Introduction
CoPrompt is a cutting-edge AI tool designed to enhance the performance of vision-language models in various downstream tasks while maintaining strong zero-shot generalization capabilities. Developed by Shuvendu Roy and Ali Etemad, this tool introduces a novel fine-tuning method that enforces consistency constraints, utilizes input perturbations, and combines prompting and adapter tuning. The platform allows teams to iterate prompts, improve outcomes, and learn from each other's input, making it an invaluable asset for collaborative projects.
background
CoPrompt was developed to address the challenge of maintaining the generalization capability of large foundation models while fine-tuning them on specific downstream tasks. The tool has been rigorously tested and proven to outperform existing methods in a range of evaluation suites, including base-to-novel generalization, domain generalization, and cross-dataset evaluation.
Features of CoPrompt
Consistency Constraint
CoPrompt enforces a consistency constraint on both the language and image branches between the trainable and pre-trained models, ensuring the embeddings produced are not significantly different from those generated by the pre-trained model.
Input Perturbations
On the language branch, CoPrompt uses a pre-trained large language model (LLM) to generate more descriptive sentences, while on the image branch, it applies augmentations to generate two perturbed images for further regularization.
Prompting and Adapter Tuning
CoPrompt combines the two dominant paradigms of tuning, prompting and adapters, to tune more parameters and improve performance on new tasks while maintaining the consistency constraint to avoid overfitting.
Cross-Dataset Evaluation
CoPrompt demonstrates strong performance in cross-dataset evaluation, showing improvements on 8 out of 10 datasets with an average accuracy of 67.0%, which is 0.70% higher than the previous state-of-the-art, MaPLe.
Domain Generalization
CoPrompt shows strong domain generalization by outperforming MaPLe on all datasets except for ImageNet-A, achieving a new state-of-the-art average accuracy of 60.43%.
