+# ProxylessNAS
+
+## **Use case** : `Image classification`
+
+# Model description
+
+
+
+ProxylessNAS enables **direct neural architecture search on target hardware**, eliminating the "proxy" task typically used in NAS. It learns specialized architectures optimized for specific devices without costly re-training.
+
+The architecture employs **direct hardware targeting** by searching directly on target hardware metrics, using **path-level binarization** as an efficient search method with binary architecture parameters. **Latency regularization** incorporates actual latency into the search objective, resulting in **hardware-specific architectures** optimized for different hardware platforms.
+
+ProxylessNAS achieves high accuracy (74.25% Top-1) with good quantization stability (0.60% drop), making it ideal for applications requiring hardware-optimized architectures with strict latency requirements.
+
+(source: https://arxiv.org/abs/1812.00332)
+
+The model is quantized to **int8** using **ONNX Runtime** and exported for efficient deployment.
