I can provide you with:
- a Matlab implementation of Extra-Trees (Geurts et al., 2003-2006)
- a Matlab implementation of the Fitted-Q Iteration algorithm (Ernst et al., 2005) using Extra-Trees
- a Matlab implementation of the CGRL algorithm
- a Matlab implementation of the MFMC estimator
- a Matlab implementation of the BOP algorithm
If you are interested by one of these implementations, please send me an email!
