# On Latent Position Inference from Doubly Stochastic Messaging Activities

@article{Lee2012OnLP, title={On Latent Position Inference from Doubly Stochastic Messaging Activities}, author={Nam H. Lee and Jordan Yoder and Minh Tang and Carey E. Priebe}, journal={Multiscale Model. Simul.}, year={2012}, volume={11}, pages={683-718} }

We model messaging activities as a hierarchical doubly stochastic point process with three main levels, and develop an iterative algorithm for inferring actors' relative latent positions from a stream of messaging activity data. Each of the message-exchanging actors is modeled as a process in a latent space. The actors' latent positions are assumed to be influenced by the distribution of a much larger population over the latent space. Each actor's movement in the latent space is modeled as…

This work argues that two types of stability in the spatio-temporal positioning of nodes are desirable: to assign the same position to nodes behaving similarly at a given time (cross-sectional stability) and a constant position, up to noise, to a single node behaving similarly across different times (longitudinal stability).

### Mathematical Models and Methods for Behavior in Social Networks: Urban Crime, Self-Exciting Interactions, and Information Spread

- Computer Science

This work considers the problem of filling in missing data in records of communication, formulating it as a variational problem and developing a numerical method to solve it, and adopts a point-process model to reflect observed temporal bursts in communication.

### Community Detection using Locality Statistics

- Computer Science
- 2015

A novel framework for detecting active communities that consist of the most active vertices is proposed, which utilizes a parallelizable trimming algorithm based on a locality statistic to filter out inactive vertices, and then clusters the remaining active Vertices via spectral decomposition of their vertices.

It is found that prediction accuracy is maximized over a non-trivial range of thresholds corresponding to 5-10 reciprocated emails per year and that for any prediction task, choosing the optimal value of the threshold yields a sizable boost in accuracy over naive choices.

The first stage uses simple, conjugate Bayesian models for discrete time counting processes to track the pairwise links of all nodes in the graph to assess normality of behavior, and the second stage applies standard network inference tools on a greatly reduced subset of potentially anomalous nodes.

This paper proposes that the random variation is best described via a Poisson distribution, which better describes the zeros observed in the data as compared to the typical assumption of a Gaussian distribution, and presents a new algorithm for Poisson tensor factorization called CANDECOMP--PARAFAC alternating Poisson regression (CP-APR), based on a majorization-minimization approach.
