ACL 20232023Methods to generate text from structured data have advanced significantly in recent years, primarily due to fine-tuning of pre-trained lan-guage models on large datasets. However, such models can fail to produce output faithful to the input data, particularly on out-of-domain data. Sufficient annotated data is often not avail-able for specific domains, leading us to seek an unsupervised approach to improve

HCOMP 20232023Video object tracking annotation tasks are a form of complex data labeling that is inherently tedious and time-consuming. Prior studies of these tasks focus primarily on quality of the provided data, leaving much to be learned about how the data was generated and the factors that influenced how it was generated. In this paper, we take steps toward this goal by examining how human annotators spend their

ICCV 20232023We investigate compositional structures in data embeddings from pre-trained vision-language models (VLMs). Traditionally, compositionality has been associated with algebraic operations on embeddings of words from a preexisting vocabulary. In contrast, we seek to approximate representations from an encoder as combinations of a smaller set of vectors in the embedding space. These vectors can be seen as “ideal

IEEE CDC 20232023Robotic sortation centers use mobile robots to sort packages by their destinations. The destination-to-sortlocation (chute) mapping can significantly impact the volume of packages that can be sorted by the sortation floor. In this work, we propose a multi-agent reinforcement learning method to solve large-scale chute mapping problems with hundreds of agents (the destinations). To address the exponential

Winter Simulation Conference 20232023Developing a comprehensive model is a practical approach for gaining insight into and analyzing complex systems such as transportation yards. Following this approach, we have developed a data-driven agentbased model for transportation yards at Amazon which captures the features and processes of yard operations. By simulating different scenarios and using simulation performance indicators such as yard/parking
