Described how data mining can help identify radio
galaxies with bent-double morphology
Illustrated specific data mining steps
– data pre-processing is very crucial
In our experience, data mining is semi-automatic
– interaction and feedback required at many stages
– domain knowledge is essential
Multi-disciplinary collaboration is challenging, but
rewarding
– astronomy - computer science - statistics
There is always room for improvement
– alternative techniques
– your feedback welcome!
