Neural Network
A neural network is a computing model inspired by biological neurons: layers of connected nodes that process inputs with learned weights and nonlinear functions. They are the building blocks of modern deep learning.
In Simple Terms
Think of it as a team of filters: each layer passes information to the next, refining the signal until the network produces an answer.
Detailed Explanation
Each layer transforms its input; early layers often capture low-level features (edges, words), and deeper layers capture more abstract patterns. Training adjusts the weights (and sometimes architecture) via backpropagation and gradient descent. Neural networks scale with data and compute and power most of today's AI applications. Architectures vary: feedforward networks, convolutional networks (vision), and transformers (language and beyond). Understanding the basics helps with model choice, debugging, and communicating with technical teams.

Bias in AI is systematic error or unfairness in how a model treats individuals or groups, often reflecting skewed data or flawed design. It can worsen existing inequalities if left unchecked.
