Update

• [√] Release the training and evaluation code on Pascal-VOC 2012 for EWF.
• Init code for Classification with EWF.
• Add ADE20K training scripts for EWF.

Benchmark and Settings.

There are two kinds of settings proposed in this field, disjoint and overlapped. Since overlapped is a more realistic setting, we only conduct experiments on this scenario. Nevertheless, the readers are encouraged to test our method on different settings in disjoint scenario and compare them with other methods. Plus, we call each training on the newly added dataset as a step. Formally, X-Y denotes the continual setting in our experiments, where X denotes the number of classes that we need to train in the first step. In each subsequent learning step, the newly added dataset contains Y classes.

Dataset Preparation

• PASCAL VOC 2012

sh data/download_voc.sh

• ADE20K

sh data/download_ade.sh

Environment

1. Please intall the environment according to environment.yml.
2. Install inplace-abn

Training

1. Dowload pretrained model from ResNet-101_iabn to pretrained/
2. We have prepared some training scripts in scripts/. You can train the model by

sh scripts/voc/plop+ours_15-1.sh
