He set career bests with a 3.54 ERA and 1.24 WHIP in 185 2/3 innings in 2014, and while it would not be wise to expect him to continue to get better entering his age-29 season, fantasy owners should safely expect an ERA under 4.00 and a WHIP below 1.30 in 2015. The one category where Chen will be well below average is strikeouts. His 17.6 percent strikeout rate was near the bottom of the league and is pretty representative of what he should be expected to do going forward.","seasonId":2015,"date":"Tue Feb 10"},"playerRater30DAY":2.5,"playerRater15DAY":-1,"positionRank":49}

The paper "Efficient Second-Order Gradient Boosting for Conditional Random Fields" listed in machine learning
makes use of Markov chain's mixing rate bound for CRF learning.
I enjoy coding. I always try to write machine learning toolkits that are scalable and efficient.
A light weight library that provides a fault tolerant interface of Allreduce and Broadcast for portable , scalable and reliable distributed machine learning programs. Rabit programs can run on various platforms such as Hadoop, MPI and no installation is needed.
Distributed gradient boosting (tree) library. Featured at its extremely fast speed and scalability, available in python, R and Julia.
The distributed version runs on MPI, SGE and YARN. The toolkit can scale to Terascale problems.
A concise and fast implementation of convnet using mshadow.
This project provides an abstract framework to build new matrix factorization variants simply by defining features.

This is a lecture on gradient boosting and boosted trees I made on Oct. 22, when I am TAing Machine learning in UW.
I am taking the statistical view following the idea of LogitBoost, to present boosted trees algorithm as optimization for training loss and regularization in functional space. This is the model used in the
This is an tutorial about expression template.
This is the trick that enables efficient and simple machine learning codes in C++
