ASRU 20212021Recent years have seen significant advances in end-to-end (E2E) spoken language understanding (SLU) systems, which directly predict intents and slots from spoken audio. While dialogue history has been exploited to improve conventional text-based natural language understanding systems, current E2E SLU approaches have not yet incorporated such critical contextual signals in multi-turn and task-oriented dialogues

NeurIPS 2021 Workshop on I (Still) Can't Believe It's Not Better2021We consider the problem of probabilistic forecasting over categories with graph structure, where the dynamics at a vertex depends on its local connectivity structure. We present GOPHER, a method that combines the inductive bias of graph neural networks with neural ODEs to capture the intrinsic local continuous-time dynamics of our probabilistic forecasts. We study the benefits of these two inductive biases

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
