I received the reviews related to my recently submitted conference paper and it is selected as a poster, and there is no rebuttal phase provided. So they do not expect the authors to reply the PCs regarding the results.
However, after reading the reviewers comments clearly (4-5 times) and considering all of them i noticed the following:
1- One of them totally didn't get the main purpose and the domain of the paper and held a strong opposition against it.
2- The 2 Others were happy about the novelty and the results, but one of them asked for comparing to other methods (which i believe they are not applicable to my studied problem), and more analysis (which i already did in the paper and he may have missed it)
So if i had the chance to send a rebuttal letter i definitely would have taken that to send a sound, well-reasoned counterargument (but polite) regarding the above points.
But i'm afraid doing so could be considered inconvenient and even be harmful (leading to a rejection)!
