Characteristic Circuits

1 code implementation NeurIPS 2023 Zhongjie Yu, Martin Trapp, Kristian Kersting

In many real-world scenarios, it is crucial to be able to reliably and efficiently reason under uncertainty while capturing complex relationships in data.

Probabilistic Circuits That Know What They Don't Know

2 code implementations13 Feb 2023 Fabrizio Ventola, Steven Braun, Zhongjie Yu, Martin Mundt, Kristian Kersting

In contrast to neural networks, they are often assumed to be well-calibrated and robust to out-of-distribution (OOD) data.

Sum-Product-Attention Networks: Leveraging Self-Attention in Probabilistic Circuits

no code implementations14 Sep 2021 Zhongjie Yu, Devendra Singh Dhami, Kristian Kersting

Probabilistic circuits (PCs) have become the de-facto standard for learning and inference in probabilistic modeling.

Leveraging Probabilistic Circuits for Nonparametric Multi-Output Regression

1 code implementation16 Jun 2021 Zhongjie Yu, Mingye Zhu, Martin Trapp, Arseny Skryagin, Kristian Kersting

Inspired by recent advances in the field of expert-based approximations of Gaussian processes (GPs), we present an expert-based approach to large-scale multi-output regression using single-output GP experts.

When Few-Shot Learning Meets Video Object Detection

no code implementations26 Mar 2021 Zhongjie Yu, Gaoang Wang, Lin Chen, Sebastian Raschka, Jiebo Luo

We employ a transfer-learning framework to effectively train the video object detector on a large number of base-class objects and a few video clips of novel-class objects.

Looking back to lower-level information in few-shot learning

no code implementations27 May 2020 Zhongjie Yu, Sebastian Raschka

In this work, we propose the utilization of lower-level, supporting information, namely the feature embeddings of the hidden neural network layers, to improve classifier accuracy.

TransMatch: A Transfer-Learning Scheme for Semi-Supervised Few-Shot Learning

no code implementations CVPR 2020 Zhongjie Yu, Lin Chen, Zhongwei Cheng, Jiebo Luo

Under the proposed framework, we develop a novel method for semi-supervised few-shot learning called TransMatch by instantiating the three components with Imprinting and MixMatch.
