<p class="archive__item-excerpt" itemprop="description"><p>Images in Math AI Considered harmful? Not quite. This paper demonstrates improved performance on question answering problems in math by customizing the neural network architecture to pool information from both vision and text backbones. The improvements come from a custom QF layer which includes multihead self attention layers as well as a cross attention layer (vision &amp; text). We fine tune the model using the smart-101 dataset presented in CVPR 2023.</p>
