Knowm Datasets HJA Birdsong

raw data

How to Get the Data

1. Manually download the database files that have been uploaded to Knowm's Google Drive account here.
2. Manually copy the DB_HJA_BIRDSONG.* files into the /usr/local/Datasets folder. There should be four files.

How to Generate Data

1. Download raw data from here: http://web.engr.oregonstate.edu/~briggsf/kdd2012datasets/hja_birdsong/
2. put all files (hierarchy.zip, test-remapped and train-remapped) in raw folder in project root
3. Run DownloadWavFiles.java and RawData2DB.java.
4. The database containing the data will appear in db.
5. Manually copy the DB_HJA_BIRDSONG.* files into some folder, which you will point to later in an app using the data such as /usr/local/Datasets/. There should be four files.

How to Use the Data in You App

1. Put the desired jar on the classpath of your application. This will give you access to the DAO and Bean classes.

2. Just call init on the DAO class you are using, passing it the path to the database files that you downloaded or generated above. When finished with the data, call release. The following example is for the BreastCancer dataset. For more examples see the datasets-samples module.

   try { BreastCancerDAO.init("/usr/local/Datasets/"); // setup data BreastCancerDemo demo = new BreastCancerDemo(); demo.go(); } catch (Exception e) { e.printStackTrace(); } finally { BreastCancerDAO.release(); // release data resources }

Birdsong Spectrograph Viewer

See: org.knowm.datasets.samples.HJABirdsongSpectrogramViewer. Make sure you've placed the generated/downloaded DB data at the location specified at the line: HJABirdsongDAO.init("/usr/local/Datasets/"); // setup data.
