DeepMind's Perceiver and Perceiver IO: New data family architecture

Visiting AI & ML Research Seminar

58:58·2022·graduate level

Drew Jaegle presents DeepMind's Perceiver and Perceiver IO, exploring an asymmetric attention mechanism that allows these architectures to scale to high-dimensional and multimodal data without domain-specific assumptions, outperforming standard Transformers.

A central goal of artificial intelligence is to build systems that can flexibly process all the world's data, but current neural network architectures are designed to handle essentially one data configuration. This includes models like 2D convnets and more recent Vision Transformer models, which scale well on images but can be challenging to apply to other data. In this talk, I'll be describing Perceivers, a new family of architectures that scale well to many kinds of high-dimensional data while making essentially no domain assumptions. Perceivers leverage an asymmetric attention mechanism to encode and decode data from a latent bottleneck. This mechanism allows Perceivers to handle inputs and outputs several orders of magnitude larger than can be used with standard Transformers. Using this architecture, we obtain performance comparable to or better than domain-specific architectures on a wide range of tasks, including image classification, natural language understanding, optical flow, multimodal autoencoding & classification, set processing, and multi-task learning.
