Keshu's Optimus Graph SSL achieves 5x fewer labels needed
Live demo shows Optimus matches GCN accuracy with minimal labels.
Keshu007 has introduced Optimus, a novel graph semi-supervised learning (SSL) method that demonstrates remarkable performance while utilizing significantly fewer labeled data points. In experiments conducted on the PathMNIST dataset, Optimus achieved an accuracy of 79.8% with only 45 labels (5 per class), which is notably higher than the Graph Convolutional Network (GCN) baseline of 77.1%. This advancement highlights the potential of semi-supervised learning to leverage minimal labeled data effectively.
The live demo available on Hugging Face Spaces allows users to experiment with the method directly, providing a user-friendly interface to set label counts and observe corresponding accuracy metrics in real-time. This eliminates the need for installations or coding, making it accessible to a broader audience. With results indicating that Optimus can match or exceed GCN performance while requiring five times fewer labels, this method could transform how researchers and practitioners approach graph-based learning tasks, significantly reducing the labeling burden in various applications.
- Optimus achieves 79.8% accuracy with just 45 labels on PathMNIST.
- Outperforms GCN's 77.1% accuracy with 5x fewer labels.
- Interactive demo on Hugging Face allows real-time accuracy testing.
