+
+## Implementation
+
+- EMR: Electronic medical records
+    - Diagnosis, Image Data, Unstructured text data, Medications, Procedures,
+      Lab tests
+    - Data is challenging to use: high dimensionality, sparse, noisy, irregular,
+      biased
+- IoMT: lots of data, lots of money going in
+- Healthcare technology: Better quality of life, with less money required
