BLIP - Math

Our model is fine-tuned on a mathematical multi-modal dataset, and it comprises two output heads: text generation and scoring. We provide the weight file for the text generation part of the model 'pytorch_model.bin.'

You will need 4 input sources, including two text inputs and two image inputs: 'problem_body,' 'student_response,' 'question_image,' and 'student_image.'

To perform conditional text generation:

Concatenating the text in the following manner: text = 'problem:' + ' ' + [problem_body] + ' ' + 'student:' + [student_response] + ' ' + 'response:'
Concatenating [question_image] and [student_image] vertically while keeping [question_image] on top and selecting the larger of the two image sizes.

For all other usage, follow the same procedures as with the BLIP model.

If you have any further questions or need assistance with specific code or implementation details, please feel free to ask.

TL;DR

Authors from the paper write in the abstract:

Vision-Language Pre-training (VLP) has advanced the performance for many vision-language tasks. However, most existing pre-trained models only excel in either understanding-based tasks or generation-based tasks. Furthermore, performance improvement has been largely achieved by scaling up the dataset with noisy image-text pairs collected from the web, which is a suboptimal source of supervision. In this paper, we propose BLIP, a new VLP framework which transfers flexibly to both vision-language understanding and generation tasks. BLIP effectively utilizes the noisy web data by bootstrapping the captions, where a captioner generates synthetic captions and a filter removes the noisy ones. We achieve state-of-the-art results on a wide range of vision-language tasks, such as image-text retrieval (+2.7% in average recall@1), image captioning (+2.8% in CIDEr), and VQA (+1.6% in VQA score). BLIP also demonstrates strong generalization ability when directly transferred to videolanguage tasks in a zero-shot manner. Code, models, and datasets are released.
