The Surprising Positive Knowledge Transfer in Continual 3D Object Shape Reconstruction

Note: This forked repo is outdated, please see the original repo here.

In this work we investigate continual learning of reconstruction tasks which surprisingly do not suffer from catastrophic forgetting and exhibit positive forward knowledge transfer. In addition, we provide a novel analysis of knowledge transfer ability in CL. We further show the potential of using the feature representation learned in 3D shape reconstruction to serve as a proxy task for classification. Link to our paper and link to our project webpage.

This repository consists of the code for reproducing CL of 3D shape reconstruction, proxy task and autoencoder results.
