Bureau international des poids et mesures

Today, I am taking part in a meeting in Paris, for an exotic change!, at the Bureau international des poids et mesures (BIPM), which looks after a universal reference for measurements. For instance, here is its definition of the kilogram:

The unit of mass, the kilogram, is the mass of the international prototype of the kilogram kept in air under three bell jars at the BIPM. It is a cylinder made of an alloy for which the mass fraction of platinum is 90 % and the mass fraction of iridium is 10 %.

And the BIPM is thus interested in the uncertainty associated with such measurements. Hence the workshop on measurement uncertainties. Tony O’Hagan will also be giving a talk in a session that opposes frequentist and Bayesian approaches, even though I decided to introduce ABC as it seems to me to be a natural notion for measurement problems (as far as I can tell from my prior on measurement problems).

    Very interesting, I like the part where machine learning is proposed for model selection. Can you recommend any paper where this subject is discussed?
