What is Neural Network ?
A Layman's Guide to Understanding the Brain-Inspired Technology
Neural Networks are a fascinating branch of Artificial Intelligence (AI) that draw inspiration from the complex structure and functioning of the human brain. In this article, we will embark on a journey to demystify Neural Networks in layman's terms, exploring their concepts and providing learning materials to delve deeper into this captivating field. Let's dive into the world of Neural Networks and discover how they revolutionize AI.
Understanding Neural Networks
Imagine a vast network of interconnected brain cells working together to process information. Neural Networks aim to mimic this intricate network to perform intelligent tasks. Just like the human brain, a Neural Network is composed of interconnected layers of artificial neurons, also known as artificial neural units.
The key elements of a Neural Network are as follows:
Artificial Neurons: These are the building blocks of a Neural Network. Each artificial neuron receives input signals, performs a computation, and produces an output signal. These artificial neurons collectively process information, just like the neurons in our brains.
Weights and Bias: Each connection between artificial neurons in a Neural Network has an associated weight. These weights determine the strength of the connection and influence the information flow through the network. Additionally, each artificial neuron has a bias term that adjusts the output signal.
Activation Function: The activation function defines the output of an artificial neuron based on its input. It introduces non-linearities to the network, enabling it to learn complex patterns and make sophisticated decisions.
Training a Neural Network
To make a Neural Network learn and perform tasks, it undergoes a process called training. Training involves providing the network with a set of labeled examples, allowing it to adjust its internal parameters (weights and biases) to minimize errors and improve its predictions.
During training, the Neural Network learns to recognize patterns and relationships within the data, just like how our brain learns from experiences. It adjusts the weights and biases of its artificial neurons, gradually improving its ability to make accurate predictions or decisions.
Learning Materials to Explore
