NeurIPS'18 Workshop Presentations

This year at NeurIPS in Montreal, I have three workshop papers. Together with my colleagues, I will present at:

AAAI'19 paper accepted

Our new paper Efficient Gaussian Process Classification Using Polya-Gamma Data Augmentation got accepted at AAAI in Honolulu, Hawaii. We propose an augmented perspective on a GP classification model based on Polya-Gamma variables. The augmented model is conjugate and inference is much faster than in former approaches. We publish the code in our Julia package AugmentedGaussianProcesses – a library for fast inference in non-conjugate GP models based on data augmentation.

ICML'18 paper accepted

Our paper Quasi-Monte Carlo Variational Inference was accepted at ICML. In this paper we explore the usage of Quasi-Monte Carlo sampling for obtaining low variance gradient estimators for Monte Carlo variational inference.

AISTATS'18 paper accepted

I am happy that our paper Generalized Dynamic Topic Models got accepted at AISTATS in Lanzarote. We generalize the classic topic model to topics which evolve other time. The time dynamics are modeled by Gaussian processes. Choosing different kernels for the GPs allows for discovering different time patterns in the text corpus.

Netflix Travel Award / NIPS'17

Our workshop paper Scalable Logit Gaussian Process Classification got selected as contributed talk at the Advances in Approximate Bayesian Inference Workshop at NIPS. Moreover, I am very happy to receive the Netflix Travel Award.
