# Model Description

**Ru**ssian **D**iffusion **O**n **L**anguage **P**icture **H**yper-modality (RuDOLPH) 2.7B is a fast and light text-image-text transformer designed for a quick and easy fine-tuning setup for the solution of various tasks: from generating images by text description and image classification to visual question answering and more. This model demonstrates the power of Hyper-modality Transformers.

*(!!!) Hyper-modality means generalized multi-modal, e.g., model that consists of two multi-modal parts: text-2-image and image-2-text becomes text and image hyper-modality model*

This is a fine-tuned version of the pre-trained RuDOLPH 2.7B model.

The model was prepared as a baseline for AI Journey 2022 (AIJ2) fine-tuned using 6 tasks:

* Text QA – SberQUaD dataset.
* Math QA – DeepMind Mathematics Dataset.
* Captioning – COCO dataset.
* VQA – COCO dataset with prepared question set.
* Generation – COCO dataset.
* Text-in-the-wild – synthesized data.

# Sparse Attention Mask

The primary proposed method is to modify the sparse transformer's attention mask to better control multi-modalities and up to the next level with "hyper-modality". It allows us to calculate the transitions of modalities in both directions, unlike another similar work DALL-E Transformer, which used only one direction, "text to image". The proposed "image to right text" direction is achieved by extension sparse attention mask to the right for auto-repressively text generation with both image and left text condition.
