- Abstract: Vision-language models such as CLIP are highly useful for diverse tasks due to their shared image-text embedding space. Despite this, the image and text embeddings are often poorly aligned, affecting downstream performance. Recent work has shown that this can be attributed to an information imbalance: images contain more information than their captions describe. In this work, we propose TEVI, a framework that uses captions as a signal for what to retain from image embeddings. Specifically, we use sparse autoencoders to disentangle image embeddings and train a masking module to selectively reconstruct the embedding based on a given caption. In a controlled setup with synthetic captions, we show that TEVI is effective at preserving caption-described attributes while discarding others. By applying TEVI to CLIP models trained on natural images, we further achieve improved retrieval performance across coarse-grained short-caption (MS COCO, Flickr) and fine-grained long-caption (IIW, DOCCI) benchmarks, with stronger gains on richer captions, and improved robustness on the RoCOCO benchmark.

Visual-Language Models (VLMs) have achieved remarkable progress in image captioning, visual question answering, and visual reasoning.<n>They remain prone to vision-language misalignment, often producing overly generic or hallucinated descriptions.<n>Existing approaches address this via instruction tuning-requiring costly, large-scale annotated datasets or via complex test-time frameworks for caption refinement.<n>In this work, we revisit image-text alignment through the lens of cycle consistency.

Scene text recognition (STR) pre-training methods have achieved remarkable progress, primarily relying on synthetic datasets.
We introduce a novel method named Decoder Pre-training with only text for STR (DPTR)
DPTR treats text embeddings produced by the CLIP text encoder as pseudo visual embeddings and uses them to pre-train the decoder.

We describe a protocol to study text-to-video retrieval training with unlabeled videos.
We assume (i) no access to labels for any videos, and (ii) access to labeled images in the form of text.
We show that automatically labeling video frames with image captioning allows text-to-video retrieval training.

We propose using CLIP, a multimodal encoder trained on huge image-text pairs from web, to calculate multimodal similarity and use it as a reward function.
We also propose a simple finetuning strategy of the CLIP text encoder to improve grammar that does not require extra text annotation.
In experiments on text-to-image retrieval and FineCapEval, the proposed CLIP-guided model generates more distinctive captions than the CIDEr-optimized model.
