Modeling Events with Cascades of Poisson Processes
We present a probabilistic model of events in continuous time in which each event triggers a Poisson process of successor events. The ensemble of observed events is thereby modeled as a superposition of Poisson processes. Efficient inference is feasible under this model with an EM algorithm. Moreover, the EM algorithm can be implemented as a distributed algorithm, permitting the model to be app...

Modeling Events in Time using Cascades of Poisson Processes by Aleksandr Simma Doctor of Philosophy in Computer Science and the Designated Emphassis in Communication, Computation, and Statistics University of California, Berkeley Professor Michael I. Jordan, Chair For many applications, the data of interest can be best thought of as events – entities that occur at a particular moment in time, h...
متن کاملTrans-dimensional Bayesian non-parametrics with spatial point processes
Point processes are a class of models where the notion of variable dimension is inherent. The main part of this discussion is concerned with the application of marked point processes as prior models in nonparametric Bayesian function estimation, reformulating and revising earlier joint work with Elja Arjas and listing some other related work (Section 2). Accordingly, the discussion is centered ...
متن کاملBayesian non-parametrics for multi-modal segmentation
Segmentation is a fundamental and core problem in computer vision research which has applications in many tasks, such as object recognition, content-based image retrieval, and semantic labelling. To partition the data into groups coherent in one or more characteristics such as semantic classes, is often a first step towards understanding the content of data. As information in the real world is ...
متن کاملCompound Poisson Cascades
Multiplicative processes and multifractals proved useful in various applications ranging from hydrodynamic turbulence to computer network traffic. Placing multifractal analysis in the more general framework of infinitely divisible laws, we design processes which possess at the same time stationary increments as well as multifractal and more general infinitely divisible scaling over a continuous...
