Please read these instructions carefully and follow them exactly to minimize problems with production of the conference proceedings. All papers that are submitted on time, which are compliant with IEEE Xplore, and for which the IEEE copyright has been completed, will be placed in IEEE Xplore can be considered archival.

#### 2. Modify the copyright notice, if needed.

Change the appropriate copyright notice to the bottom of the first page as needed.

• For papers in which all authors are employed by the US government, the copyright notice is: U.S. Government work not protected by U.S. copyright
• For papers in which all authors are employed by a Crown government (UK, Canada, and Australia), the copyright notice is: 978-1-6654-3780-6/21/$31.00 @2021 Crown • For papers in which all authors are employed by the European Union, the copyright notice is: 978-1-6654-3780-6/21/$31.00 @2021 European Union
• For all other papers, the copyright notice is: 978-1-6654-3780-6/21/$31.00 @2021 IEEE To change the copyright notice in your latex file, look for the following lines (line 26-40) and uncomment the necessary line as needed. \makeatletter \def\ps@IEEEtitlepagestyle{ \def\@oddfoot{\mycopyrightnotice} \def\@evenfoot{} } \def\mycopyrightnotice{ {\hfill \footnotesize 978-1-6654-3780-6/21/\$31.00 \copyright 2021 IEEE\hfill}
%% Uncomment following line for papers in which all authors are employed by the US government
%{\hfill \footnotesize U.S. Government work not protected by U.S. copyright\hfill}
%% Uncomment following line for papers in which all authors are employed by a Crown government (UK, Canada, and Australia)
%{\hfill \footnotesize 978-1-6654-3780-6/21/\$31.00 \copyright 2021 Crown\hfill} %% Uncomment following line for papers in which all authors are employed by the European Union %{\hfill \footnotesize 978-1-6654-3780-6/21/\$31.00 \copyright  European Union\hfill}
}

Proofread your source document thoroughly to confirm that it will require no revision.

Please ensure that you use the appropriate copyright notice, which appears at the bottom in the first column of the first page.

#### 3. Validate your paper using PDF eXpress

• Log in to the IEEE PDF eXpress Login Page: https://ieee-pdf-express.org/
• Enter the following: 52358X for the Conference ID.
• If you have not used PDF eXpress before, you must create an account. Click the & New User & button and follow the instructions. If you have used PDF eXpress for a previous conference, you can log in using your previous email address and password; it will then ask you to create an account for this conference by entering a password–it can be the same password. Verify (and update if necessary) your contact information and click & Submit. Once you have an account, you can login as often as you need to process all of your papers.
• Create a new title for each paper that you are submitting.
• Submit the PDF file you wish to validate, or submit the source files you wish to convert. PDF eXpress will digest the file(s) submitted and send you an e-mail with the validation result, or the generated PDF, as appropriate. Repeat this step until you are satisfied with the result.

Note: It is our understanding that 90% of the failed validations are due to font embedding issues. If your validation fails, make sure that embeddable fonts are used exclusively, including the captions and text of figures and tables. If you Google & pdf express problem & you will find plenty of advice on how to fix validation problems.

You cannot skip the validation step. IEEE will revalidate every file we submit for inclusion in IEEE Xplore, and will not fix or ingest files that fail validation. If it’s not ingested, it is not archivable – which means your paper will not appear in IEEE Xplore.

If you encounter any problems, contact the Publications Support Center for IEEE PDF eXpress via Live Chat or the Submission Form.

If your problems are not yet resolved even after your best efforts, contact Kiran Raja at kiran.raja@ntnu.no or Emanuela Marasco  at emarasco@gmu.edu

#### 4. Final paper submission for production

• Login to the CMT paper collection site: https://cmt3.research.microsoft.com/IJCB2021/
• Prepare and validate your camera-ready submission as described in Steps 1-3. The name of your camera-ready submission must be in the form XXXX.pdf where XXXX is the four-digit paper ID (zero-padded if necessary). For example, if your paper ID is 24, the filename must be 0024.pdf. Rename your camera-ready PDF file that was validated by PDF eXpress and upload it after clicking on the “Create Camera Ready Submission” link.
The final PDF submission should be 8 pages (or less) including figures, tables and references  less than 100MB in size; must be validated by PDF eXpress; and should be uploaded to the CMT web site (after validation) by July 1, 2021 at 11:59pm Pacific Time.
• To finalize the paper submission process, you must next complete and submit the IEEE Electronic Copyright Form as described in Step 5 below. If you upload a paper more than once, the paper collection site will remember that you have already filled out the copyright form for that paper and so you don’t have to resubmit the electronic copyright form.

#### 5. Submit the IEEE Copyright form

Complete and (a) digitally sign the IEEE Electronic Copyright Form for your paper [You can click the link “Submit IEEE Copyright Form” in the column “Actions” after you login as an author at https://cmt3.research.microsoft.com/IJCB2021, and then follow the instructions.] (b) download it and (c) submit it along with your final paper.

If you have completed the form but forgot to download the PDF Copyright file, it is also sent by email to you.

IMPORTANT: Please ensure that your paper title is correct and that the author names and affiliation details are correctly recorded in the CMT system prior to completing the IEEE electronic copyright form. You will not be able to redo the form once it is submitted.

Papers without completed copyright forms will not appear on the conference proceedings disk and will not be included in IEEE Xplore.
