HuggingFace adds support for Perceiver IO
Key point
Perceiver IO, a scalable multimodal model that can process any kind of data, has been added to the Transformers library.
Details
Perceiver IO is a Transformer-based neural network that can process a wide range of modalities—text, images, audio, video, point clouds—and combinations thereof.
To address the key limitation of conventional Transformers, the quadratic complexity of self-attention, it applies attention not to the input data but to latent variables.
Since most computation takes place in the low-dimensional latent space, computational cost can be managed efficiently regardless of input size, giving it a linear dependency on input size.
It has been integrated into HuggingFace's Transformers library and can be used via the PerceiverModel class, flexibly handling various data formats through a preprocessor, decoder, and postprocessor.
