# CS4347_SED_GroupProject
This repo is designed for CS4347 Group Project. It is dedicated to provide a quick start for beginners who are interested in Sound Event Detection (SED). The goal of SED is to classify the events of a recording into a set of provided classes and to identify their corresponding time boundaries.

### Data preparation
The dataset can be directly downloaded from https://goo.gl/PJUVAd (for training set) and https://goo.gl/ip8JXW (for testing set). After downloading, users should prepare the data looks like:
```
dataset_root
├── training (51172 audios)
│    └── ...
├── testing (488 audios)
│    └── ...
└── metadata
     ├── testing_set.csv
     ├── groundtruth_strong_label_testing_set.csv
     ├── groundtruth_weak_label_testing_set.csv
     ├── groundtruth_weak_label_training_set.csv
     └── training_set.csv
```

### Get start with the provided code

#### 1. Install the required package
```
pip install -r requirements.txt
```

#### 2. Run runme.sh
```
sh ./runme.sh
```
runme.sh include:
* Modify the paths to your dataset and workplace.
* Select the model you want to develop.
* Pack the waveforms and targets to hdf5 files.
* Train a specific model.
* Calculate metrics on testset.
* (Optional) Inference on the evaluation dataset.
