Responsible and Regulatory Conform Machine Learning for Medicine: A Survey of Challenges and Solutions
Machine learning is expected to fuel significant improvements in medical
care. To ensure that fundamental principles such as beneficence, respect for
human autonomy, prevention of harm, justice, privacy, and transparency are
respected, medical machine learning systems must be developed responsibly. Many
high-level declarations of ethical principles have been put forth for this
purpose, but there is a severe lack of technical guidelines explicating the
practical consequences for medical machine learning. Similarly, there is
currently considerable uncertainty regarding the exact regulatory requirements
placed upon medical machine learning systems. This survey provides an overview
of the technical and procedural challenges involved in creating medical machine
learning systems responsibly and in conformity with existing regulations, as
well as possible solutions to address these challenges. First, a brief review
of existing regulations affecting medical machine learning is provided, showing
that properties such as safety, robustness, reliability, privacy, security,
transparency, explainability, and nondiscrimination are all demanded already by
existing law and regulations - albeit, in many cases, to an uncertain degree.
Next, the key technical obstacles to achieving these desirable properties are
discussed, as well as important techniques to overcome these obstacles in the
medical context. We notice that distribution shift, spurious correlations,
model underspecification, uncertainty quantification, and data scarcity
represent severe challenges in the medical context. Promising solution
approaches include the use of large and representative datasets and federated
learning as a means to that end, the careful exploitation of domain knowledge,
the use of inherently transparent models, comprehensive out-of-distribution
model testing and verification, as well as algorithmic impact assessments

On the Road to Addiction: The Facilitative and Preventive Roles of Marketing Cues
This research broadens the focus on the addiction process by examining the role of marketing cues in the âpre-addictionâ phase of the consumption continuum that is broadly conceptualized to include behavior that may or may not result in addiction. If addictive behavior is to occur then dependence on that behavior occurs leading to negative or harmful consequences as consumption increases over time becoming a critical component of the individual\u27s life. Of central interest to this research are the environmental triggers that influence such pre-addiction consumption behaviors with a specific focus on the role marketing cues can play in facilitating and preventing the progression from non-use to addiction. We suggest that marketing cues have the potential to heavily influence the path towards and away from addiction and we identify types of cues that can impact each phase, or multiple phases, of the consumption continuum
