For a machine learning researcher, the conference year is set by paper deadlines, not by ticket sales. You submit in the summer or autumn, hear back months later, and only then book travel. Lists that mix these venues with look-alike "International Conference on" listings do not help you plan any of that.
This page covers the research and systems venues with official 2027 dates: AAAI-27, ICLR, CVPR, MLSys and ICML. For each you get the dates, the city, the paper deadline where it is published, and whether registration is open. Most of these post fees close to the event, so the table often says Not announced.
Dates, cities and ticket prices in the table come from each organizer's official site, checked on 5 Nov 2026. If an organizer has not published a 2027 price, the table says Not announced. Prices move, so confirm the live figure at checkout. The method is on How we review tools.
AAAI-27
AAAI-27 is the annual conference of the Association for the Advancement of Artificial Intelligence. It covers AI research broadly, with machine learning as one large part.
Best for: Researchers whose work spans machine learning and other AI fields. Academic groups that want a February conference.
Dates and city: February 16-23, 2027. Palais des congrès de Montréal, per the accommodation page. In-person.

- The days overlap with MLSys in nearby Bellevue. You will have to choose.
Tickets: Not announced. The dates page lists no registration opening.
Can I still submit to CVPR 2027?
Yes, if you move fast. Paper registration closes November 10, 2026 and full submissions close November 16, 2026, Anywhere on Earth. Check the call for papers for the exact rules.
MLSys 2027
MLSys is the research conference on machine learning and systems.
Best for: ML infrastructure engineers and systems researchers. Startups building training or inference tooling who want to meet the authors behind the papers.
Dates and city: June 21-25, 2027, Bellevue, Washington. Young Professionals Symposium June 21, conference sessions June 22-24, Industry Day June 25. The site does not post a venue yet.
What you actually get: Three days of research sessions plus an Industry Day. The Industry Day makes it more useful for practitioners than a pure paper venue.
Notable limitations:
- The paper deadline has passed. Submissions closed October 30, 2026 at 2:00 PM PDT. Author notifications are listed for February 28, 2027.
- The days overlap with CVPR in Seattle.
Tickets: Not announced. The dates page lists no registration dates.
ICML 2027
ICML, the International Conference on Machine Learning, is one of the three large ML research venues. In 2027 it goes to Rio de Janeiro.
Best for: Researchers presenting papers. Industry labs recruiting. Teams who want a summer research venue.
Dates and city: July 31 to August 6, 2027. Riocentro, Rio de Janeiro, Brazil. Expo day July 31, tutorials August 1, main conference August 2-4, workshops August 5-6.
What you actually get: Seven days with a clear split: an expo day, a tutorial day, three days of main conference and two of workshops.
Notable limitations:
- The paper deadlines are not on the ICML 2027 dates page yet. Watch the call for papers.
- A long flight for most of North America, Europe and Asia. Check entry rules for Brazil early.
Tickets: Not announced. The dates page lists no registration opening.
Still to come in 2026
NeurIPS 2026 runs December 6-12, 2026 in Sydney (main site), with main conference days December 8-10. Satellites run December 9-13 in Atlanta and Paris, with main conference days December 9-11. Registration has reopened for the remaining Sydney and Atlanta spots at neurips.cc/Register. Fees depend on your affiliation (industry, academic or full-time student) and on the events you register for. Early pricing ended October 30, 2026, and the official pricing page lists the current late rates. Paris has its own pricing and registration at neurips-europe.cc. A virtual-only pass is also sold.
Other machine learning conferences worth considering
NeurIPS 2027 has no dates on the official site yet. Expect the call for papers to set your spring.
ODSC AI West is a practitioner option in California. The official page still shows the 2026 edition and a 2027 waitlist. No dates yet.
KDD 2027, the data mining conference, runs August 1-5 in San Jose, starting the day after ICML opens in Rio. It is on our data science conferences page.
How we picked these conferences
We listed the machine learning research and systems venues with official exact dates in 2027, and applied the same rule to each one. A missing fee did not exclude a venue. Applied data mining and statistics events sit on our data science page so the lists do not repeat. Dates, deadlines and fees were checked on the organizers' sites on 5 Nov 2026. In the From column, a number is a price we read on the official ticket page, with VAT shown as the site states it. Not announced means the organizer has not published a 2027 price yet. Expo-only, virtual-only and free application passes are described in the event sections, not the table.
FAQs
Should a startup send engineers to ICLR or ICML?
If you hire researchers or ship research-heavy products, yes. The workshops and the recruiting are the value. If your team mostly uses models through APIs, an industry event fits better. Our AI conferences page covers those.
Which 2027 deadline is still open?
CVPR 2027. Paper registration closes November 10, 2026 and submissions close November 16, 2026, Anywhere on Earth. AAAI-27, ICLR 2027 and MLSys 2027 have closed. ICML 2027 has not posted its deadlines on the dates page.
Why are 2027 fees missing?
The organizers have not published them. None of the five 2027 dates pages lists a registration fee or opening date. We do not guess.
Is there a virtual option?
NeurIPS 2026 sells a virtual-only pass. The 2027 venues have not posted virtual options yet.
Where are the analytics and data platform events?
Gartner Data & Analytics Summit and FabCon are on our big data conferences page.
Bottom line
If you publish, plan around the deadlines first. CVPR is the one still open, with submissions due November 16, 2026. Then pick by field: AAAI-27 in February for broad AI, ICLR in April for deep learning, CVPR or MLSys in June, and ICML in Rio from late July. Book travel once fees and venues are posted.
