@becausealice2 not really a curriculum, per se, but this lists some good higher level perspective on being a data scientist to keep in mind while doing a more structured approach to learning data science :point_up: December 9, 2016 6:22 AM

McKinsey's 2016 Analytics Study Defines The Future of Machine Learning

Main points made:

  • Location-based services and U.S. retail are showing the greatest progress capturing value from data and analytics.
  • Machine learning’s greatest potential across industries includes improving forecasting and predictive analytics.
  • Machine learning’s potential to deliver real-time optimization across industries is just starting to evolve and will quickly accelerate in the next three years.
  • Enabling autonomous vehicles and personalizing advertising are two of the highest opportunity use cases for machine learning today.
  • Designing an appropriate organizational structure to support data and analytics activities (45%), Ensuring senior management involvement (42%), and designing effective data architecture and technology infrastructure (36%) are the three most significant challenges to attaining data and analytics objectives.
  • U.S. retailer supply chain operations who have adopted data and analytics have seen up to a 19% increase in operating margin over the last five years.
  • Design-to-value, supply chain management and after-sales support are three areas where analytics are making a financial contribution in manufacturing.

@becausealice2 I started from scratch with no formal math. I craft my own learning path. The Moocs are all good. But since my own 'graduation' project is highly advanced I now started a dual track. I search for the knowledge I need and start using it. So I have my own research project that in the end must be proof of skills. I document my steps etc. this very practical hands on is still missing largely. It makes it harder to get a sense of workflow. Math can be an issue. However I find it less difficult when it is directly related to reality. So the stats and math concept I do on the fly. The first thing I noticed when exploring a freelance site was that the issues where not like the curriculum. So I got stuck and almost in despair. It is why I changed my approach. Hacking into DS. No easy fix and unpredictable difficulties create more confidence and knowledge. Even though at humble beginnings it will encompass a lot. Data cleaning, encoding, survey, nlp, ml and visualization of narrative etc. most courses take quite some time and combining them make you a full time student. As data cleaning is the most important thing in the process. I would suggest anyone who starts focus on that. It makes you I guess fast employable. Machine learning is as good as one knows where to look and where to find the data to combine.

@erictleung interesting... Forbes made a similar forecast:

Now just have to wait if it is not another kind of USA elections thing and they get it all wrong again... :(

@mesmoiron wow! And @becausealice2 is being honest: She never said that to me when advising her :(

@evaristoc in all fairness, I have a better idea now of what I don't know than I did back when you were the only one advising me, so I know when thanks and praise are appropriate. but thank you for all your help, I can guarantee I wouldn't have made it this far without your help ;)
