Neural Networks are an important part of Artificial Intelligence (AI) and Machine Learning (ML). They are inspired by the way the human brain processes information and are designed to learn patterns from data.
What is a Neural Network?
A Neural Network is a computational model made up of interconnected neurons arranged in layers:
Input Layer – Receives data
Hidden Layers – Process and learn patterns
Output Layer – Produces the result
The network learns by adjusting weights and biases during training.
How Does It Work?
The basic process is:
Input → Processing → Prediction → Error Calculation → Weight Update
Techniques such as backpropagation and optimization algorithms help the network improve its predictions.
Types of Neural Networks
Some common types include:
Feedforward Neural Networks – Basic prediction and classification
CNN – Image and computer vision applications
RNN – Sequential and time-series data
LSTM – Long-term sequence processing
Transformers – Modern NLP and Generative AI applications
