The George system uses a technique called dimensionality reduction to tease out hidden subclasses, and then train a new neural network with that knowledge of the subclasses. The work, said Re, has great applicability in practical applications such as medical diagnosis, where the classification of disease can be mislead by missing the subclasses.

Where people are really spending time in a valuable way, Re contended, is on the so-called long tail of distributions, the fine details that confound even the large, powerful models.

The article summarizes new trends in software engineering that have been driven by recent advances in artificial intelligence. It packs a lot of interesting ideas and is worth reading for clues about new directions we could be taking.
