Neural networks are a fundamental building block of machine learning, inspired by the structure and function of the human brain. They are a series of algorithms that can recognize underlying relationships in a set of data through a process that mimics the way the human brain operates.
Basic Concepts
- Neurons: The basic unit of a neural network, responsible for processing information.
- Layers: Composed of neurons, layers are organized into three types: input, hidden, and output.
- Weights and Biases: Adjusted during the learning process to improve the network's performance.
Types of Neural Networks
- Feedforward Neural Networks: Simplest type, where the data moves in only one direction.
- Convolutional Neural Networks (CNNs): Excellent for image recognition tasks.
- Recurrent Neural Networks (RNNs): Ideal for sequential data like time series or natural language.
Applications
Neural networks have a wide range of applications, including:
- Image and Video Recognition
- Natural Language Processing
- Speech Recognition
- Medical Diagnosis
