The PDF of the paper can be found at: https://arxiv.org/abs/1907.13372

The webpage of the paper is: https://lttm.dei.unipd.it/paper_data/IL/

• Download the pretrained model of the Deeplab-v2 architecture pretrained on MSCOCO from: https://drive.google.com/drive/folders/0B_rootXHuswsZ0E4Mjh1ZU5xZVU and place it inside the folder pretrained/
• Download the Pascal VOC dataset or your desired dataset and process it with the provided scripts for pre-processing (further info at sample_dataset/README.txt).
  • For a quick start simply download the tfrecords folder provided from the webpage of the paper (https://lttm.dei.unipd.it/paper_data/IL/) and place it in sample_dataset/
  • Alternatively, download the Pascal VOC 2012 and run sample_dataset/build_data.bat which will create 4 tfrecords files in sample_dataset/tfrecords/

I suggest to start from the folder codes/LD1/ where you can run the simulations for the incremental scenario in which only the last class is added and only the LD1 loss is present.
The procedure is discussed in detail at codes/LD1/README.txt.
NB: for the other folders no README.txt exists since they are straightforward extensions of the code contained in the LD1/ folder

• the code has been tested on Tensorlfow 1.10 - 1.14
• the vast majority of the experiments have been conducted on a computer with:
  • processor: Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz, 3701 Mhz, 6 Core(s), 12 Logical Processor(s)
  • RAM: 32 GB
  • OS: Microsoft Windows 10 Pro Education
  • GPU: NVIDIA GeForce RTX 2080 Ti, 11GB

I can provide checkpoints, datasets or other material upon specific request.
