Latent Embeddings of Point Process Excitations

  journal={arXiv: Machine Learning},
When specific events seem to spur others in their wake, marked Hawkes processes enable us to reckon with their statistics. The underdetermined empirical nature of these event-triggering mechanisms hinders estimation in the multivariate setting. Spatiotemporal applications alleviate this obstacle by allowing relationships to depend only on relative distances in real Euclidean space; we employ the framework as a vessel for embedding arbitrary event types in a new latent space. By performing… Expand


Learning Triggering Kernels for Multi-dimensional Hawkes Processes
This paper focuses on the nonparametric learning of the triggering kernels, and proposes an algorithm MMEL that combines the idea of decoupling the parameters through constructing a tight upper-bound of the objective function and application of Euler-Lagrange equations for optimization in infinite dimensional functional space.

Learning Multivariate Hawkes Processes at Scale
A novel model and computational approach is proposed to compute the exact likelihood and gradients of an MHP -- independently of the ambient dimensions of the underlying network by exploiting a characteristic sparsity pattern in real-world diffusion processes. Expand
Latent self-exciting point process model for spatial-temporal networks
An efficient approximate algorithm based on variational expectation-maximization to infer unknown participants in an event given the location and the time of the event is developed. Expand
The Neural Hawkes Process: A Neurally Self-Modulating Multivariate Point Process
This generative model allows past events to influence the future in complex and realistic ways, by conditioning future event intensities on the hidden state of a recurrent neural network that has consumed the stream of past events. Expand
Generative Sequential Stochastic Model for Marked Point Processes
Temporal point processes are often used to model event data streams in the real world, such as financial transactions, electronic health records, and social networks. While several parametricExpand
Mutually Regressive Point Processes
This paper introduces the first general class of Bayesian point process models extended with a nonlinear component that allows both excitatory and inhibitory relationships in continuous time and derives a fully Bayesian inference algorithm for these processes using Polya-Gamma augmentation and Poisson thinning.

Learning Network of Multivariate Hawkes Processes: A Time Series Approach
The problem of recovering the causal structure in network of multivariate linear Hawkes processes, which encodes the causal factorization of the joint distribution of the processes, is studied and it is shown that the resulting causal influence network is equivalent to the Directed Information graph (DIG).

Uncovering Causality from Multivariate Hawkes Integrated Cumulants
We design a new nonparametric method that allows one to estimate the matrix of integrated kernels of a multivariate Hawkes process. This matrix not only encodes the mutual influences of each nodes ofExpand
Learning Hawkes Processes from a Handful of Events
This work develops an efficient algorithm based on variational expectation-maximization that significantly outperforms state-of-the-art methods under short observation sequences and is able to optimize over an extended set of hyper-parameters. Expand
Learning Granger Causality for Hawkes Processes
An effective learning algorithm combining a maximum likelihood estimator (MLE) with a sparse-group-lasso (SGL) regularizer is proposed that can learn the Granger causality graph and the triggering patterns of the Hawkes processes simultaneously. Expand
