UniTS: Building a Unified Time Series Model

2 code implementations29 Feb 2024 ShangHua Gao, Teddy Koker, Owen Queen, Thomas Hartvigsen, Theodoros Tsiligkaridis, Marinka Zitnik

However, current foundation models apply to sequence data but not to time series, which present unique challenges due to the inherent diverse and multidomain time series datasets, diverging task specifications across forecasting, classification and other types of tasks, and the apparent need for task-specialized models.

Domain Adaptation for Time Series Under Feature and Label Shifts

1 code implementation6 Feb 2023 Huan He, Owen Queen, Teddy Koker, Consuelo Cuevas, Theodoros Tsiligkaridis, Marinka Zitnik

Additionally, the label distributions of tasks in the source and target domains can differ significantly, posing difficulties in addressing label shifts and recognizing labels unique to the target domain.

Deep Learning for Reference-Free Geolocation for Poplar Trees

no code implementations31 Jan 2023 Cai W. John, Owen Queen, Wellington Muchero, Scott J. Emrich

A core task in precision agriculture is the identification of climatic and ecological conditions that are advantageous for a given crop.

Evaluating Explainability for Graph Neural Networks

1 code implementation19 Aug 2022 Chirag Agarwal, Owen Queen, Himabindu Lakkaraju, Marinka Zitnik

As post hoc explanations are increasingly used to understand the behavior of graph neural networks (GNNs), it becomes crucial to evaluate the quality and reliability of GNN explanations.
