Episode 18: AI - What is a Model?

May 29, 2020, 04:27 PM

In this episode Andrew and Danny demystify AI and machine learning by explaining what a model is, what one does and how models differ from programming.

A machine learning model is a mathematical function.  There, that was easy!

In order for Machine Learning AI models to operate on something you have to reduce it to numbers.  Fortunately, everything in the world of computers is a number underneath.  A photo is a collection of numbers.  A video is a collection of numbers.  You feed these into your model and what you get back is....more numbers.

The maths that makes this happen is quite mind-bending.  The good news - you don't need to know it!  The AI tools we now have available do the heavy lifting for us and let us build and use models without needing a PhD in mathematics.
