What does the ML in Lemmy ML stand for?

I asked this as a comment on my previous post, but I still have some questions. 1: If ML stands for Mali and they're not from Mali, then why would they represent a foreign country? 2: Since it's not Mali, what does the ML stand for? If it's a pair of letters, it represents a country or stands for two words. Machine Learning? McCartney Lennon? Mega Lemmy?
