Hover

Explore and label on a map of raw data.

Get enough to feed your model in no time.

PyPI Version Conda Version Downloads Main Build Status Nightly Build Status Codacy Grade Codacy Coverage

hover speeds up data labeling through embedding + visualization + callbacks.

  • You just need raw data and an embedding to get a map.
  • Explore the map to find "zones" that are easy and those that are tricky.
  • Start the conquest of your data by coloring the zones through wisdom!

🚀 Live Demos

With code

  • edit & run code in your browser to get a labeling interface, with guides along the way.

Without code

  • go directly to a labeling interface, pre-coded and hosted on Binder.

✨ Features (click bullets to show GIF)

It's fast because it labels data in bulk.

🔭 A semantic scatter plot of your data for labeling, equipped with

  • Tooltip for each point on mouse hover

  • Table view for inspecting all selected points

  • Toggle buttons that clearly distinguish data subsets

  • Search widgets for ad-hoc data highlight

It's accurate because multiple angles work together.

🔬 Supplementary views to use in conjunction with the annotator, including

  • Finder: filter data by search criteria

  • Softlabel: active learning by in-the-loop model prediction score

  • Snorkel: custom functions for labeling and filtering

It's flexible (and fun!) because the process never gets old.

:toolbox: Additional tools and options that allow you to

  • Go to higher dimensions (3D? 4D?) and choose your xy-axes

  • Consecutively select across areas, dimensions, and views

  • Kick outliers and fix mistakes

💡 Click on the bullet points above to view GIFs!

  • Thanks to Philip Vollet for sharing hover with the community even when it was really green.

Contributing

  • All feedbacks are welcome, especially what you find lacking and want it fixed!
