摘要: There is a huge gap between (1) the state of workflow technology on the one hand and the practices in
the many labs working with data driven methods on the other and (2) the awareness of the FAIR principles
and the lack of changes in practices during the last 5 years. The CWFR concept has been defined which is
meant to combine these two intentions, increasing the use of workflow technology and improving FAIR
compliance. In the study described in this paper we indicate how this could be applied to machine learning
which is now used by almost all research disciplines with the well-known effects of a huge lack of repeatability
and reproducibility.
Researchers will only change practices if they can work efficiently and are not loaded with additional
tasks. A comprehensive CWFR framework would be an umbrella for all steps that need to be carried out to
do machine learning on selected data collections and immediately create a comprehensive and FAIR
compliant documentation. The researcher is guided by such a framework and information once entered can
easily be shared and reused. The many iterations normally required in machine learning can be dealt with
efficiently using CWFR methods.
Libraries of components that can be easily orchestrated using FAIR Digital Objects as a common entity to
document all actions and to exchange information between steps without the researcher needing to
understand anything about PIDs and FDO details is probably the way to increase efficiency in repeating
research workflows. As the Galaxy project indicates, the availability of supporting tools will be important to
let researchers use these methods. Other as the Galaxy framework suggests, however, it would be necessary
to include all steps necessary for doing a machine learning task including those that require human interaction
and to document all phases with the help of structured FDOs.
