Project description
Semi-Supervised Data Programming for Data Efficient Machine Learning
SPEAR is a library for data programming with semi-supervision. The package implements several recent data programming approaches including facility to programmatically label and build training data.
Pipeline
- Design Labeling functions(LFs)
- generate pickle file containing labels by passing raw data to LFs
- Use one of the Label Aggregators(LA) to get final labels
SPEAR provides functionality such as
- development of LFs/rules/heuristics for quick labeling
- compare against several data programming approaches
- compare against semi-supervised data programming approaches
- use subset selection to make best use of the annotation efforts
- facility to store and save data in pickle file
Labelling Functions (LFs)
- discrete LFs - Users can define LFs that return discrete labels
- continuous LFs - return continuous scores/confidence to the labels assigned
Approaches Implemented
You can read this paper to know about below approaches
- Only-L
- Learning to Reweight
- Posterior Regularization
- Imply Loss
- CAGE
- Joint Learning

Acknowledgment
SPEAR takes inspiration, builds upon, and uses pieces of code from several open source codebases. These include Snorkel, Snuba & Imply Loss. Also, SPEAR uses SUBMODLIB for subset selection, which is provided by DECILE too.
Team
SPEAR is created and maintained by Ayush, Abhishek, Vineeth, Harshad, Parth, Pankaj, Rishabh Iyer, and Ganesh Ramakrishnan. We look forward to have SPEAR more community driven. Please use it and contribute to it for your research, and feel free to use it for your commercial projects. We will add the major contributors here.
