• I already have an account, but the system says I do not.

  I already have an account, but the system says I do not.

   

  The ICML.cc, OpenReview and CMT websites are completely separate each with their own accounts. We request you use the same email address for both because it makes it easier for us to link accepted papers to ICML.cc accounts. 

  You may have an account under a diferent email check this page.

• How do I change my email address?

  How do I change my ICML.cc login email address?
   

  Visit the Contact ICML page located under the ICML menu to send a request to change your email address. Please include the both the existing email address and the new address. 

  If you have two icml.cc acounts that you want to perge visit this page

   

• I have two icml.cc accounts, can they be merged?

  I have more than one ICML.cc account can they be merged?

   

  Each ICML.cc account/profile has only one email address. Many people have multiple email addresses and as a result the can end up with multiple ICML.cc accounts.

  A common situation is that you submitted a paper on OpenReview/CMT with an email that is different than your ICML.cc account email. When we import accepted papers we create accounts for authors who do not have an account with the email that they used on OpenReview/CMT. ICML.cc, CMT and OpenReview are all separate systems so the only way we have of linking accounts between them is by email address

  We recommend that you merge your accounts so that all you registrations and papers are in a single account. To merge your accounts visit the MergeAccounts page. 

• Why I am no longer receiving email from icml.cc?

  Why am I receiving email from ICML.cc?

  In an effort to fite spam companies and ISP's have implemented aggressive methods which can sometimes catch icml.cc email. If you need a copy of your receipt use this form to contact support

• Why do i not see all my events and papers, where are they?

  I do not see all my events or papers

   

  Main conference papers

  There are 2 likely explanations:

  1. You used different email addresses on ICML.cc and OpenReview. When we import papers, we create ICML.cc accounts when we see a new email address. You can try logging in with the other email address. You may also merge two different ICML.cc accounts (email addresses) with MergeAccounts.
  2. There may have been another problem linking the data to your account. Please report the problem to the appropriate organizing committee member, or contact us.

  Workshop papers

  • If you do not see your workshop paper listed in your profile then you need to contact the organizers of that workshop (not the workshop chairs) and ask them to add your paper to their schedule

• Safety at the Conference

  Safety Tips for Attendees and Exhibitors

  • Always verify surprise repair calls at your hotel with the front desk or hotel security (i.e., plumbing or electrical repairs).
  • Cameras and camcorders are open invitations to be robbed.
  • Carry a list of important telephone numbers.
  • Do not carry or show large amounts of cash.
  • Do not stop on the road to ask directions. Go where known help is available (i.e., service station, fire station, etc.).
  • Dress like a local. (Maybe not that flashy)
  • If your car is bumped, do not get out or stop. Go to a safe area to call the police.
  • Remove your name badge once you leave your meeting.
  • Rental cars should not be identified as such.
  • Treat your booth like your place of business.
  • Treat your hotel room like your home. Lock your doors
  • Walk in groups, especially at night.
  • Do not bring your passport to the convention center. Lock it in your hotel safe. We accept a credit card as a form of ID.

Credit Card Payments

• How is my credit card information protected?

  How is my credit card information protected?

  Your information is protected by TLS encryption between your browser and the card processor. We never know or even handle your credit card number and we are PCI compliant.

• Where is my credit card refund?

  Where is my refund? I should have received a refund by now, but it's not on my credit card activity.

  Thanks to the wonderful workings of the credit card networks, refunds can take 10 business days or longer to post to your account. In some cases, non US banks can delay the refund even longer.  If you still haven't received a refund after 4-5 weeks, please contact us.

• Why was my credit card payment declined?

  Why was my credit card payment declined?

  If the website does not tell you the problem, there is regrettably little we can do to help. For security reasons, banks will not answer questions from anyone other than the account holder. If you cannot get the payment to go through, we recommend either you contact your issuing bank, or use a different card.

  If you are using an institutional or government credit card you may need to contact the responsible department to pre-authorize your charge. In previous years some registrants have run into problems with cards that are restricted to a very limited set of merchants or require advance notice on transactions over a certain amount.

  Exhibitor FAQ’s

   

  Q: How do I access the Exhibitor Portal?

  A: Please click on the Green button with your company name on the home page. See image below:

  

  Q: How do I get an invoice for payment? 

  A: Click on “Send Invoice” in the exhibitor portal. Verify the information, including the PO number is correct (if applicable). Then click the button to email to yourself. If your company requires the invoice to come from the conference, please notify us immediately. 

   

  Q: What happens if the invoice information is incorrect?

  A: The invoice is auto-generated from the information you’ve entered in the “your information” section of the application. If you need name changes, a PO number added, etc., please update your information section, refresh the page, click on the “Send Invoice” tab, and send to yourself.

   

  Q: How can other members of my team gain access to the exhibitor portal? 

  A: They must create a profile on the website first. Then you can add them to the exhibitor badge section, click save. They will notice the same green tab on their homepage that is shown on the first Q/A on this sheet.

   

  Q: How do I get access to the attendee list?

  A: You will not have access to the Opt-In attendee list until we have received a signed contract and payment from your company. Once we have these items, you will see a BLUE “Recruitment Information” tab in the exhibitor portal. Once you click that, a window pops up where you can download an Excel sheet and a Zip folder of CV’s for your recruitment efforts. See image below

  

   

   

  Q: Does the conference have a lead scanning system? 

  A: Yes! This is built into the exhibitor portal and you will have access once the signed contract is submitted and we have received payment. Until then, please review our Wiki page with specific instructions on how it works. No app or scanning device required.

   

  Q: Who gets access to lead scanning? 

  A: Only the team members who have been entered into the exhibitor badge section of the portal will have access. If someone from your team needs a full conference registration but also wants access to lead scanning then you may add them to both sections. 

   

  Q: What if my company needs additional exhibitor badges or full conference registrations?

  A: The conference does not sell additional exhibitor badges. Your company will need to purchase any type of registration (usually the cheapest) to gain access to the exhibit hall. If your company needs additional full conference registrations then those will need to be purchased at the company’s expense. 

   

  Q: How come my logo won’t upload in the portal? 

  A: The only file accepted is an svg file. Be sure you are using the correct format. If the file you are uploading isn’t an svg file, please work with your team to create one. 

   

  Q: Is the Certificate of Insurance (COI) required?

  A: Yes! Even if you have an exhibitor appointed contractor (EAC). The COI we are asking for is liability insurance for your employees who will be working the booth at the conference venue, which is not the same as the COI for an EAC. Be sure to upload before the deadline. 

   

  Q: What if my company doesn’t carry general liability insurance?
  A: You will need to work with your company to find an international general liability insurance career.

   

  Q: Can my company get a breakdown of attendee demographics?
