Day 12: 3D visualization of scalp electrode sites can be done with Perl

Seeing is believing. A better presentation can more easily persuade people with your story. I, working as an EEG (electroencephalography) researcher, sometimes need to consider the location of its origin, referring to the electrode positions used while recording the data. This is because the scalp distribution of the recorded EEG potential (amplitude) can be affected by how the electrodes align with each other. Here I need to better visualize 3D locations of electrode positions.

Let’s try visualization of those electrode positions using Perl, in 3D manner, where you can change the camera position to watch them from your favorite angle/direction!

Day 5: Using k-means clustering as a ... crayon?

The mtcars dataset is 50 years old. This is the 21st Century, so let's look at Electric Vehicles with k-means clustering. The results are shocking!

Punning without a license? Guilty as charged!
