This is the original PyTorch implementation of the paper Deep Generative Clustering with Multimodal Diffusion Variational Autoencoders. presented as poster at ICLR 2024.

We introduce a variation of the CUB Image-Captions dataset [1], based on the Caltech-UCSD Birds (CUB) dataset. To do so, we group sub-species of birds in the original dataset in eight single species. As a result we obtain a challenging realistic multimodal clustering dataset. Below is an example for three datapoints (each corresponding to a different sub-species) that are grouped under the same species.

The CUBICC dataset consists of 13150 image-captions paired samples from 22 subspecies, grouped into 8 species:

Blackbird, Gull, Jay, Oriole, Tanager, Tern, Warbler, Wren.

To download the CUBICC dataset run
