the learning process to minimize the error.
Types of Neural Networks
- Feedforward Neural Networks: The simplest type of neural network.
- Convolutional Neural Networks (CNNs): Widely used in image recognition.
- Recurrent Neural Networks (RNNs): Good at processing sequential data.
- Autoencoders: Used for unsupervised learning.
Learning Process
The learning process involves adjusting the weights and biases of the neural network based on the input data. This process is called backpropagation.
Example
Imagine you are trying to classify images of cats and dogs. You would train a neural network using a dataset of cat and dog images, and the network would learn to distinguish between the two.
