I'll never understand why China spent so much time and money finding the perfect remote karst for radio astronomy and then built a radio-loud amusement park around it.

>FAST is also receiving an enormous amount of weak radio frequency interference(RFI). Machine learning techniques were used to mitigate the RFI collected by FAST. This observation served as a test observation and it demonstrated that the majority of RFI was filtered out by the machine learning algorithm and the signal ranking pipeline called Nebula is also compatible with the observational data generated from FAST.
