Black in AI exists to create a space for sharing ideas, foster collaborations, and discuss initiatives to increase the presence of Black individuals in the field of AI. To this end, we hold an annual technical workshop series, run mentoring programs, and maintain various fora for fostering partnerships and collaborations with and among black AI researchers. The 4th Black in AI workshop and 1st virtual Black in AI workshop will consist of selected oral presentations, invited keynote speakers, a joint poster session with other affinity groups, sponsorship sessions, and socials. Our workshop exists to amplify the voices of black researchers at NeurIPS.
