My paper recently got accepted in a non-archival workshop at a prominent computer science conference. Since it is non-archival, should I still pay author registration (which is between $500 to $1000) to do a virtual oral paper presentation that is less than 15 minutes? That seems like I am paying for the merit to present my work at the workshop instead of my work being worthy enough to be presented...
Nobody can answer this question for you. It's like asking "Should I pay $1M for a Matisse?" The answer depends on two factors:
- Do you have the money?
- How much is having a Matisse worth to you?
The same applies to your question: Assuming you have the resources to pay in the first place, how much is presenting at this conference (and participating in it as well -- there are also talks to listen to) worth to you? We really cannot tell you, it's a question for you to figure out.
