Finding the origin of noise transients in LIGO data with machine learning, December 2018
We present two machine learning methods, based on random forest and genetic programming algorithms, that can be used to determine the origin of non-astrophysical transients in the LIGO detectors. While the data sets described in this paper are specific to LIGO, … the code bases and means by which they were applied … are completely portable to any number of instruments in which noise is believed to be generated through mechanical couplings.

Audio Network, February 28, 2017
In How music helps us learn Kai Staats shares how the musical score is an integral part of horror, drama, fantasy and sci-fi. We anticipate that the instruments will amplify our emotions, carry our mood from scene to scene. Yet, documentaries are often devoid of the careful application of score. If we apply the same techniques, the same instrumentation, we not only keep the audience engaged but help the viewer retain the information given.

Marco Cavaglia, Professor Physics at the University of Mississippi and Assistant Spokesperson for the LIGO Scientific Collaboration presents “LIGO detector characterization with Genetic Programming” in which we apply GP to categorization of LIGO noise and show that it can effectively be used to characterize the detector non-astrophysical noise both in low latency and offline searches.
Genetic Programming Applied to RFI Mitigation in Radio Astronomy, December 2016
The MSc thesis for Kai Staats, University of Cape Town, South Africa. At the time of this research, the application of machine learning to radio astronomy was relatively new. Genetic Programming had never been applied, and as such, was a novel approach to this challenging arena. Foundational to this body of research, the application Karoo GP was developed and tasked with the classification of signal verus radio frequency interference (RFI). The training data was derived from the output of an observation run of the KAT-7 radio telescope array built by the South African Square Kilometre Array (SKA-SA).

Genetically optimized weather predictions built upon the Southern African Large Telescope (SALT) weather monitoring database. This remarkably simple approach developed principally by head astronomer Stephen Potter derives a functional weather predictor in order to prepare dome environment conditions for night time operations or plan, prioritize and update weather dependent observing queues.

The Committee on Human Spaceflight (NASA Authorization Act of 2010) requires that the National Academies perform a human spaceflight study [to] review “the goals, core capabilities, and direction of human space flight” … this language reflects concerns that—without an accepted and independent basis for the establishment of long term goals—political cycles and other factors would continue to drive instability in the human spaceflight program.

Humanity & Technology, 2004, 2010-12
Humanity & Technology is a column I wrote for MacNewsWorld (’04) and Northern Colorado Business Report (’10-12). Not a comparison of the speed of the latest wifi networks, but an introspective look at the effect of deeper integration of technology into the human experience, bringing to focus how our interaction with technology affects our relationship with each other, how it shapes the social evolution of our species.
The Stars’ Embrace, 2009
In The Stars’ Embrace, Kai Staats offers nineteen stories written over twenty years. His science fiction takes the reader from the ruthless rule of a near-future government, whose citizens are held captive by mind altering medication, to a distant planet where the remaining astronauts of a failed mission have lost all hope.
