Hi mlandry22,
First of all, I see that you're quite an advanced programmer from your fluent codes in R, Python and MATLAB 👍

Can you please guide me as to how I can create/ get the Train.csv and other input files that you have used in your GBM code(s)?

P.S.: I'm new to GBM, R and GitHub repository.
Thanks.

Hi, I was wondering if you could explain the reasoning behind the way wTx inner product is being implemented in the get_p method. From reading the code it seems that the x features that have been hashed are not being used in the computation of the weight vector. Shouldn't the the inner product of the predict function be wTx = w[i] * i, which would follow along the lines of a typical logistic regression computation? Because currently it looks like it is just summing the computed weights, with no affect from the actual feature vector.
