2021 was a dividing line for major AI conferences. Transformers spread from NLP throughout computer vision and time-series research, self-supervised learning became the most common cross-conference theme, and a diffusion model won an ICLR Outstanding Paper award before anyone realized it would displace GANs. Meanwhile, GNNs and federated learning reached historic peaks in paper volume before beginning to decline.
