Inside a Neural Network – Computerphile

Let’s start talking about convolutional neural networks again A few people have been asking what does the convolutional layers look like So you know, what transformations are happening on these input images, that mean we can do something interesting in terms of machine learning. So, what I’ve done is that

Almost All Web Encryption Works Like This (SP Networks) – Computerphile

Let’s talk a little bit about encryption and specifically kind of modern encryption and how it works Now before we jump straight into something like the advanced encryption standard. I wanted to talk about SP networks or Substitution-Permutation networks because they are the basis for a lot of modern cryptography — not

Neural Network that Changes Everything – Computerphile

This is kind-of a follow up to Brais’ videos on deep learning So deep learning is kind of a big thing at the moment and there’s some disagreement between research over whether this is gonna be – the, this is *it* This is the big thing that’s gonna change everything

The Grid, CERN’s Global Supercomputer – Computerphile

We opted [for] a distributed structure which was in essence a precursor of cloud computing that we all know today And we called it. The [grid] we’ve agreed you are able to share resources computing resources storage resources, so you are able to share a Lot of computers connected to
