Zero-Shot Node Classification through Generative Prompt Tuning
The Zero-shot Prompt Tuning (ZPT) framework addresses the critical challenge of classifying nodes in text-attributed graphs (TAGs) without any labeled data. At its heart is the Universal Bimodal Conditional Generator (UBCG), which learns to create synthetic, class-specific examples for prompt tuning, sidestepping the need for manual labels or error-prone pseudo-labels. This enables robust and scalable zero-shot classification across diverse enterprise data.

Benchmarking ZPT Against Leading Models
Our Zero-shot Prompt Tuning (ZPT) approach demonstrates superior performance against state-of-the-art baselines across multiple benchmark datasets. By integrating bimodal synthetic sample generation and continuous prompt tuning, ZPT significantly improves accuracy and Macro F1 scores, crucial for real-world, often imbalanced, enterprise datasets.
| Method | Cora Acc | Cora Macro F1 | Industrial Acc | Industrial Macro F1 |
|---|---|---|---|---|
| ZPT + Context (Ours) | 68.15% | 62.26% | 86.86% | 81.88% |
| Hound + d | 69.21% | 61.41% | 81.99% | 73.84% |
| G2P2 + d | 65.28% | 60.20% | 77.43% | 70.32% |

Ensuring Stable Performance Across Enterprise Data
ZPT's underlying architecture, particularly the UBCG, is designed for technical robustness and adaptability. Extensive ablation studies confirm the benefits of bimodal synthetic generation and the effectiveness of continuous prompt tuning over traditional discrete methods. The model also shows strong insensitivity to key hyperparameters like latent dimension and the number of synthetic samples, ensuring stable performance in diverse enterprise environments.
