I am a software developer. I am particularly fond of the areas:

  • artificial intelligence, computer vision & machine learning
  • high end graphics & image processing
  • games

As this profile is now posted across multiple sites:

I am a member of the Church of Jesus Christ of Latter-Day Saints, also known as a Mormon.
I am also a mathematician.
I quite like interesting games and enjoy playing them with those of my many wonderful children who are old enough. We will often edit what we might find to be sleazy in a game without altering the game play, which quite widens the range of games we can play while staying within what we consider to be gospel standards.

comment What is the proper way to do vector based linear regression in R
There is strong physical cause to believe the real relationship in my case is y = Ax + b plus some noise. The matrix A is important as it is related to a rotation in the system. I really want the matrix A. It is crucial information for my purpose.

comment Control the size of points in an R scatterplot?
For many small points, using alpha (transparency) can make a scatter plot much more informative than just using fewer points to plot it.
