Explaining reviews and ratings with PACO: Poisson Additive Co-Clustering [article]

Chao-Yuan Wu, Alex Beutel, Amr Ahmed, Alexander J. Smola
2015 arXiv   pre-print
With this novel technique we propose a new Bayesian model for joint collaborative filtering of ratings and text reviews through a sum of simple co-clusterings.  ...  In contrast, in this paper, we attack this problem through succinct additive co-clustering. We devise a novel Bayesian technique for summing co-clusterings of Poisson distributions.  ...  Poisson Additive Co-Clustering While ACCAMS [3] explains the ratings matrix well, it does not utilize the reviews associated with those ratings.  ...

Wireless network signals with moderately correlated shadowing still appear Poisson [article]

Nathan Ross, Dominic Schuhmacher
2016 arXiv   pre-print
We provide bounds on the distance between the point process of signal strengths and a Poisson process with the same mean measure, assuming correlated log-normal shadowing.  ...  In our model, transmitters are placed deterministically or randomly according to a hard core or Poisson point process and signals are subjected to power law path loss and random propagation effects that  ...  Acknowledgments Yu-Hsiu Paco Tseng assisted in running simulations, funded by a University of Melbourne Vacation Scholarship.  ...
