user31998: I am working on the Yusupov series. In the first book he introduces Anastasia and Arabian among others. What I am a little uncertain about is the following issues.

How do you remember them?
How do you classify them?

I guess I am unsure about what defines a mate, especially when they are more vague than smothered/Philidor. Anastasia for example is quite vague. Are all rook+knight mates Arabian mate?

user32195: As @Brian Towers said, remembering their names is nearly obsolete. But categorising them may help in recognising them, especially when an individual is new to chess.

But I would suggest you to consider them as miscellaneous tactics, as there can be many mating patterns possible other than the named ones.

user4418: 
How do you remember them?

Generally speaking I make no effort to remember their names because they have very little use. In terms of remembering the patterns they are like any tactical motif like forks, pins, skewers, overloading, etc.

How do you classify them?

Again, except for obscure things like writing a book this is almost useless. Classifying them doesn't help me play better so I don't waste my time trying to do that.
