Kamino: Constraint-Aware Differentially Private Data Synthesis

1 code implementation31 Dec 2020 Chang Ge, Shubhankar Mohapatra, Xi He, Ihab F. Ilyas

Existing differentially private data synthesis methods aim to generate useful data based on applications, but they fail in keeping one of the most fundamental data properties of the structured data -- the underlying correlations and dependencies among tuples and attributes (i. e., the structure of the data).

Ruler: Data Programming by Demonstration for Document Labeling

no code implementations Findings of the Association for Computational Linguistics 2020 Sara Evensen, Chang Ge, Cagatay Demiralp

Data programming aims to reduce the cost of curating training data by encoding domain knowledge as labeling functions over source data.

Data Programming by Demonstration: A Framework for Interactively Learning Labeling Functions

1 code implementation3 Sep 2020 Sara Evensen, Chang Ge, Dongjin Choi, Çağatay Demiralp

We operationalize our framework with Ruler, an interactive system that synthesizes labeling rules for document classification by using span-level annotations of users on document examples.

Multi-task Generative Adversarial Learning on Geometrical Shape Reconstruction from EEG Brain Signals

2 code implementations31 Jul 2019 Xiang Zhang, Xiaocong Chen, Manqing Dong, Huan Liu, Chang Ge, Lina Yao

In light of this, we propose a novel multi-task generative adversarial network to convert the individual's EEG signals evoked by geometrical shapes to the original geometry.
