During a discussion with my wife about the Batman vs. Superman film from earlier this year, the question came up as to whether the box office drop from the opening to the 2nd weekend was normal, or whether it dropped more than it should have due to bad word of ...
During a recent personal project I was working with Deep Learning models, and in particular trying to fine tune a CNN (AlexNet) in Caffe. At first I was getting some pretty strange, and frustrating, learning curves.
It turned out that my error was that I was that I was running ...
This is a brief summary of my first experience with a Kaggle competition. I entered for the learning experience, and because I wanted to play around with a real problem in machine learning.

It feels like we are in a a crisis of science education and understanding. From overreaction and scare stories about Ebola, to the spread of measles due to vaccination myths, it has become far too easy for the general public to become influenced by scare stories and fear-mongering.

I came across an article recently about problems that customers have been having with a popular and fast-growing tech startup. Mostly these seem to be because of a lack of formalized customer service processes, rather than any massive flaw in the underlying product, team or business model.
