# A Brief Look at Mixture Discriminant Analysis

Lately, I have been working with finite mixture models for my postdoctoral work on data-driven automated gating. Given that I had barely scratched the surface with mixture models in the classroom, I am becoming increasingly comfortable with them. With this in mind, I wanted to explore their application to classification because there are times when a single class is clearly made up of multiple subclasses that are not necessarily adjacent.

# High-Dimensional Microarray Data Sets in R for Machine Learning

Much of my research in machine learning is aimed at small-sample, high-dimensional bioinformatics data sets. For instance, here is a paper of mine on the topic.

# How to Download Kaggle Data with Python and requests.py

Recently I started playing with Kaggle. I quickly became frustrated that in order to download their data I had to use their website. I prefer instead the option to download the data programmatically. After some Googling, the best recommendation I found was to use lynx. My friend Anthony recommended that alternatively I should write a Python script.

# Setting Up the Development Version of R

My coworkers at Fred Hutchinson regularly use the development version of R (i.e., R-devel) and have urged me to do the same. This post details how I have set up the development version of R on our Linux server, which I use remotely because it is much faster than my Mac.

# Steve Jobs' 2005 Stanford Commencement Address

And although there are numerous quotes that I could list, I think my favorites are closely related to a few words of wisdom that my grandmother told me when I was younger.
