Purpose of the project

This software is a research prototype, solely developed for and published as part of the publication "What Matters For Meta-Learning Vision Regression Tasks?". It will neither be maintained nor monitored in any way.

Requirements, test, install, use, etc.

Installation

• install CUDA10.1
• clone the repo using git lfs

  git lfs clone https://github.com/boschresearch/what-matters-for-meta-learning.git
  cd what-matters-for-meta-learning

• setup environment

  conda create -n mlvr python=3.7.9 pip
  conda activate mlvr
  pip install -r requirements.txt

Datasets

Extract Distractor, ShapeNet1D, ShapeNet3D datasets and background images used for ShapeNet3D from data/, Pascal1D dataset can be generated following prior work Meta-Learning without Memorization. Extract all datasets under data/, datafolder should be structured as:

data/
├── distractor/
├── ShapeNet1D/
├── ShapeNet3D_azi180ele30/
├── Pascal1D/
├── bg_images.npy
dataset/
networks/
...

Models

We provide three pretrained models for: distractor task with CNP + max aggregation, ANP for Shapenet1D task and Shapenet3D. Download the models from here and extract under results/train/.

Evaluation

evaluate and visualize predictions on distractor task:

python evaluate_and_plot_distractor.py --config cfg/evaluation/eval_and_plot/${config file}

evaluate and visualize on ShapeNet1D:

python evaluate_and_plot_shapenet1d.py --config cfg/evaluation/eval_and_plot/${config file}

evaluate and visualize predictions on ShapeNet3D:

python evaluate_and_plot_shapenet3d.py --config cfg/evaluation/eval_and_plot/${config file}

statistical evaluation on novel tasks:

python evaluation.py --config cfg/evaluation/${config file}

Training

Some training config examples are provided in cfg/train/, you can also play around and change parameters with different combinations.

Training distractor task requires 32GB memory to load all category datasets:

python train.py --config cfg/train/${Distractor_script}

for example, if you want to traing ANP with DA and TA for distractor task:

python train.py --config cfg/train/ANP_DA+TA_Distractor.yaml

Refine on Single Task:

Adapt the load model path in config file and run:

python refinement.py --config cfg/refinement/${single_task_config}
