About the Sleeper's Orgasmatron of Woody Allen and beyond...

It is incredible how fiction is becoming reality. It is like we are being part of a movie. I hope it is a good one, with a nice Holywood happy ending... :)

If you like art films and classics, and you want to find out more about this trend of past fiction becoming reality that is so popular nowadays, then I will recommend to check out Network, a film made in 1973 that was the first fictional featuring of reality shows. You will also find a lot of good dialogues that conform to the present events in USA, in my opinion.

Here an interesting review about the film published on BBC News:

Someone asked what my motivation was for offering to help out their non-profit (which teaches techy things to people who need help getting techy jobs) fine tune their Data Science track, and I've never had such a hard time explaining anything ever.
Also, what would each of you consider necessary basic skills for an entry level DS position?

@becausealice2 Well take my views with a grain of salt. I have never worked as a DS. That said the job is very old and used to be not sexy. I came from mathematical visualization perspective. People do 'analog' DS. That's what I rebellious call it. If you want to make inferences and predictions based on testable hypothesis with quality; then you enter the realm of formal DS. However there's a difference between mom and dad non-profit and large multi nationals. Everything in between as to playing around with excel and drop in a pie chart. DS comes with the task of educating the customer. So what should someone know? Coursera has a course building the data science team. I can recommend it. High end. But for everything else. I recommend creativity, skepticism. Love for scientific inquiry. Know programming.But above all e curious mind that can dig up many questions. Data cleaning because it is never nice. Realistic mindset because without DS interest it is unlikely that the best information already is accumulated. Feature engineering is closely related to that. The ability to listen without dropping buzzwords. Optional putting on those sexy cloth ;-)

A Guide to Teaching Data Science. Five principles they have laid out:

  1. Organize the course around a set of diverse case studies.
  2. Integrate computing into every aspect of the course.
  3. Teach abstraction, but minimize reliance on mathematical notation.
  4. Structure course activities to realistically mimic a data scientist's experience.
  5. Demonstrate the importance of critical thinking/skepticism through examples.

I like the 5th principle. Healthy amount of skepticism in your data and analysis is important :smile:

@evaristoc interesting times we live in. I'll have to take a weekend to watch that film one day :smile:

@apottr awesome! I do most of my wrangling in R, but I'll need to at least get familiar with it in Python as well. Thanks!

I'm sure similar techniques can be applied to R
