IEEE FG 20212021We present a new approach for synthesizing novel views of people in new poses. Our novel differentiable renderer enables the synthesis of highly realistic images from any viewpoint. Rather than operating over mesh-based structures, our renderer makes use of diffuse Gaussian primitives that directly represent the underlying skeletal structure of a human. Rendering these primitives gives results in a high-dimensional

NeurIPS 2021 Workshop on Explainable AI Approaches for Debugging and Diagnosis2021We typically compute aggregate statistics on held-out test data to assess the generalization of machine learning models. However, test data is only so comprehensive, and in practice, important cases are often missed. Thus, the performance of deployed machine learning models can be variable and untrustworthy. Motivated by these concerns, we develop methods to generate and correct novel model errors beyond

NeurIPS 2021 Workshop on Distribution Shifts2021Recent work has unveiled how average generalization frequently relies on superficial patterns in data. The consequences are brittle models with poor performance in the presence of domain shift in group distribution at test time. When the subgroups in the training data are known, we can use tools from robust optimization to tackle the problem. However, group annotation and identification are time-consuming

ASRU 20212021End-to-end automatic speech recognition (ASR) systems are increasingly popular due to their relative architectural simplicity and competitive performance. However, even though the average accuracy of these systems may be high, the performance on rare content words often lags behind hybrid ASR systems. To address this problem, second-pass rescoring is often applied leveraging upon language modeling (LM).

VLDB 20212021Multi-source entity linkage focuses on integrating knowledge from multiple sources by linking the records that represent the same real world entity. This is critical in high-impact applications such as data cleaning and user stitching. The state-of-the-art entity linkage pipelines mainly depend on supervised learning that requires abundant amounts of training data. However, collecting well-labeled training
