@evaristoc any advice for prerequisites on the book? For I saw it hardly explains some of the concepts. Even for entry level I am curious what I miss. Sometimes I read advanced math books and I can follow along. This book I can't because it implies a lot. So any tip is welcome. Discovered a bit about topology, Markov Models dimensional reduction. Sometimes I can find good readable introductions like for non math persons. But I saved it for later. Balancing between time consuming coding and math is like juggling 😱

@evaristoc beauty tip: a warm towel will open your pores. That should help with your osmosis problem

@alicejiang1 :) :) :) beauty tip! I was planning to use an avocado mask, but not enough avocado for my face...

@mesmoiron :) this book in my opinion doesn't need more requirements than the basics. Some analytics would come handy but a good understanding of Gaussian distribution, and Euclidean representation in a multidimensional space, specifically hypervolumes, and sampling in a multidimensional space, would be useful.
Then some graph algorithms would be also handy.

I would eat all the avocado
Couple questions: Someone suggested a website that I can't remember the name of. It's similar to Kaggle but has "data" in the name... ring any bells for anyone?
and I was recently at a meetup where they announced they would be beginning a data science class using a coursera course that teaches R. I don't know much about this group but I know there's a strong emphasis on programming in what they do, and their target demographic for this class is people starting at point 0. Am I wrong to be a bit concerned that people without strong statistical backgrounds are going to be trying to teach newbies R?
That learning curve is rough for me and I wasn't starting at 0 when I first started learning it

As a little background on the group: it's a non-profit that helps people without formal education or professional experience prepare for and get jobs in technology, and they are just now adding in this course to help people get jobs in DS. With what I know about DS and R, I don't feel like I wouldn't have much confidence in learning either from a some non-DS programmers using a coursera MOOC as their guide if I were coming into this with no foundation...

@alicejiang1 I think you are asking for Datacamp

Ok... hmmm... hard: looking for a site in google using "data" as keywork is not going to help much...
But I think I know which you are talking about... I think I checked the link too...

@alicejiang1 I will let you know if I remember. The coursera course I think is this one? No a bad one.

I don't recall which course. I was only half paying attention, but I know that whatever it was was free.
