+# DarkNetTiny
+
+## **Use case** : `Image classification`
+
+# Model description
+
+
+DarkNet is a convolutional neural network architecture that serves as the backbone for the YOLO (You Only Look Once) object detection series. It is designed for **efficient feature extraction with a focus on real-time object detection applications**.
+
+DarkNetTiny is the compact version designed for embedded deployment. It features **Leaky ReLU activations**, **batch normalization** after every convolutional layer, and uses **global average pooling** instead of fully connected layers to reduce parameter count.
+
+The straightforward stack of convolutional layers makes it easy to implement and modify, while maintaining competitive performance on edge devices.
+
+(source: https://arxiv.org/abs/1804.02767)
+
+The model is quantized to **int8** using **ONNX Runtime** and exported for efficient deployment.

+### Accuracy with Imagenet dataset
+
+Dataset details: [link](https://www.image-net.org)
+Number of classes: 1000.
+To perform the quantization, we calibrated the activations with a random subset of the training set.
+For the sake of simplicity, the accuracy reported here was estimated on the 50000 labelled images of the validation set.
