+# Model Card for focalnet_b_lrf_intermediate-eu-common
+
+A FocalNet image classification model. The model follows a two-stage training process: first undergoing intermediate training on a large-scale dataset containing diverse bird species from around the world, then fine-tuned specifically on the `eu-common` dataset (all the relevant bird species found in the Arabian peninsula inc. rarities).
+
+The species list is derived from data available at <https://avibase.bsc-eoc.org/checklist.jsp?region=ARA>.
+

+
+## Model Usage
+
+### Image Classification
+
+```python
+import birder
+from birder.inference.classification import infer_image
+
+(net, model_info) = birder.load_pretrained_model("focalnet_b_lrf_intermediate-eu-common", inference=True)
+
+# Get the image size the model was trained on
+size = birder.get_size_from_signature(model_info.signature)
+
+# Create an inference transform
+transform = birder.classification_transform(size, model_info.rgb_stats)
+
+image = "path/to/image.jpeg"  # or a PIL image, must be loaded in RGB format
+(out, _) = infer_image(net, image, transform)
+# out is a NumPy array with shape of (1, 707), representing class probabilities.
+```
+
+### Image Embeddings
+
+```python
+import birder
+from birder.inference.classification import infer_image
+
+(net, model_info) = birder.load_pretrained_model("focalnet_b_lrf_intermediate-eu-common", inference=True)
+
+# Get the image size the model was trained on
+size = birder.get_size_from_signature(model_info.signature)
+
+# Create an inference transform
+transform = birder.classification_transform(size, model_info.rgb_stats)
+
+image = "path/to/image.jpeg"  # or a PIL image
+(out, embedding) = infer_image(net, image, transform, return_embedding=True)
+# embedding is a NumPy array with shape of (1, 1024)
+```
+
+### Detection Feature Map
+
+```python
+from PIL import Image
+import birder
+
+(net, model_info) = birder.load_pretrained_model("focalnet_b_lrf_intermediate-eu-common", inference=True)
+
+# Get the image size the model was trained on
+size = birder.get_size_from_signature(model_info.signature)
+
+# Create an inference transform
+transform = birder.classification_transform(size, model_info.rgb_stats)
+
+image = Image.open("path/to/image.jpeg")
+features = net.detection_features(transform(image).unsqueeze(0))
+# features is a dict (stage name -> torch.Tensor)
+print([(k, v.size()) for k, v in features.items()])
+# Output example:
+# [('stage1', torch.Size([1, 128, 96, 96])),
+#  ('stage2', torch.Size([1, 256, 48, 48])),
+#  ('stage3', torch.Size([1, 512, 24, 24])),
+#  ('stage4', torch.Size([1, 1024, 12, 12]))]
