With the development of Large Language Models like ChatGPT and DALL-E and the rise in reputation of generative Artificial Intelligence, producing content material like a human is not any extra a dream. Everything is now possible, together with query answering, code completion, and technology of content material from textual descriptions, in addition to the creation of pictures from each textual content and pictures. Recently, AI has been on par with human ingenuity. The well-known chatbot developed by OpenAI, known as ChatGPT, is predicated on GPT 3.5’s transformer structure and is being utilized by virtually everybody. The newest model of GPT, i.e., GPT 4, is multimodal in nature, not like the earlier model, GPT 3.5, which solely lets ChatGPT take textual inputs.
The high quality of generative content material has considerably elevated because of the event of diffusion fashions. Because of those developments, Artificial Intelligence Generative Content (AIGC) platforms, like DALLE, Stability AI, Runway, and Midjourney, have turn into more and more widespread as these methods let customers create high-quality pictures based mostly on textual content prompts supplied in pure language. Despite advances in multimodal understanding, vision-language fashions nonetheless have problem understanding generated visuals. In comparability to actual knowledge, artificial pictures show a bigger diploma of content material and model variability, making it far tougher for fashions to know them correctly.
To handle these points, a workforce of researchers has launched JourneyDB, a large-scale dataset particularly curated for multimodal visible understanding of generative pictures. JourneyDB has 4 million distinctive, high-quality generated pictures which have been created utilizing totally different textual content prompts. This dataset focuses on each content material and model interpretation and seeks to supply a whole useful resource for coaching and assessing fashions’ talents to grasp generated pictures.

The 4 duties included within the recommended benchmark are as follows.
- Prompt inversion – Prompt inversion has been used to seek out the textual content prompts that the consumer used to generate a picture. This assessments the mannequin’s comprehension of the generated pictures’ content material and model.
- Style retrieval – The workforce has targeted on model retrieval in order that the mannequin identifies and retrieves comparable generative pictures based mostly on their stylistic attributes. This assesses the mannequin’s proficiency in discerning stylistic nuances inside generative pictures.
- Image captioning – In picture captioning, the mannequin is tasked with producing descriptive captions that precisely signify the content material of the generative picture, which thus evaluates the mannequin’s functionality to grasp and categorical the visible components of the generated content material successfully in pure language.
- Visual Question Answering – Through Visual Question Answering (VQA), the mannequin gives correct solutions to questions associated to the generative picture. The mannequin is ready to comprehend the visible and model content material and present related responses based mostly on the given questions.
The workforce gathered 4,692,751 image-text immediate pairs and divided them into three units: a coaching set, a validation set, and a take a look at set. For analysis, the workforce carried out intensive experiments utilizing the benchmark dataset. The outcomes confirmed that present state-of-the-art multimodal fashions don’t carry out in addition to they do on actual datasets, however a couple of changes on the proposed dataset tremendously improved their efficiency.
