• [okt 2023] Preprint: How (not) to ensemble LVLMs for VQA (arXiv) with Lisa (intern), Lluis, Mostafa, Fantine and Jasper. Abstract: In the recent work on Encyclopedic-VQA the authors examine a wide variety of models to solve their task: from vanilla LVLMs, to models including the caption as extra context, to models augmented with Lens-based retrieval of Wikipedia pages. Intuitively these models are highly complementary, which should make them ideal for ensembling. Indeed, an oracle experiment shows potential gains from 48.8% accuracy (the best single model) all the way up to 67% (best possible ensemble). So it is a trivial exercise to create an ensemble with substantial real gains. Or is it?

• [june 2023] Preprint. Encyclopedic VQA: Visual questions about detailed properties of fine-grained categories (arXiv) with Jasper, Lluis, Arushi, Felipe, Howard, Fei, André, and Vitto. Abstract: Encyclopedic-VQA is a dataset with 1M VQA triplets featuring visual questions about detailed properties of fine-grained categories and instances. This dataset poses a hard challenge for large vision+language models, PaLI achieves only 13.0% accuracy), while retrieval augmented methods perform much better.
