Neural networks are at the heart of modern machine learning and artificial intelligence. These computational models mimic the complex functions of the human brain, enabling tasks such as pattern recognition, decision making, and more. In this article, we’ll explore the basics of neural networks, their working, and their applications.

What are Neural Networks?

At its core, a neural network consists of interconnected nodes or neurons. These neurons process and learn from data, extracting identifying features without pre-programmed understanding. Unlike traditional algorithms, neural networks adapt and improve their performance over time.

How do Neural Networks Work?

1. Neurons and Connections : Neurons receive inputs, which are governed by thresholds and activation functions.Connections involve weights and biases that regulate information transfer between neurons.

2. Learning Process : Neural networks learn through iterative refinement.The process involves input computation, output generation, and adjusting weights and biases.

3. Three Stages of Learning
Input Computation: The network processes input data.
Output Generation: The network produces an output based on the computed data.
Iterative Refinement: The network adjusts weights and biases to enhance its proficiency.

How do Neural Networks Work?

1.Image Recognition: CNNs excel at identifying objects in images.Used in self-driving cars, medical imaging, and security systems.

Natural Language Processing (NLP): RNNs process sequential data, making them ideal for NLP tasks.Used in chatbots, language translation, and sentiment analysis.

3.Recommendation Systems: Neural networks learn user preferences and recommend personalized content.Used by platforms like Netflix and Amazon.
