Data annotation done right: easy, fun, hyper-productive, and inducing insight.
Project description
Hover
[
Hover
is a machine teaching library that enables intuitive and effecient supervision. In other words, it provides a map where you hover over and label your data... differently. For instance, you can:
- :seedling: annotate an intuitively selected group of data points at a time
- :whale: cross-check with Snorkel-based distant supervision
- :ferris_wheel: UPCOMING throw a model in the loop and take advantage of active learning
Check out @phurwicz/hover-binder for a complete list of demo apps.
Features
Here we attempt a quick comparison with a few other packages that do machine teaching:
Package | Hover |
Prodigy |
Snorkel |
---|---|---|---|
Core idea | supervise like painting a picture | scriptable active learning | programmatic distant supervision |
Annotates per | batch of just the size you find right | piece predicted to be the most valuable | the whole dataset as long as it fits in |
Supports | all classification (text only atm) | text & images, audio, vidio, & more | text classification (for the most part) |
Status | open-source | proprietary | open-source |
Devs | indie | Explosion AI | Stanford / Snorkel AI |
Related | many imports of the awesome Bokeh |
builds on the Thinc /SpaCy stack |
Variants: Snorkel Drybell , MeTaL , DeepDive |
Vanilla usage | define a vectorizer and annotate away | choose a base model and annotate away | define labeling functions and apply away |
Advanced usage | combine w/ active learning & snorkel | patterns / transformers / custom models | transforming / slicing functions |
Hardcore usage | exploit hover.core templates |
custom @prodigy.recipe | the upcoming Snorkel Flow |
Hover
claims the best deal of scale vs. precision thanks to
- the flexibility to use, or not use, any technique beyond annotating on a "map";
- the speed, or coarseness, of annotation being literally at your fingertips;
- the interaction between multiple "maps" that each serves a different but connected purpose.
