similar to: NDCG in R?

Hi John, I was posting the position on behalf of another team within my group, DCG.  The scope of the work is fairly broad and is closely related to the type of work we do with LLVM, but I don't believe the potential candidate will work directly on LLVM (at least that's not the immediate plan).  I apologize if I've somehow misused the mailing list; that was certainly not my

Will do, Chris! Again, my apologizes.

Hi, there ! I'm pretty sure that the following text (and attached picture) explains the reason for the gain of high frequencies. when quantizing a vector scalar by scalar by simply rounding each scalar to the nearest level, the quantization-error-vector and the original signal-vector can be assumed to be orthogonal (average case) This is a problem when we want to preserve the energy level

All, The Data Center Group is seeking exceptional engineers to work on optimizing just-in-time (JIT) compilers for virtual machines for our server based platforms.  The responsibilities of this position include analyzing workloads to determine bottlenecks, utilize strong knowledge of our micro-architecture to improve performance and work with the open source communities to drive target

I'm developing an R package, and when I recompile (using Roxygen), detach, and re-load the package, I can't seem to look at some of its documented functions. When I try '?function.name', I get the following error: Error in tools:::fetchRdDB(RdDB, basename(file)) : cannot allocate memory block of size 2.6 Gb I'm using R.app's built-in documentation viewer. I

Hi Parth, I have a few questions- 1. Could you please provide me with the link for query-file, qrel-file for the dataset available at http://www.mpi-inf.mpg.de/departments/d5/software/inex/ . 2. I wanted to know how automated testing would be implemented. Will there be test cases like a test query must match this particular N results and this particular ranking. Or will it be in terms of

Hi, Before starting my proposal, I wanted to know what is the expected output of Letor module. Is it for transfer learning (i.e you learn from one dataset and leverage it to predict the rankings of other dataset) or is it for supervised learning? For instance - Xapian currently powers the Gmane search which is by default based on BM25 weighting scheme and now suppose we want to use LETOR to rank

Hi, I have several questions regarding the letor module,I looked at the framework of learning to rank in xapian http://rishabhmehrotra.com/gsoc/17.png, I am a little confused. Why using deep learning to find unsupervised features in test data? Since in my understanding, learning to rank model usually learn features from the training data then apply the model to the test data? Why test set and

Hello all, This is in reference to "Learning to Rank" Project Idea. [I know, i made the entry a bit late, but hope you are still in interest to help out] I am looking for suggestions to help me narrowing down the choices of algorithms. I had been readily surveying on the referred algorithms for the purpose of choosing the right one. I am mentioning here some of my doubts to discuss and

Hello, I am Uppinder Chugh (irc nick: icebyte), a senior year undergraduate student majoring in Computer Science and Engineering at Indian Institute of Technology, Guwahati. I'm interested to work on the idea of adding the functionality of search result diversification to Xapian. After having brief conversations with mentors on IRC, I would like to compile the discussions and further discuss

I have searched for the actual answer to this repeatedly, but keep coming up with different answers. Most people say that it just "can't be done" but then, once in a while, someone seems to reply that they are doing it and it works fine. Which messes up that whole "it can't be done" argument. :) Basically, we have a network with a Windows 2000 Small Business server,
