254b24cb21 feat(viz): Update plotting for STFT data visualization with color map 'jet' and added color bar 2025-05-29 20:35:35 +07:00
Rifqi D. Panuluh
d151062115 Add Working Milestone with Initial Results and Model Inference (#82)
* wip: add function to create stratified train-test split from STFT data

* feat(src): implement working function for dataset B to create ready data from STFT files stft_files and add setup.py for package configuration

* feat(notebook): Update variable names for clarity, remove unused imports, and streamline data processing. Implement data concatenation using pandas concat for efficiency. Add validation steps for Dataset B and improve model training consistency across sensors.

* fix(.gitignore): add rule to ignore egg-info directories and ensure proper formatting

* docs(README): add instructions for running stft.ipynb notebook

* feat(notebook): Add evaluation metrics and confusion matrix visualizations for model predictions on Dataset B. Remove commented-out code and integrate data preparation using create_ready_data function.
