In offering a paper for presentation at an IEEE conference or accepting an invitation to present a paper, the author is expected to be present at the meeting to deliver the paper.
In the event that circumstances unknown at the time of submission of a paper preclude its presentation by an author, the technical program chair should be informed on time, and appropriate substitute arrangements should be made.
In some cases, Conferences require authors to register in advance when they submit their final manuscripts.
IEEE policy states that it is up to the Conference Committee’s discretion to allow “no shows” to be published in the IEEE Xplore Digital Library. IEEE Conference Organizers must notify authors prior to, or at time of, submission that their papers may be excluded from IEEE Xplore and the Computer Society Digital Library (CSDL) should they fail to appear at the conference.
The IEEE strongly discourages changes and withdrawals of papers once submitted and included in the program. To avoid the likelihood of this, authors are strongly encouraged to get all necessary company and/or government approvals prior to submitting their papers to conferences.
If under any circumstances it becomes necessary for an author to withdraw or change a paper, IEEE policy dictates that the request to do this must come directly from the author and not from any third party. IEEE policy also states that, in such cases, the author will be held liable for all costs incurred.
It would then be up to the author to get reimbursed for the expense from any third party if he/she feels it is justified. IEEE cannot act as a policing entity on behalf of the author in this regard.
If a change is made to a paper after its acceptance to a conference, IEEE recommends that the Program Committee review the final paper.
