similarity because all the more visual recognition tasks another example maybe the tasks you want to solve is a few shot regression problem you have a few examples of input-output pairs but then your meta training tasks consist of other curve fitting problems so other curves with a few sample input-output pairs or maybe you have some kind of speech recognition task or some kind of language translation task and so on so in all these cases you can formulate a set of meta training tasks that are not the same as the tasks you want to solve
