How to Reduce Bias in Machine Learning

The way algorithms are outperforming humans is that they're averaging over the noise. But of course, if we don't have much data, then they basically can't average over the noise and the more noise there is, the more data they need. And you can improve accuracy not only by reducing bias, but you actually improve accuracy even when you leave bias the same by reducing noise. That's the key to Gauss's rule about how to measure error and accuracy.
