Validation of Machine Learning based diagnostic devices and biomarkers

The recent application of machine learning on biomedical images and signals and biomarkers in general has opened up avenues to explore and develop non-invasive diagnostic devices. The development of these classifier algorithms are mostly taken up in an early phase proof-of-concept study (POC). A proper validation of these devices must still be carried out in a pivotal trial based on a completely independent (of POC) data set before the device can be registered for market. In this talk, we explore statistical aspects of trial design for these pivotal trials such as primary endpoint selection, sample size and operating characteristics and adaptive strategies. In particular, we look at seamless and Bayesian strategies in order to minimize the logistical burden of such pivotal trials.
