We consider the problem of estimating the parameters in a pairwise graphical model in which the distribution of each node, conditioned on the others, may have a different exponential family form. We… Expand
The Multivariate Hawkes Process in High Dimensions: Beyond Mutual Excitation
- Shizhe Chen, A. Shojaie, Eric T. Shea-Brown, D. Witten
- Mathematics
- 16 July 2017
The Hawkes process is a class of point processes whose future depends on their own history. Previous theoretical work on the Hawkes process is limited to a special case in which a past event can only… Expand
Neural Granger Causality for Nonlinear Time Series
- A. Tank, Ian Covert, N. Foti, A. Shojaie, E. Fox
- Mathematics
- 16 February 2018
While most classical approaches to Granger causality detection assume linear dynamics, many interactions in applied domains, like neuroscience and genomics, are inherently nonlinear. In these cases,… Expand
Metabolomic profiling reveals potential markers and bioprocesses altered in bladder cancer progression.

- Biology, Medicine
- Cancer research
- 15 December 2011
Although alterations in xenobiotic metabolism are considered causal in the development of bladder cancer, the precise mechanisms involved are poorly understood. In this study, we used high-throughput… Expand
