How to Improve Machine Learning Algorithms? Lessons from Andrew Ng, part 2

Welcome to the second chapter of ML lessons from Ng's experience. This will be a short one and we will only be talking about Human Level Performance & Avoidable Bias. If you did not read the first chapter, here's the link. Oh and one more thing, this series is entirely based on a recent course by Andrew Ng on Coursera. In the last few years, a lot more machine learning teams have been talking about comparing the machine learning systems to human level performance.
