Description of Folders

• datasets: This folder should hold the raw datasets used for the project.
• export: This folder is for files that include models.
• result: This folder is for pretrained model parameters
• mats: This directory stores MATLAB-related files, such as .mat files or other results generated during computation.
• your script: Your script should be placed at the same level as 'export'

Usage Guide for dulrs Package

The dulrs package provides tools to calculate and visualize some evaluation matrix (heatmap, low-rankness, sparsity)of our models on various scenarios from different datasets.

The dulrs_class.lowrank_cal function in the dulrs package allows users to calculate and save the low-rankness data with mat format.

3. dulrs_class.lowrank_draw(model_name, data_name, mat_dir, save_dir)

The dulrs_class.lowrank_draw function in the dulrs package allows users to draw the low-rankness figure based on the calculated low-rankess data and save with png format.

4. dulrs_class.sparsity_cal(img_path, model_name, data_name, save_dir)

The dulrs_class.sparsity_cal function in the dulrs package allows users to calculate and save the sparsity data with mat format.
