Hello all, I have completed an application for Google Summer of Code for the implementation of the PCA algorithm in Mahout. My research is directly related to the use of PCA, so I am very familiar with that algorithm. However, since I work in the area of pattern recognition and machine learning, I am also familiar with the other algorithms listed on your site. Since there was not a ranking of desired algorithms, I chose PCA, but if there is a more immediate need for a different algorithm, I can most likely help with that instead / as well. Please let me know if you need any further information.
Thanks, Josh Harguess
