Re: Does SSVD supports eigendecomposition of non-symmetric & non-positive-semidefinitive matrix better than Lanczos?

Thanks a lot Sebastian, Ted and Dmitriy, I'll try Giraph for a performance benchmark. You are right, power iteration is just the most simple form of Lanczos, it shouldn't be in the scope. On Tue 18 Feb 2014 03:59:57 AM EST, Sebastian Schelter wrote: You can also use giraph for a superfast Page

Re: Does SSVD supports eigendecomposition of non-symmetric & non-positive-semidefinitive matrix better than Lanczos?

You can also use giraph for a superfast PageRank implementation. Giraph even runs on standard hadoop clusters. Pagerank is usually computed by power iteration, which is much simpler than lanczos or ssvd and only gives the eigenvector associated with the largest eigenvalue. Am 18.02.2014 09:33 schr

Re: Does SSVD supports eigendecomposition of non-symmetric & non-positive-semidefinitive matrix better than Lanczos?

Really? I guess PageRank in mahout was removed due to inherited network bottleneck of mapreduce. But I didn't know MLlib has the implementation. Is mllib implementation based on Lanczos or SSVD? Just curious... On 17/02/2014 11:11 PM, Dmitriy Lyubimov wrote: I bet page rank in mllib in spark f
