Machine Learning , some thoughts

Gerard I suggest you prepare a concept proposal for your standards organisation to submit to CEN or ISO.  My co-director of GeHCo chairs the ISO WG on all data matters, have you had a look at their current worklist?  ICO TC2215  or CEN TC251?  Anyone who identifies a standards gap is able to take action through the relevant organisations.

Any one automobile or airplane or house is built using many, many standards.


The models/standards I mentioned deal with a particular aspect of data to be stored, retrieved, processed and exchanged.

Data that is generated in and by a patient in a context,

observed by a person in a context

Data that is documented using a structural model,

using codings systems based on models/standards,

etc. etc.


All are important, none is king or the centre of the world.




Your joke deals with the situation where there are competing standards.

In my case I mention standards that do not compete, do not overlap.

GF said: We need standards on how to describe the health data and their epistemology/context, modeling patterns and rules on how to use coding systems and deal with ‘negation’, just to mention a few other things needed to define data inside EHR systems in such a way that data can exchanged.


Dear Gerard, you know the joke?


A: We have 14 standards how to be interoperable in healthcare IT

B: What? I go and create a new standard which replaces all these standards.

A: We have 15 standards how to be interoperable in healthcare IT


The lesson is: We are all to small to be the center of the universe. We can all be a part of it, nothing more.
