Towards Language Models That Can See: Computer Vision Through the LENS of Natural Language

1 code implementation28 Jun 2023 William Berrios, Gautam Mittal, Tristan Thrush, Douwe Kiela, Amanpreet Singh

We propose LENS, a modular approach for tackling computer vision problems by leveraging the power of large language models (LLMs).

Joint rotational invariance and adversarial training of a dual-stream Transformer yields state of the art Brain-Score for Area V4

1 code implementation8 Mar 2022 William Berrios, Arturo Deza

However, in this paper, we provide evidence against the unexpected trend of Vision Transformers (ViT) being not perceptually aligned with human visual representations by showing how a dual-stream Transformer, a CrossViT$~\textit{a la}$ Chen et al. (2021), under a joint rotationally-invariant and adversarial optimization procedure yields 2nd place in the aggregate Brain-Score 2022 competition(Schrimpf et al., 2020b) averaged across all visual categories, and at the time of the competition held 1st place for the highest explainable variance of area V4.
