Do I need to add more servers if my user load grows by 10% each month for the next 12 months? That is a hard question to answer. Unless you have an Application Platform Management solution, it is hard to correlate function calls to CPU time and response times.
I find that machine learning experiment’s results are always interesting and somewhat unexpected in certain cases. On this comparison, the feature ranking results of PFI are often different from the feature selection statistics that are utilized before a model is created. This is useful in many cases, especially when training “black-box” models where it is difficult to explain how the model characterizes the relationship between the features and the target variable.
