Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
Sound20
This is a dataset including 20 animal and instrument sounds. This dataset is constructed using Animal Sound Data and Instrument Data. Each audio is split into multiple samples, and we make sure that samples in Train, Validation, Test sets are disjoint and separated.
Data
You can find spectrograms of samples in spectrogram_data.

Usage
Loading data
You can load this dataset using Python with Numpy.
import numpy as np
x_train = np.load('spectrogram_data/train_X.npy')
y_train = np.load('spectrogram_data/train_Y.npy')Evaluate using CNNs
We conduct two experiments on this dataset using LeNet and VGG_F network structures. To run the experiments, please using the following commands.
For LeNet, use
sh scripts/run_LeNet.sh
For VGG_F, use
sh scripts/run_VFF_F.sh
Note that each script will run training and testing procedures and store the Train, Val, Test accuracy.
