I'm interested in tensor factorization using GraphLab. I'm trying to follow the instruction in the user manual (at the bottom of http://select.cs.cmu.edu/code/graphlab/pmf.html, copied below), however, the link for the sample data is broken.
Is the data file no longer available? If not, is there any sample file that can be used for tensor factorization?
Running example: BPTF (Bayesian monte carlo matrix factorization) using Twitter social graph This example was donated by Timmy Wilson @ smarttypes.org. It contains a twitter network of 68 followers, 11646 followies, 1 day and 15883 links. Download the input file here
