Variational Inference for Gaussian Process with Panel Count Data

no code implementations12 Mar 2018 Hongyi Ding, Young Lee, Issei Sato, Masashi Sugiyama

We present the first framework for Gaussian-process-modulated Poisson processes when the temporal data appear in the form of panel counts.

Bayesian Nonparametric Poisson-Process Allocation for Time-Sequence Modeling

1 code implementation19 May 2017 Hongyi Ding, Mohammad Emtiyaz Khan, Issei Sato, Masashi Sugiyama

We model the intensity of each sequence as an infinite mixture of latent functions, each of which is obtained using a function drawn from a Gaussian process.

Misdirected Registration Uncertainty

no code implementations26 Apr 2017 Jie Luo, Karteek Popuri, Dana Cobzas, Hongyi Ding, William M. Wells III, Masashi Sugiyama

Since the transformation is such an essential component of registration, most existing researches conventionally quantify the registration uncertainty, which is the confidence in the estimated spatial correspondences, by the transformation uncertainty.

Reinterpreting the Transformation Posterior in Probabilistic Image Registration

no code implementations7 Apr 2016 Jie Luo, Karteek Popuri, Dana Cobzas, Hongyi Ding, Masashi Sugiyama

Meanwhile, summary statistics of the posterior are employed to evaluate the registration uncertainty, that is the trustworthiness of the registered image.
