• Abstract summary: ASPIRE (Language-guided Data Augmentation for SPurIous correlation REmoval) is a solution for supplementing the training dataset with images without spurious features. It can generate non-spurious images without requiring any group labeling or existing non-spurious images in the training set. It improves the worst-group classification accuracy of prior methods by 1% - 38%.

• Abstract: Neural image classifiers can often learn to make predictions by overly relying on non-predictive features that are spuriously correlated with the class labels in the training data. This leads to poor performance in real-world atypical scenarios where such features are absent. This paper presents ASPIRE (Language-guided Data Augmentation for SPurIous correlation REmoval), a simple yet effective solution for supplementing the training dataset with images without spurious features, for robust learning against spurious correlations via better generalization. ASPIRE, guided by language at various steps, can generate non-spurious images without requiring any group labeling or existing non-spurious images in the training set. Precisely, we employ LLMs to first extract foreground and background features from textual descriptions of an image, followed by advanced language-guided image editing to discover the features that are spuriously correlated with the class label. Finally, we personalize a text-to-image generation model using the edited images to generate diverse in-domain images without spurious features. ASPIRE is complementary to all prior robust training methods in literature, and we demonstrate its effectiveness across 4 datasets and 9 baselines and show that ASPIRE improves the worst-group classification accuracy of prior methods by 1% - 38%. We also contribute a novel test set for the challenging Hard ImageNet dataset.

  Previous works leverage the CLIP's cross-modal association ability for image captioning, relying solely on textual information under unsupervised settings. This paper proposes a novel method to address these issues by incorporating synthetic image-text pairs. A pre-trained text-to-image model is deployed to obtain images that correspond to textual data, and the pseudo features of generated images are optimized toward the real ones in the CLIP embedding space.

  We present a novel algorithm that incorporates human knowledge on image-text alignment to guide filtering vast corpus of web-crawled image-text datasets. We collect a diverse image-text dataset where each image is associated with multiple captions from various sources. We train a reward model on these human-preference annotations to internalize the nuanced human understanding of image-text alignment.

  Contrastive Language-Image Pre-training (CLIP) has significantly boosted the performance of various vision-language tasks. The presence of intrinsic noise and unmatched image-text pairs in web data can potentially affect the performance of representation learning. We propose an Adaptive Language-Image Pre-training (ALIP), a bi-path model that integrates supervision from both raw text and synthetic caption.

  ALIA (Automated Language-guided Image Augmentation) is a method which utilizes large vision and language models to automatically generate natural language descriptions of a dataset's domains. To maintain data integrity, a model trained on the original dataset filters out minimal image edits and those which corrupt class-relevant information. We show that ALIA is able to surpasses traditional data augmentation and text-to-image generated data on fine-grained classification tasks.
