Determinantal Point Processes for Machine Learning [PDF]
Determinantal point processes (DPPs) are elegant probabilistic models of repulsion that arise in quantum physics and random matrix theory. In contrast to traditional structured models like Markov random fields, which become intractable and hard to ...

Deep Mixture Point Processes: Spatio-temporal Event Prediction with Rich Contextual Information [PDF]
Predicting when and where events will occur in cities, like taxi pick-ups, crimes, and vehicle collisions, is a challenging and important problem with many applications in fields such as urban planning, transportation optimization and location-based ...

DECOMPOSING IMAGES INTO TRIANGLES BY DELAUNAY POINT PROCESSES [PDF]
We propose a method for decomposing images into triangles. Contrary to superpixel methods, our output representation both preserves the geometric information disseminated in input images, and has an attractive storage capacity.

Rank-Based Mixture Models for Temporal Point Processes
Temporal point process, an important area in stochastic process, has been extensively studied in both theory and applications. The classical theory on point process focuses on time-based framework, where a conditional intensity function at each given ...

Point processes with Gaussian boson sampling. [PDF]
Random point patterns are ubiquitous in nature, and statistical models such as point processes, i.e., algorithms that generate stochastic collections of points, are commonly used to simulate and interpret them.

Revealing Spectrum Features of Stochastic Neuron Spike Trains
Power spectra of spike trains reveal important properties of neuronal behavior. They exhibit several peaks, whose shape and position depend on applied stimuli and intrinsic biophysical properties, such as input current density and channel noise.

A Variational Auto-Encoder Model for Stochastic Point Processes [PDF]
We propose a novel probabilistic generative model for action sequences. The model is termed the Action Point Process VAE (APP-VAE), a variational auto-encoder that can capture the distribution over the times and categories of action sequences.

DETECTING LINEAR FEATURES BY SPATIAL POINT PROCESSES [PDF]
This paper proposes a novel approach for linear feature detection. The contribution is twofold: a novel model for spatial point processes and a new method for linear feature detection.
