AI02 – Introduction to neurons and activation functions. Part 1/4

Part 1 – Introduction. In the first introductory part, we talked a little bit about some historical developments of artificial intelligence. Particularly, we talked about some competitions between man and machine with examples from chess with Garry Kasparov playing against Deep Blue and the Chinese game of GO in which Lee Sedol playing against an…

AI01 – Adversarial Examples: now you see me, now you don’t

Introduction: How many of us have been both dazzled and confused when we were shown an ingenious optical illusion? If you are anything like me it might initially bring surprise and childish emotions of wonder and almost magic, but in a second and more reflective moment you might then wander how did that happened? Can…
