This is a Plain English Papers summary of a research paper called Data-Efficient Multimodal Fusion on a Single GPU. If you like these kinds of analysis, you should subscribe to the AImodels.fyi newsletter or follow me on Twitter.

The paper introduces FuseMix, a multimodal augmentation scheme that learns a shared latent space between different modalities, such as images, text, and audio, by leveraging pre-trained unimodal encoders. The key advantages of FuseMix are its competitive performance compared to state-of-the-art methods and its significantly lower computational and data requirements.

Specifically, FuseMix outperforms CLIP, a prominent image-text retrieval model, on the Flickr30K text-to-image retrieval task while using approximately 600 times fewer GPU days and 80 times fewer image-text pairs during training. Additionally, the paper demonstrates how FuseMix can convert pre-trained text-to-image generative models into audio-to-image ones, showcasing its versatility.

The authors argue that pre-trained unimodal encoders, which are trained on large amounts of unimodal data, provide an effective starting point for creating multimodal models at a much lower cost compared to training from scratch on massive datasets of paired inputs.
