Each of us has a different answer for Òwhy is machine learning so hard.Ó And how long you have been working on ML will drastically influence your answer.
I'll share what I learned over the past 20 years, implementing everything from scratch for 1 model in web search ranking, 100s of models for Sybil and 1000s of models for TFX. YouÕll see why I'm convinced that data and software engineering are critical for successful data science - more so than models. Regardless of your experience, IÕll share some tips that will help you overcome the hard parts of machine learning.
