- 5. Difference Between MLand Deep Learning • ML – the concept existed in the 70s and 80s with the old school statistical analysis, study of probabilities, regressions, • Concept of deep learning existed in the early 80s, only the invent of parallel computing and cheap processing power with commodity hardware has expedited the use of deep learning algorithms • Primary difference is the feedback mechanism involved with the Deep Learning algorithms that is absent in ML algorithms (it works in multiple passes)

Results • 1st Pass –90features and 8 target variables –Smaller size target buckets were extremely accurate –Larger size target buckets had sprinkled outliers all over the place, unwarranted breaks and overlaps • 2nd Pass –Proximity, feature size in consecutive offsets and location as features and same 8 target variables –Outliers were largely gone, overlaps were completely eliminated • In terms of accuracy at the level of single offset the prediction error was only 12%
