Scalability has become one of those core concept slash buzzwords of Big Data. It’s all about scaling out, web scale, and so on. In principle, the idea is to be able to take one piece of code and then throw any number of computers at it to make it fast. The terms “scalable” and “large scale” have been used in machine learning circles long before there was Big Data. There had always been certain problems which lead to a large amount of data, for example in bioinformatics, or when dealing with large number of text documents. So finding learning algorithms, or more generally data analysis algorithms which can deal with a very large set of data was always a relevant question. … Scalable Machine Learning google
