Dear Experts and Data Scientist,

I need to know the detail method or reference to solve or learn about following questions:

a) I am working on classification problem of predicting the purchase of Y based on 22 features.

out of these 22 features, two features are in exponential form (i.e 8.05+E+12), so how to use these for classification using Random Forest and Logistic Regression.

b) in the same problem of part a above, out of these 22 features I have two features containing dates , so how to use these dates in Random Forest and Logistic Regression.

I have used

as.numeric(as.date(data$F15)), but this resulted in negative numbers.

c) what kind of data type for independent variable or feature is valid for using random forest for classification task.

hoping for the answer as early as possible.

thank you
