Proposes Realistic Compositional Zero-Shot Learning (RCZSL), a benchmark on re-labelled MIT-States with GAN-generated art and cartoon domains, and a dynamic visual and semantic modulator method for unseen concepts, compositions, and styles.
Problem
Compositional zero-shot learning assumes test compositions use seen attributes and objects in the same image style, but realistic test images can contain unseen concepts, compositions, and image styles simultaneously, causing domain shift.
Approach
Two dynamic modulators adapt visual features (dynamic convolution with kernel weights predicted from semantic and style statistics) and composition prototypes (attention over low-level visual features) to each input image, to mitigate domain shift from unknown factors.
Key results
- On UT-Zappos (CLIP-free), the method reaches AUC 26.6 and HM 37.7 versus SCEN's 25.2 and 32.0, improving over prior SOTA by nearly 5 points on harmonic mean and AUC.
- With CLIP ViT-L/14 backbone on UT-Zappos, AUC 39.6/HM 52.0 vs CSP's 33.0/46.6 (CSP-based comparison reported in Table 3).
- Ablation on RCZSL (art test domain) shows visual plus semantic modulators together raise HM from 19.7 to 27.5 for the photo-train setting.

Limitations
- Only evaluated on image classification; segmentation and video are left to future work.
- Re-labelled MIT-States and GAN-generated domains may contain label noise and incomplete annotations, causing failure cases.
- Visual and text encoders are kept frozen during training; CLIP-based variant only applies the semantic modulator.
