Event-Keyed Summarization

1 code implementation10 Feb 2024 William Gantt, Alexander Martin, Pavlo Kuchmiichuk, Aaron Steven White

We introduce event-keyed summarization (EKS), a novel task that marries traditional summarization and document-level event extraction, with the goal of generating a contextualized summary for a specific event, given a document and an extracted event structure.

Jurassic World Remake: Bringing Ancient Fossils Back to Life via Zero-Shot Long Image-to-Image Translation

1 code implementation14 Aug 2023 Alexander Martin, Haitian Zheng, Jie An, Jiebo Luo

In this work, we use text-guided latent diffusion models for zero-shot image-to-image translation (I2I) across large domain gaps (longI2I), where large amounts of new visual features and new geometry need to be generated to enter the target domain.

An Online-Learning Approach to Inverse Optimization

no code implementations30 Oct 2018 Andreas Bärmann, Alexander Martin, Sebastian Pokutta, Oskar Schneider

We also introduce several generalizations, such as the approximate learning of non-linear objective functions, dynamically changing as well as parameterized objectives and the case of suboptimal observed decisions.
