Sometimes the biggest improvement in an AI system comes not from a better algorithm, but from better data.
NeoRx v1 used seven biomedical databases to build disease knowledge graphs. It worked well on cancer and metabolic diseases. It completely failed on infectious diseases — Grade F for both malaria and Ebola, Grade C for HIV.
NeoRx v2 added one database:
