I've used madlib[1] before and was quite happy with that. Maybe you can do a feature comparison with similar existing solutions as many people don't have the bandwidth to go through your documentations.
That's a good idea, thanks! What kinds of problems were you solving with madlib?
Classification problems in a medical domain. It literally took me 30 minutes to install madlib and run logistic regression on a table. It then probably took me a few more days to do some analysis, try out various algorithms and productionize the predictor.
A feature comparison with other solutions is a great idea. We'll work on that and share here.
