They were developed independently for different purposes:

  1. Perceivers: Developed by DeepMind in 2021, Perceivers were created to generalize the transformer model to handle various input types (like images, audio, text) in a uniform way. This approach allows processing of different modalities and input sizes without task-specific architectures, using a fixed-size latent space.
  2. Informers: Developed by researchers at Tsinghua University and other institutions in 2020, Informers are designed to improve the efficiency of transformers for long sequence time-series forecasting. They address the challenge of computational complexity in handling long sequences with innovations like ProbSparse self-attention, enabling the model to focus on the most relevant parts of the input.
