Learning Temporal Rules from Noisy Timeseries Data

no code implementations11 Feb 2022 Karan Samel, Zelin Zhao, Binghong Chen, Shuang Li, Dharmashankar Subramanian, Irfan Essa, Le Song

Events across a timeline are a common data representation, seen in different temporal modalities.

Novel Symmetry-preserving Neural Network Model for Phylogenetic Inference

2 code implementations12 Jan 2022 Xudong Tang, Leonardo Zepeda-Nunez, Shengwen Yang, Zelin Zhao, Claudia Solis-Lemus

Scientists world-wide are putting together massive efforts to understand how the biodiversity that we see on Earth evolved from single-cell organisms at the origin of life and this diversification process is represented through the Tree of Life.

ProTo: Program-Guided Transformer for Program-Guided Tasks

1 code implementation NeurIPS 2021 Zelin Zhao, Karan Samel, Binghong Chen, Le Song

Furthermore, we propose the Program-guided Transformer (ProTo), which integrates both semantic and structural guidance of a program by leveraging cross-attention and masked self-attention to pass messages between the specification and routines in the program.
