WebA point process generalized linear model (PP-GLM) framework for the estimation of discrete time multivariate nonlinear Hawkes processes is described. The approach is illustrated with the modeling of collective dynamics in neocortical neuronal ensembles recorded in human and non-human primates, and prediction of single-neuron spiking. WebAug 9, 2024 · Goodness‐of‐fit testing in high dimensional generalized linear models. We propose a family of tests to assess the goodness of fit of a high dimensional generalized linear model. Our framework is flexible and may be used to construct an omnibus test or directed against testing specific non‐linearities and interaction effects, or for ...

Webmation, which often requires estimating a high dimensional joint distribution, it suffices to learn the support of the exci-tation matrix. Our second contribution is indeed providing an estimation method for learning the support of excitation matrices with exponential form using second-order statis-tics of the Hawkes processes.

Linear hypothesis testing for high dimensional generalized linear models
WebFeb 9, 2024 · For the more general class of non-linear Hawkes processes, [35] proves the process-level large deviations, and [36] derives large deviations in the Markovian setting. ... WebSep 20, 2024 · For linear smoothers and linear-predictor based sampling estimators, Mercer Kernels are a highly convenient tool for fitting linear decision boundaries in high dimensional feature spaces. In fact, such feature spaces can even be infinitely dimensional (as we will show). WebWe consider high-dimensional generalized linear models with Lip-schitz loss functions, and prove a nonasymptotic oracle inequality for the empirical risk minimizer with Lasso penalty. The penalty is based on the coefficients in the linear predictor, after normalization with the empirical norm. The examples include logistic regression, density es- first governor of commonwealth of virginia
