The Animals with Attributes dataset is currently suspended. Its images are not available anymore because of copyright restrictions. Please use the drop-in replacement, Animals with Attributes 2.

This dataset provides a plattform to benchmark transfer-learning algorithms, in particular attribute base classification [1]. It consists of 30475 images of 50 animals classes with six pre-extracted feature representations for each image. The animals classes are aligned with Osherson's classical class/attribute matrix [2,3], thereby providing 85 numeric attribute values for each class. Using the shared attributes, it is possible to transfer information between different classes.

Attribute based classification and the data is described in:

The class/attribute matrix was originally created by:

[2] D. N. Osherson, J. Stern, O. Wilkie, M. Stob, and E. E. Smith. "Default probability". Cognitive Science, 15(2), 1991.

Version 1.0, May 13th 2009

Because the dataset is rather large, the download is split into separate archives:

Base package (1M) including the class/attribute table:AwA-base.tar.bz2 (everybody needs this)

Color Histogram features (124M): AwA-features-cq.tar.bz2

Local Self-Similarity features (30M): AwA-features-lss.tar.bz2

PyramidHOG (PHOG) features (28M): AwA-features-phog.tar.bz2

SIFT features (44M): AwA-features-sift.tar.bz2

colorSIFT features (44M): AwA-features-rgsift.tar.bz2

SURF features (49M): AwA-features-surf.tar.bz2

Source code (30K) illustrating DAP and IAP methods: AwA-code.tar.bz2
Addendum: new attributes.py script that work with recent versions of Shogun
