What's this thing?
I use this space to try new things. Hopefully, some of them might be of your interest.
PCA with Missing Values
PCA is a very simple but useful technique to reduce data dimensionality. One of the main reasons to reduce the dimensionality is that it helps finding patters in our data. However, in several of the applications where PCA is useful, we encounter that missing data.
For example, assume we have set of measurements for a group of elements. It is common to have some missing measurements for some of those elements. Maybe it was not possible to make that measurement, or measuring is not under our control, and the measurement wasn't done yet.

I wanted to try out this library, so, here's an equation And here's a set of equations, a little bit more related to my research
The amazing people from the Rubik's cube official website made available a virtual rubik cube to play online. I think it's the same version used by Google on their doodle from May 2014.
As the Rubik's cube geek I am, I wanted to try that on my own website. So, here it is!
You can play with the mouse, or using the keyboard. The keys L, R, U, D, F, B and their corresponding lowercase turn left, right, up, down, front and back, clockwise and counterclockwise repectively. The keys X, Y and Z to turn the cube on the different axes.
