# RUDOLPH-350M (Medium)
RUDOLPH: One Hyper-Modal Transformer can be creative as DALL-E and smart as CLIP
Model was trained by [Sber AI](https://github.com/sberbank-ai) and [SberDevices](https://sberdevices.ru/) teams.
* Task: `text2image generation`; `self reranking`; `text ranking`; `image ranking`; `image2text generation`; `zero-shot image classification`, `text2text generation`;
* Language: `Russian`
* Type: `encoder-decoder`
* Num Parameters: `350M`
* Training Data Volume: `156 million text-image pairs`
# Model Description
**RU**ssian **D**ecoder **O**n **L**anguage **P**icture **H**yper-tasking (**RUDOLPH**) **350M** is a fast and light text-image-text transformer (350M GPT-3) designed for a quick and easy fine-tuning for a range of tasks: from generating images by text description and image classification to visual question answering and more. This model demonstrates the power of Hyper-tasking Transformers.
*Hyper-tasking means generalized multi-tasking, e.g., the model that can solve almost all tasks within supported modalities (two modalities in case of RUDOLPH: images and Russian texts).*
# Details of architecture
### Parameters
The maximum sequence length that this model may be used with depends on the modality and stands for 384 - 576 - 128 for the left text tokens, image tokens, and right text tokens, respectively.
RUDOLPH 2.7B is a Transformer-based decoder model with the following parameters:
* num\_layers (24) — Number of hidden layers in the Transformer decoder.
* hidden\_size (1024) — Dimensionality of the hidden layers.
* num\_attention\_heads (16) — Number of attention heads for each attention layer.
# 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 image condition without attention to left text.
