Backpropagation Explained: A Worked Neural Network Example with House Prices

Leave a Comment / Artificial Intelligence, Featured

Backpropagation can sound like one of the most intimidating parts of artificial intelligence. In practice, the idea is much simpler: a neural network makes a prediction, measures how wrong it was, calculates which weights contributed to that error, and adjusts those weights slightly. This worked example follows that entire process using three house-price predictions and […]

Understanding Artificial Neural Networks – A Conceptual Guide

Leave a Comment / Artificial Intelligence, Featured

Artificial neural networks sit behind many of the AI systems people now use every day. They help models recognise images, interpret speech, detect patterns, make predictions and generate language. The mathematics can become sophisticated, but the basic idea is surprisingly approachable: take numbers in, transform them through layers of learned parameters, and produce an output.

Transformers and Large Language Models: The Brains Behind Modern AI

Leave a Comment / Artificial Intelligence, Featured

Much of today’s generative AI is built on an architecture called the transformer. Transformers changed how machines process language by allowing models to represent relationships between words, tokens and other pieces of information across a sequence. Large language models build on that architecture at enormous scale. Transformers provide the architecture behind many modern large language

How Does AI Learn Today? From Rules to Deep Learning

Leave a Comment / Artificial Intelligence, Featured

Artificial intelligence did not begin with systems that learned from billions of examples. Many early AI systems depended on rules written explicitly by people. Modern AI takes a different approach: instead of describing every decision in advance, we train mathematical models to discover useful patterns from data, feedback and experience. Modern AI learns patterns from
