# Bird Classifier EfficientNet-B2
|
|
|
|
|
|
|
| 15 |
|
| 16 |
+
## Model Description
|
|
|
|
|
|
|
| 17 |
|
| 18 |
+
Have you look at a bird and said "Woahh if only I know what bird that is".
|
| 19 |
+
Unless you're an avid bird spotter (or just love birds in general), it's hard to differentiate some species of birds.
|
| 20 |
+
Well you're in luck, turns out you can use a image classifier to identify bird species!
|
| 21 |
|
| 22 |
+
This model is a fine-tuned version of [google/efficientnet-b2](https://huggingface.co/google/efficientnet-b2)
|
| 23 |
+
on the [gpiosenka/100-bird-species](https://www.kaggle.com/datasets/gpiosenka/100-bird-species) dataset available on Kaggle.
|
| 24 |
+
The dataset used to train the model was taken on September 24th, 2023.
|
| 25 |
+
|
| 26 |
+
The original model itself was trained on ImageNet-1K, thus it might still have some useful features for identifying creatures like birds.
|
| 27 |
+
|
| 28 |
+
In theory, the accuracy for a random guess on this dataset is 0.0019047619 (essentially 1/525).
|
| 29 |
+
The model performed significantly well on all three sets with result being:
|
| 30 |
+
|
| 31 |
+
- **Training**: 0.999480
|
| 32 |
+
- **Validation**: 0.985904
|
| 33 |
+
- **Test**: 0.991238
|
| 34 |
+
|
| 35 |
+
## Intended Uses
|
| 36 |
+
|
| 37 |
+
You can use the raw model for image classification. See the [model hub](https://huggingface.co/models?search=efficientnet) to look for
|
| 38 |
+
fine-tuned versions on a task that interests you.
|
| 39 |
+
|
| 40 |
+
Here is an example of the model in action using a picture of a bird
|
| 41 |
+
|
| 42 |
+
```python
|
| 43 |
+
# Importing the libraries needed
|
| 44 |
+
import torch
|
| 45 |
+
import urllib.request
|
| 46 |
+
from PIL import Image
|
| 47 |
+
from transformers import EfficientNetImageProcessor, EfficientNetForImageClassification
|
| 48 |
+
|
| 49 |
+
# Determining the file URL
|
| 50 |
+
url = 'some url'
|
| 51 |
+
|
| 52 |
+
# Opening the image using PIL
|
| 53 |
+
img = Image.open(urllib.request.urlretrieve(url)[0])
|
| 54 |
+
|
| 55 |
+
# Loading the model and preprocessor from HuggingFace
|
| 56 |
+
preprocessor = EfficientNetImageProcessor.from_pretrained("dennisjooo/Birds-Classifier-EfficientNetB2")
|
| 57 |
+
model = EfficientNetForImageClassification.from_pretrained("dennisjooo/Birds-Classifier-EfficientNetB2")
|
| 58 |
+
|
| 59 |
+
# Preprocessing the input
|
| 60 |
+
inputs = preprocessor(img, return_tensors="pt")
|
| 61 |
+
|
| 62 |
+
# Running the inference
|
| 63 |
+
with torch.no_grad():
|
| 64 |
+
logits = model(**inputs).logits
|
| 65 |
+
|
| 66 |
+
# Getting the predicted label
|
| 67 |
+
predicted_label = logits.argmax(-1).item()
|
| 68 |
+
print(model.config.id2label[predicted_label])
|
| 69 |
+
```
|
| 70 |
+
|
| 71 |
+
Or alternatively you can streamline it using Huggingface's Pipeline
|
| 72 |
+
|
| 73 |
+
```python
|
| 74 |
+
# Importing the libraries needed
|
| 75 |
+
import torch
|
| 76 |
+
import urllib.request
|
| 77 |
+
from PIL import Image
|
| 78 |
+
from transformers import pipeline
|
| 79 |
+
|
| 80 |
+
# Determining the file URL
|
| 81 |
+
url = 'some url'
|
| 82 |
+
|
| 83 |
+
# Opening the image using PIL
|
| 84 |
+
img = Image.open(urllib.request.urlretrieve(url)[0])
|
| 85 |
+
|
| 86 |
+
# Loading the model and preprocessor using Pipeline
|
| 87 |
+
pipe = pipeline("image-classification", model="dennisjooo/Birds-Classifier-EfficientNetB2")
|
| 88 |
+
|
| 89 |
+
# Running the inference
|
| 90 |
+
result = pipe(img)[0]
|
| 91 |
+
|
| 92 |
+
# Printing the result label
|
| 93 |
+
print(result['label'])
|
| 94 |
+
```
|
| 95 |
+
|
| 96 |
+
## Training and Evaluation
|
| 97 |
+
|
| 98 |
+
### Data
|
| 99 |
+
|
| 100 |
+
The dataset was taken from [gpiosenka/100-bird-species](https://www.kaggle.com/datasets/gpiosenka/100-bird-species) on Kaggle.
|
| 101 |
+
It contains a set of 525 bird species, with 84,635 training images, 2,625 each for validation and test images.
|
| 102 |
+
Every image in the dataset is a 224 by 224 RGB image.
|
| 103 |
+
|
| 104 |
+
The training process used the same split provided by the author.
|
| 105 |
+
For more details, please refer to the [author's Kaggle page](https://www.kaggle.com/datasets/gpiosenka/100-bird-species).
|
| 106 |
+
|
| 107 |
+
### Training Procedure
|
| 108 |
+
|
| 109 |
+
The training was done using PyTorch on Kaggle's free P100 GPU. The process also includes the usage of Lightning and Torchmetrics libraries.
|
| 110 |
+
|
| 111 |
+
### Preprocessing
|
| 112 |
+
Each image is preprocessed according to the the orginal author's [config](https://huggingface.co/google/efficientnet-b2/blob/main/preprocessor_config.json).
|
| 113 |
+
|
| 114 |
+
The training set was also augmented using:
|
| 115 |
+
|
| 116 |
+
- Random rotation of 10 degrees with probability of 50%
|
| 117 |
+
- Random horizontal flipping with probability of 50%
|
| 118 |
+
|
| 119 |
+
### Training Hyperparameters
|
| 120 |
+
|
| 121 |
+
The following are the hyperparameters used for training:
|
| 122 |
+
|
| 123 |
+
- **Training regime:** fp32
|
| 124 |
+
- **Optimizer**: Adam with default betas
|
| 125 |
+
- **Learning rate**: 1e-3
|
| 126 |
+
- **Learning rate scheduler**: Reduce on plateau which monitors validation loss with patience of 2 and decay rate of 0.1
|
| 127 |
+
- **Batch size**: 64
|
| 128 |
+
- **Early stopping**: Monitors validation accuracy with patience of 10
|
| 129 |
+
|
| 130 |
+
