Machine learning

Machine Learning is a subdomain of Artificial Intelligence centered around the idea that machines can be trained to recognize patterns based on annotated input data. In the context of maps and OSM, a common application is to annotate a sample set of imagery (aerial or street-level) in order to automatically derive information and/or map features from a larger dataset.

Applications

This is a list of existing applications of Machine Learning designed to support OSM.

Relevant Training Data

  • https://github.com/greatea/Telenav.AI offers "45 000 manually annotated images containing more than 55 000 signs divided in 23 different classes". A sample dataset with 1000 images is also available.
  • Mapbox allows all users to use Mapbox Satellite images for machine learning processes[1]
