We have built a set of pre-trained models called Generic Autodidactic Models, nicknamed Models Genesis, because they are created ex nihilo (with no manual labeling), self-taught (learned by self-supervision), and generic (served as source models for generating application-specific target models). We envision that Models Genesis may serve as a primary source of transfer learning for 3D medical imaging applications, in particular, with limited annotated data.

Paper

This repository provides the official implementation of training Models Genesis as well as the usage of the pre-trained Models Genesis in the following paper:

Major results from our work

  1. Models Genesis outperform 3D models trained from scratch
  2. Models Genesis top any 2D approaches, including ImageNet models and degraded 2D Models Genesis
  3. Models Genesis (2D) offer performances equivalent to supervised pre-trained models

The par plots presented below are produced by Matlab code in figures/plotsuperbar.m and the helper functions in figures/superbar. Credit to superbar by Scott Lowe.

Note that learning from scratch simply in 3D may not necessarily yield performance better than ImageNet-based transfer learning in 2D
