Ranyard Medal

The Ranyard Medal is awarded in recognition of the most outstanding contribution to the philosophy, theory or practice of business analytics published in the Journal of Business Analytics within the relevant two year period.

This is a new award and reflects the success this journal has achieved in the three years since its launch. The Ranyard Medal will be awarded biennially. This inaugural award relates to work published in the 2018 – 2019 editions [Volumes 1-2].

This award is named in honour of John Ranyard, who made a significant contribution to the field of Business Analytics.

Dr John Ranyard had a distinguished career as a practitioner within OR, establishing himself as a leader in building relationships between academics and industry, commerce, and the public sector.

He has been awarded several honours over his distinguished career, including the Companionship of the UK Operational Research Society 2005.

This year’s Ranyard Medal is presented to Jonas Wanner, Lukas-Valentin Herm, Kai Heinrich and Christian Janiesch, for their Paper entitled “A social evaluation of the perceived goodness of explainability in machine learning”

Machine learning and Artificial Intelligence are now seen as the go-to solution to almost every problem. But there remains a key question as to whether potential users trust the advice offered by such methods, accepting its direction or modifying it to suit their understanding of the problem. Many of these methods offer solutions – recommendations or forecasts – that are black box in essence. This paper explores the concept of explainable machine learning, which they break into two dimensions: global, focused on the algorithm’s features, and local explainability concerned with the specifics of its performance. The authors have applied several machine learning algorithms to  various contrasting problems and evaluated the users’ experience of these models through a survey. Among others, they found that the perceived explainability depends on the familiarity with the problem type and interaction of the modellers with the users. The findings of the research we see as very helpful for  modellers in creating models that are more useful  to practitioners, thereby achieving a more significant impact with machine learning methods better integrated with user needs.
