So why label a dataset piece by piece?

Hover

• A bird's-eye view: plot your dataset in 2D with tooltips

  • Explore the dataset "from above" while being able to inspect every detail.
  • Know how much data has been labeled for each category, and where they are in the whole picture.

• Seamless switch between speed and precision

  • Come up with labels as you inspect the data, no need to pre-define them.
  • Identify & label groups of data of any shape or scale.
    • Found a big cluster? Draw an area and .
    • Need to go at finer scale? Zoom in and tap one by one if necessary.

• Facilitation of common supervision techniques

  • Got an idea for keywords (if working with text)? Type in the search box to highlight results.
  • Facing a cold start for ? Explore here and there to label a few clusters.
  • Want to evaluate some rules? Visualize how they perform.
