Doubt regarding Feature selection for 'Learning to Rank' algorithms
...tested in the experimental settings. Though it may be a wonderful research exercise, I would still vote to go for the state-of-the-art methods which are completely published with full details and experimental results. Hope you get my point. Regards, Parth.

Covariate model in nlme
...lationships between CL and covariate is linear and given as the following equation. CL=TVCL+a*wt-b*age, where TVCL is mean clearance, a and b are coefficients of weight and age, respectively. How do I write this in nlme to estimate TVCL, a and b? Any input would be appreciated.

Mid-term progress
Hi Rishabh, As per our last progress meeting, I am off for some days and as now its the time to mid-term evaluation, it would be better to generate a progress report. For that, you should first commit the code as it is and then write 2 to 3 page summary explaining the deliverables so far and then the future plan. Tomorrow is the last day, so better by tomorrow morning, send this across and by

A Little Help
...List to the following statement in this method. std::map<Xapian::docid, double> letor_score(const Xapian::MSet & mset); So just convert the RankList in std::map<Xapian::docid, double> format in the methods where you need to return.

Patch: New features for Learning to Rank
Hello, Please find attached the patch which contains new features for the LETOR framework which increases the total features from 19 to 37. In my proposal I had mentioned of having a final count of 44 IR specific features apart from those learnt by unsupervised feature learning part via Deep Learning. So I am left with 7 out of those 44,of which 6 I will be implementing within the next 2

I tried installing it using the Rkward GUI, but can't write to any of the pre-set directories because of permissions issues. When I try running
