Data augmentation with Mobius transformations

1 code implementation7 Feb 2020 Sharon Zhou, Jiequan Zhang, Hang Jiang, Torbjorn Lundh, Andrew Y. Ng

Data augmentation has led to substantial improvements in the performance and generalization of deep models, and remain a highly adaptable method to evolving model architectures and varying amounts of data---in particular, extremely scarce amounts of available training data.

DialectGram: Detecting Dialectal Variation at Multiple Geographic Resolutions

1 code implementation4 Oct 2019 Hang Jiang, Haoshen Hong, Yuxing Chen, Vivek Kulkarni

In this work, we propose a model that enables detection of dialectal variation at multiple levels of geographic resolution obviating the need for a-priori definition of the resolution level.
