Specifically, we first selected models as per business needs after we prepared Spark computing and loaded in preprocessed data. Second, we prepared and reduced features. Third, we estimated model coefficients. Fourth, we evaluated the estimated models. Then, we interpreted the analytical results. And finally, we deployed our estimated models.
The preceding process is similar to the process of working with small data. However, in dealing with big data, we need parallel computing, for which ...
