Hello, Here is the latest Caml Weekly News, for the week of April 05 to 12, 2011.
1) mcmc-ocaml: A Library for Markov-Chain Monte Carlo Computations in OCaml 2) OCaml/Xen google summer of code 3) Other Caml News ======================================================================== 1) mcmc-ocaml: A Library for Markov-Chain Monte Carlo Computations in OCaml Archive: <https://sympa-roc.inria.fr/wws/arc/caml-list/2011-04/msg00028.html> ------------------------------------------------------------------------ ** Will M Farr announced: I'd like to announce mcmc-ocaml, a library for Markov-chain Monte Carlo computations in OCaml. You can obtain the library from github at <https://github.com/farr/mcmc-ocaml> It is released under the GPL, version 3.0. For more information on MCMC, see <http://en.wikipedia.org/wiki/Markov_chain_Monte_Carlo> . Some highlights of the mcmc-ocaml library: * mcmc-ocaml provides code to perform MCMC analysis in arbitrary parameter spaces. Parameter values need not be numerical, but can instead be any OCaml value: algebraic data types, classes, etc. * mcmc-ocaml provides useful higher-order functions to combine multiple jump proposals with arbitrary weights into a single proposal for Metropolis-Hastings sampling, making it easy to have many special jump proposals tuned to your specific parameter space structure. * mcmc-ocaml provides code to read and write MCMC samples from/to files; this can be combined with the library of statistical functions or user-written code to perform post-processing of MCMC output either in a stand-alone program or from the REPL. * mcmc-ocaml provides many utility functions for performing model selection via Reversible-Jump MCMC, either between two models or among a larger set of models. This includes an implementation of the method described in <http://arxiv.org/abs/1104.0984> for facilitating inter-model jumps by interpolating posteriors using single model parameter samples. * mcmc-ocaml provides several different algorithms for computing the Bayesian evidence for a model using MCMC samples from its posterior distribution, including the "direct integration" algorithms described in <http://arxiv.org/abs/0911.1777> . * mcmc-ocaml comes with complete ocamldoc documentation for its functions and types. mcmc-ocaml is extensively tested, and has been used to constrain the mass distribution of stellar-mass black holes in our galaxy (<http://arxiv.org/abs/1011.1459> ---including the 10-way RJMCMC comparisons among the models in that paper), among other research projects. Please direct bug reports, feature requests, and comments to this address (w-farr AT northwestern.edu). ======================================================================== 2) OCaml/Xen google summer of code Archive: <https://sympa-roc.inria.fr/wws/arc/caml-list/2011-04/msg00036.html> ------------------------------------------------------------------------ ** Anil Madhavapeddy announced: Xen.org was accepted to the Google Summer of Code 2011, and I snuck in an OCaml-related project [1]. I haven't received any good applications for this, so if you are interested and eligible, I would encourage you to apply before the deadline tomorrow. Please get in touch with me asap by email if you do plan to put a proposal in. The SSL idea is just a template; pretty much anything interesting (especially profiling-related) to running OCaml "stub domains" on Xen would be relevant. cheers Anil [1] <http://wiki.xensource.com/xenwiki/GSoC_2011_ideas> ======================================================================== 3) Other Caml News ------------------------------------------------------------------------ ** From the ocamlcore planet blog: Thanks to Alp Mestan, we now include in the Caml Weekly News the links to the recent posts from the ocamlcore planet blog at <http://planet.ocamlcore.org/>.
