Co-creator of Metacademy here. Colorado and I are intending Metacademy to be a “package manager for knowledge,” where you can easily find the particular thing you want to learn about (e.g. deep neural nets) without having to track down all the prerequisites (e.g. gradient descent) yourself. Basically, we’ve annotated a dependency graph for the core concepts in the field, and it uses the graph to produce step-by-step…

Awesome site, and want to support any way we can. Great context around content sources both free and paid are really promising.

Let me know if we can be at all of help: darrell [at] thinkful.com

This is awesome. I can see this, if it gets larger, being a ton of help throughout college.

Is there a way to view the DAG of concepts itself?

Not sure if you can see the whole thing, but you can see big chunks of it by selecting an advanced concept and clicking the graph button in the sidebar.

I like the approach! I feel that search could use an improvement. I'm using k-means++ at the moment for something and searched for "k-means" which yield no results [1]. I clicked on the link to look at the full-list and found k-means mentioned 3 times, to my surprise.

Was it the two of you who added all the content? Did you do it all manually? How long did it take?

I think this is fantastic. Obviously stuff to be ironed out, tidied up and better organised but genuinely think this is a great idea, how does one go about developing something like the dependency graph? Would love to implement it in a site I am building while learning Rails.

This is a dream, thank you.
