Artificial Intelligence

What you should know about this indicator

  • AI conferences serve as essential platforms for researchers to present their findings and network with peers and collaborators.
  • Over the past two decades, these conferences have expanded in scale, quantity, and prestige.
  • Attendance data should be interpreted with caution, as many conferences in recent years have adopted virtual or hybrid formats.
  • Virtual conferences often attract larger and more global audiences, but exact attendance figures are harder to measure.
  • The AI Index reports total attendance, including virtual, hybrid, and in-person participation, across conferences such as AAAI, NeurIPS, ICML, CVPR, EMNLP, ICLR, and others.
  • The significant spike in ICML attendance in 2021 was likely due to the conference being held virtually that year.

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.
