Tamr Field Engineer Timothy Danford, Ph.D., discusses how Data Variety -- the natural, siloed nature of data as it’s created -- is creating a bottleneck to biomedical data analytics. Rule-based, deterministic data unification approaches are “too brittle” scale to the hundreds or thousands of different data formats, sources and silos within the enterprise. Danford submits, instead, that Tamr’s bottom-up, probabilistic approach with “active learning” is proving successful at unifying heterogeneous data at scale.
