Deep Learning – What is it and why does it matter?

Deep Learning – what on earth does that mean?

Title ImageHave you ever wondered just what this phrase Deep Learning is referring to and why it matters? If so then this post is for you!

In my last post, I demystified a variety of buzzwords, and explained that Deep Learning is a subset of Machine Learning. This post explores the world of deep learning for non-mathematicians (just like myself). In doing so it:

  • Touches on convolutional neural networks;
  • Explains the impact Deep Learning is having on Cognitive Computing;
  • Outlines a few examples of Cognitive Computing (Deep Learning) in action.

Starting with Artificial Neural Networks

To understand Deep Learning, you must first understand a little about Artificial Neural Networks. Don’t worry – as I am not a data scientists I will not try to describe the mathematics behind it all. That means no talk beyond this sentence of weighting, activation functions and more.

Deep Learning normally revolves around the use of Artificial Neural Networks with more than 1 hidden layers. More on what a hidden layer is shortly.  The theory is that the more hidden layers you have the more you can isolate specific regions of data to classify things.

Artificial Intelligence (AI) – Demystifying the latest buzzword

Artificial Intelligence (AI) – Demystifying the latest buzzword

Everywhere you turn today someone is talking about Artificial Intelligence (AI). It appears to have taken over as the largest buzzword since Big Data.

Progressive organizations are actively seeking ways to apply AI. They want to use it to advance their businesses and build new experiences for those they interact with internally and externally.

Alas there is great confusion as to what AI means. That just gets worse when people mix that up with terms such as Machine Learning and Deep Learning. If you ask several different people their view on what is AI, or Machine Learning, you will get several different answers.

AI ElephantIt is the age-old problem of describing an elephant dependent on which side of it you touch while blindfolded.

AI is not a new topic. People have been pursuing AI since the 1940s. Machine Learning, which has developed from the field of Artificial Intelligence, has been around since at least the 1980s and Deep Learning, which is a subset of Machine Learning, has been rapidly gaining in popularity over the past 10 years. This post explores all these topics setting the scene for some upcoming posts.
