Hello
Here is the latest Caml Weekly News, for the week of April 05 to 12, 2011.

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).

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
