| Abstract: |
In the last decades more and more all-sky surveys created an enormous amount of data which is publicly available on the Internet.
Crowd-sourcing projects such as Galaxy-Zoo and Radio-Galaxy-Zoo used encouraged users from all over the world to manually conduct various classification tasks.
The combination of the pattern-recognition capabilities of thousands of volunteers enabled scientists to finish the data analysis within acceptable time.
For up-coming surveys with billions of sources, however, this approach is not feasible anymore.
In this work, we present an unsupervised method that can automatically process large amounts of galaxy data and which generates a set of prototypes.
This resulting model can be used to both visualize the given galaxy data as well as to classify so far unseen images. |
