Compositional Data and Task Augmentation for Instruction Following

no code implementations Findings (EMNLP) 2021 Soham Dan, Xinran Han, Dan Roth

Executing natural language instructions in a physically grounded domain requires a model that understands both spatial concepts such as “left of” and “above”, and the compositional language used to identify landmarks and articulate instructions relative to them.

Transfer Learning for Bayesian Optimization on Heterogeneous Search Spaces

no code implementations28 Sep 2023 Zhou Fan, Xinran Han, Zi Wang

Bayesian optimization (BO) is a popular black-box function optimization method, which makes sequential decisions based on a Bayesian model, typically a Gaussian process (GP), of the function.

HyperBO+: Pre-training a universal prior for Bayesian optimization with hierarchical Gaussian processes

1 code implementation20 Dec 2022 Zhou Fan, Xinran Han, Zi Wang

However, those prior learning methods typically assume that the input domains are the same for all tasks, weakening their ability to use observations on functions with different domains or generalize the learned priors to BO on different search spaces.
