I searched for “Julia for data science” and got these 2 hits. Are these good places to learn from:
They wrote the book on it!
Yes those are good spots.
In addition to the great resources you’ve already found, Bogumił Kamiński, a powerhouse Julia developer who is a principal contributor to Julia’s DataFrames.jl package, is soon publishing a book, Julia for Data Analysis. Looks like it won’t be out until September, but it will almost certainly be a great resource.
In the meantime, Mr. Kamiński gave a great tutorial on the use of DataFrames in Julia at last year’s JuliaCon. I’m not a data scientist, but I found it to be very helpful.
