Big Data: Enterprise Class Machine Learning with Spark and MLbase

Machine Learning is a critical part of extracting value from Big Data. Choosing proper model, preparing data and getting usable results on large scale data is non-trivial exercise. Typically process consists of model prototyping using higher level, (mostly) single machine based tool like R, Matlab, Weka, then coding in Java or some other language for large scale deployment. This process is fairly involved, error prone, slow and inefficient. Existing tools aiming at automating and improving this process are still somewhat immature and wide scale Machine Learning enterprise adopti... (more)
