Query: MEDUSA: Multi-scale Encoder-Decoder Self-Attention Deep Neural Network
  Architecture for Medical Image Analysis   Medical image analysis continues to hold interesting challenges given the
subtle characteristics of certain diseases and the significant overlap in
appearance between diseases. In this work, we explore the concept of
self-attention for tackling such subtleties in and between diseases. To this
end, we introduce MEDUSA, a multi-scale encoder-decoder self-attention
mechanism tailored for medical image analysis. While self-attention deep
convolutional neural network architectures in existing literature center around
the notion of multiple isolated lightweight attention mechanisms with limited
individual capacities being incorporated at different points in the network
architecture, MEDUSA takes a significant departure from this notion by
possessing a single, unified self-attention mechanism with significantly higher
capacity with multiple attention heads feeding into different scales in the
network architecture. To the best of the authors' knowledge, this is the first
"single body, multi-scale heads" realization of self-attention and enables
explicit global context amongst selective attention at different levels of
representational abstractions while still enabling differing local attention
context at individual levels of abstractions. With MEDUSA, we obtain
state-of-the-art performance on multiple challenging medical image analysis
benchmarks including COVIDx, RSNA RICORD, and RSNA Pneumonia Challenge when
compared to previous work. Our MEDUSA model is publicly available.
