FeatAug: Automatic Feature Augmentation From One-to-Many Relationship Tables

1 code implementation11 Mar 2024 Danrui Qi, Weiling Zheng, Jiannan Wang

To overcome this limitation, we propose FEATAUG, a new feature augmentation framework that automatically extracts predicate-aware SQL queries from one-to-many relationship tables.

Are We Ready For Learned Cardinality Estimation?

2 code implementations12 Dec 2020 Xiaoying Wang, Changbo Qu, Weiyuan Wu, Jiannan Wang, Qingqing Zhou

The results show that learned models are indeed more accurate than traditional methods, but they often suffer from high training and inference costs.

Complaint-driven Training Data Debugging for Query 2.0

1 code implementation12 Apr 2020 Weiyuan Wu, Lampros Flokas, Eugene Wu, Jiannan Wang

As the need for machine learning (ML) increases rapidly across all industry sectors, there is a significant interest among commercial database providers to support "Query 2. 0", which integrates model inference into SQL queries.

Encoding CT Anatomy Knowledge for Unpaired Chest X-ray Image Decomposition

1 code implementation16 Sep 2019 Zeju Li, Han Li, Hu Han, Gonglei Shi, Jiannan Wang, S. Kevin Zhou

We hereby propose a decomposition generative adversarial network (DecGAN) to anatomically decompose a CXR image but with unpaired data.

ActiveClean: Interactive Data Cleaning While Learning Convex Loss Models

no code implementations15 Jan 2016 Sanjay Krishnan, Jiannan Wang, Eugene Wu, Michael J. Franklin, Ken Goldberg

Data cleaning is often an important step to ensure that predictive models, such as regression and classification, are not affected by systematic errors such as inconsistent, out-of-date, or outlier data.
