dcase2024_task2_evaluator

The dcase2024_task2_evaluator is a script for calculating the AUC, pAUC, precision, recall, and F1 scores from the anomaly score list for the evaluation dataset in DCASE 2024 Challenge Task 2 "First-Shot Unsupervised Anomalous Sound Detection for Machine Condition Monitoring."

https://dcase.community/challenge2024/task-first-shot-unsupervised-anomalous-sound-detection-for-machine-condition-monitoring

Description

The dcase2024_task2_evaluator consists of two scripts:

• dcase2024_task2_evaluator.py
  • This script outputs the AUC and pAUC scores by using:
    • Ground truth of the normal and anomaly labels
    • Anomaly scores for each wave file listed in the csv file for each machine type, section, and domain
    • Detection results for each wave file listed in the csv file for each machine type, section, and domain
• 03_evaluation_eval_data.sh
  • This script execute dcase2024_task2_evaluator.py.

Usage

1. Clone repository

Clone this repository from Github.

2. Prepare data

• Anomaly scores
  • Generate csv files anomaly_score_<machine_type>_section_<section_index>_test.csv and decision_result_<machine_type>_section_<section_index>_test.csv or anomaly_score_DCASE2024T2<machine_type>_section_<section>_test_seed<seed><tag>_Eval.csv and decision_result_DCASE2024T2<machine_type>_section_<section>_test_seed<seed><tag>_Eval.csv by using a system for the evaluation dataset. (The format information is described here.)
• Rename the directory containing the csv files to a team name
• Move the directory into ./teams/

3. Check directory structure

4. Change parameters

The parameters are defined in the script dcase2024_task2_evaluator.py as follows.

• MAX_FPR
  • The FPR threshold for pAUC : default 0.1
• --result_dir
  • The output directory : default ./teams_result/
• --teams_root_dir
  • Directory containing team results. : default ./teams/
• --dir_depth
  • What depth to search --teams_root_dir using glob. : default 2
  • If --dir_depth=2, then glob.glob(<teams_root_dir>/*/*)
• --tag
  • File name tag. : default _id(0_)
  • If using filename is DCASE2024 baseline style, change parameters as necessary.
• --seed
  • Seed used during train. : default 13711
  • If using filename is DCASE2024 baseline style, change parameters as necessary.
• --out_all
  • If this parameter is True, export supplemental data. : default False
• --additional_result_dir
  • The output additional results directory. : default ./teams_additional_result/
  • Used when --out_all==True.

5. Run script

Run the script dcase2024_task2_evaluator.py

$ python dcase2024_task2_evaluator.py

or

$ bash 03_evaluation_eval_data.sh

The script dcase2024_task2_evaluator.py calculates the AUC, pAUC, precision, recall, and F1 scores for each machine type, section, and domain and output the calculated scores into the csv files (<system_name_1>_result.csv, <system_name_2>_result.csv, ...) in --result_dir (default: ./teams_result/). If --out_all=True, each team results are then aggregated into a csv file (teams_official_score.csv, teams_official_score_paper.csv) in --additional_result_dir (default: ./teams_additional_result).

6. Check results

You can check the AUC, pAUC, precision, recall, and F1 scores in the <system_name_N>_result.csv in --result_dir. The AUC, pAUC, precision, recall, and F1 scores for each machine type, section, and domain are listed as follows:
