Graphical Abstract

Requirements

  • Python 3.7.7
  • tensorflow == 2.7.0
  • tf-keras-vis == 0.6.2
  • matplotlib == 3.5.1
  • opencv-python==4.5.5.62
  • numpy == 1.21.5
  • tqdm == 4.62.3
  • scikit-learn == 1.0.2
  • Pillow == 9.0.1

Use following command pip install -r requirements.txt

Directories

  • test.py : Defined functions to test models.
  • gui.py : Interface Design Code.
  • models : All trained models. models drive link
  • ds : Dataset folder. dataset drive link
  • utils/ : Defined all Custom functions required for Evaluation of Approach.
    1. load_utils.py: Defined functions to load trained models.
    2. cam_utils.py: Defined functions to produce CAMs.
    3. ensemble.py: Defined functions to make ensemble model.
    4. eval_utils.py: All other required functions are defined here.
  • notebooks/ : Contains all Training, Evaluation and Other Notebooks.
    1. proposed student/: Contains proposed model training[with and withour KD] Notebooks.
    2. teacher candidates/: Contains teacher training Notebooks.
    3. ROC_PR_AUC.ipynb: Generate roc-pr plots.

Usage

Below command will open a Interface for testing our models.

python gui.py

To run script with GPU, use below command

python gui.py -g

Two Use Cases of Interface are as follows

  • To Evaluate models [Test Accuracy, Validation Accuracy, FLOPs Count, Parameters Count].
  • To Generate CAMs [Grad CAM, GradCam++, ScoreCam, Faster ScoreCam, Cameras, GuidedBP]

Note1: CAMERAS will take a while to generate cams.

Note2: For NasNetLarge & NasNetMobile use legacy-cameras branch to produce cameras cams.
