Neural network architecture refers to the structural design of artificial neural networks used in machine learning and artificial intelligence. These systems are inspired by the way the human brain processes information through interconnected neurons. In computing, neural networks consist of layers of mathematical units that process data and learn patterns from it.
The primary goal of neural network architecture is to enable computers to analyze complex data, recognize patterns, and make predictions. This capability supports applications such as natural language processing, image recognition, predictive analytics, and recommendation systems .
A neural network typically includes three major components that work together to process and interpret data efficiently.
Key Components of Neural Networks
-
Input Layer
- Receives raw data such as text, numbers, or images
