and the travelling salesman is…

Here is another attempt at using StippleGen on… Alan Turing‘s picture. My reason for attempting a travelling salesman rendering of this well-known picture towards creating a logo for PCI Comput Stats, the peer community project I am working on this summer. With the help of the originators of PCI Evol Biol.

exciting week[s]

The past week was quite exciting, despite the heat wave that hit Paris and kept me from sleeping and running! First, I made a two-day visit to Jean-Michel Marin in Montpellier, where we discussed the potential Peer Community In Computational Statistics (PCI Comput Stats) with the people behind PCI Evol Biol at INRA, Hopefully taking shape in the coming months! And went one evening through a few vineyards in Saint Christol with Jean-Michel and Arnaud. Including a long chat with the owner of Domaine Coste Moynier. [Whose domain includes the above parcel with views of Pic Saint-Loup.] And last but not least! some work planning about approximate MCMC.

On top of this, we submitted our paper on ABC with Wasserstein distances [to be arXived in an extended version in the coming weeks], our revised paper on ABC consistency thanks to highly constructive and comments from the editorial board, which induced a much improved version in my opinion, and we received a very positive return from JCGS for our paper on weak priors for mixtures! Next week should be exciting as well, with BNP 11 taking place in downtown Paris, at École Normale!!!

crowd-based peer review

In clear connection with my earlier post on Peer Community In… and my visit this week to Montpellier towards starting a Peer Community In Computational Statistics, I read a tribune in Nature (1 June, p.9) by the editor of Synlett, Benjamin List, describing an experiment conducted by this journal in chemical synthesis. The approach was to post (volunteered) submitted papers on a platform accessible to a list of 100 reviewers, nominated by the editorial board, who could anonymously comment on the papers and read others’ equally anonymous comments. With a 72 hours deadline! According to Benjamin List (and based on  a large dataset of … 10 papers!), the outcome of the experiment is one of better quality return than with traditional reviewing policies. While Peer Community In… does not work exactly this way, and does not aim at operating as a journal, it is exciting and encouraging to see such experiments unfold!

peer community in evolutionary biology

Posted in Statistics with tags , , , , , , , on May 18, 2017 by xi'an

My friends (and co-authors) from Montpellier pointed out the existence of PCI Evolutionary Biology, which is a preprint and postprint validation forum [so far only] in the field of Evolutionary Biology. Authors of a preprint or of a published paper request a recommendation from the forum. If someone from the board finds the paper of interest, this person initiates a quick refereeing process with one or two referees and returns a review to the authors, with possible requests for modification, and if the lead reviewer is happy with the new version, the link to the paper and the reviews are published on PCI Evol Biol, which thus gives a stamp of validation to the contents in the paper. The paper can then be submitted for publication in any journal, as can be seen from the papers in the list.

This sounds like a great initiative and since PCI is calling for little brothers and sisters to PCI Evol Biol, I think we should try to build its equivalent in Statistics or maybe just Computational Statistics.
