Although the details are scant, from what I understand it is just an addition/change in the Bitdefender cloud that allows it to analyse malware files more efficiently. However, they have hyped it up to something extremely innovative and game changing, when it is basically just new machine learning algorithms implemented. If you want to really understand what is happening in Bitdefender, I recommend you to read up on some of the machine learning techniques implemented by Bitdefender.
I don't use Bitdefender, but from the details given in Bitdefender's press release I think you can turn it off by disabling Bitdefender's cloud protection. Not sure if you can turn off the cloud protection though.
