Ex Machina

A movie review with some fun discussion of the Turing test.

Spoiler Alert!

The thing I like the most about Ex Machina is that one of the protagonists not only gives us a proper definition of the Turing test, but he also describes a delicious modification of the Turing test that took me a second to savor fully. The plot also twists quite nicely in the end, though we kind of see it coming.

Movies about machines that replicate human thoughts and emotions pop up periodically. In most of these movies the machines win. Ex Machina is one of the better ones of this genre. Particularly satisfying is that the techno babble in the script touches on some advanced topics in machine intelligence.

To start with, there is a good definition of the Turing test. People make a lot of fuss about the Turing test and take it quite seriously and literally. The Turing test, to me, is basically is an admission that, when people…

The magic of memoization

Project Euler problem #15 (This may be a spoiler BTW) can be solved via recursion, but because the tree is so wide it quickly blows up. More irritatingly, much like computing the Fibonacci sequence recursively, we keep doing the same computation over and over again. I knew how to solve this using imperative programming and …
