{quote} k = 1 Otherwise as in the Pegasos article. No parallelism. {quote} I confused. As the consequence, what is the motivation behind integrating the Pegasos into Mahout. Can you estimate that in which situation, this implementation can outperform the original Pegasos? Large-scale data set

Zhao, Mahout is not just for hadoop-based implementations. We are interested in scalable machine learning - we currently have *no* SVM implementations in Mahout, and would welcome an easy simple straightforward SVM, and would find something like the original Pegasos implemented in our APIs

Hi, I see. Thanks for your explanation. I thought that every thing in Mahout should be parallelized. I agree with Ted, to extend k may not obtain any improvement, especially, within the large cluster case. *The lager-scale learning, however, at least has two levels, one is for algorithm and
