Convolutional Neural Network Created 1989 2009 2015 1.5 Million classified images with 1,000 object categories released to public Microsoft Research surpasses human recognition performance 26 years 6 years

SLIDE 15

MEDICAL DATA ARE A PUBLIC GOOD AND SHOULD BE OPEN SOURCED TO BENEFIT ALL

SLIDE 16

SLIDE 17

Not divided or consumed and easily replicated “Ownership” of data is an imprecise concept

Rights to control access
Rights to share of profit

Value of data and information is relative

Exclusive access to data may give relative advantage
Advantage negated when others have access to the same data

DATA are not Traditional Form of Property

SLIDE 18

SLIDE 19

but… Medical Data are PEOPLE

SLIDE 20

Our position: Once clinical data have been used to provide care, the primary purpose for acquiring the data is fulfilled. For secondary use: Clinical data should be treated as a form of public good used for the benefit of all thorough open source research and education NOT for sale or exclusive partner access

SLIDE 29

Responsible ethically sound processes exist to make medical data available Publishing without sharing data is just marketing NOT science Alternative approaches to solve data availability are complimentary Open source medical data and benchmark competitions will accelerate innovation
