Unnatural language processing: How do language models handle machine-generated prompts?

no code implementations24 Oct 2023 Corentin Kervadec, Francesca Franzon, Marco Baroni

Language model prompt optimization research has shown that semantically and grammatically well-formed manually crafted prompts are routinely outperformed by automatically generated token sequences with no apparent meaning or syntactic structure, including sequences of vectors from a model's embedding space.

Cross-Domain Image Captioning with Discriminative Finetuning

1 code implementation CVPR 2023 Roberto Dessì, Michele Bevilacqua, Eleonora Gualdoni, Nathanael Carraz Rakotonirina, Francesca Franzon, Marco Baroni

However, when the model is used without further tuning to generate captions for out-of-domain datasets, our discriminatively-finetuned captioner generates descriptions that resemble human references more than those produced by the same captioner without finetuning.

Referential communication in heterogeneous communities of pre-trained visual deep networks

1 code implementation4 Feb 2023 Matéo Mahaut, Francesca Franzon, Roberto Dessì, Marco Baroni

As a first step in this direction, we systematically explore the task of \textit{referential communication} in a community of heterogeneous state-of-the-art pre-trained visual networks, showing that they can develop, in a self-supervised way, a shared protocol to refer to a target object among a set of candidates.

Communication breakdown: On the low mutual intelligibility between human and neural captioning

1 code implementation20 Oct 2022 Roberto Dessì, Eleonora Gualdoni, Francesca Franzon, Gemma Boleda, Marco Baroni

We compare the 0-shot performance of a neural caption-based image retriever when given as input either human-produced captions or captions generated by a neural captioner.
