What will be the number of attendees at NeurIPS 2019?

This question is related to the 2019 ICML and CVPR conference attendance question, however ICML and CVPR occur together in June, so we split them into their own question instead of delaying resolution until NeurIPS in December.


As reported by the AI Index (p. 26 of the 2018 report), the number of attendees at major machine learning conferences has grown exponentially since the start of the ML revolution in 2011.

As of 2018, the three largest conferences are Neural Information-Processing Systems (NeurIPS), International Conference on Machine Learning (ICML) and Computer Vision and Pattern Recognition (CVPR).

NeurIPS 2019 takes place in Vancouver in December. ICML 2019 and CVPR 2019 take place back-to-back in Long Beach, CA, in June.

Now we ask:

What will be the number of attendees at NeurIPS 2019?


Resolution

Resolution will be determined by an attempt to get attendee estimates directly from conference organisers (as done by the AI Index), or by a credible report of such an estimate from the organisers.

Note also that 1) the data is based on estimates from the conference organisers, and not actual counts (hence why NeurIPS 2018 data is exactly "8000"); 2) due to constraints imposed by things like the size of venues, tail-end attendance figures might be a poor proxy for demand.


Data

Underlying data on conference attendees going back to the 1980’s can be found in this spreadsheet.

Most recent values have been:

2018: 8000

2017: 7755

2016: 5230

Metaculus help: Predicting

Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.

The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available.

The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.

Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Note: this question resolved before its original close time. You earned points up until the question resolution, but not afterwards.

Thanks for predicting!

Community Stats

Metaculus help: Community Stats

Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.

When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
