# Galaxy10 SDSS Dataset CNN TF Model
|
| 15 |
+
|
| 16 |
+
This model contains a Convolutional Neural Network (CNN) ensemble model trained on the Galaxy10 SDSS Dataset available in the astroNN library.
|
| 17 |
+
|
| 18 |
+
## Dataset
|
| 19 |
+
The Galaxy10 SDSS Dataset is a collection of astronomical images categorized into 10 classes of galaxies.
|
| 20 |
+
|
| 21 |
+
To access the dataset:
|
| 22 |
+
- Visit the [astroNN Galaxy10 SDSS Documentation](https://astronn.readthedocs.io/en/stable/galaxy10sdss.html)
|
| 23 |
+
|
| 24 |
+
## Models Used
|
| 25 |
+
The ensemble model comprises the following pre-trained CNN architectures:
|
| 26 |
+
- AlexNet
|
| 27 |
+
- DenseNet121
|
| 28 |
+
- ResNet50
|
| 29 |
+
- EfficientNet-V2-M
|
| 30 |
+
|
| 31 |
+
## Ensemble Learning Technique
|
| 32 |
+
The ensemble model employs Mean Voting to aggregate predictions from individual models. This technique combines the output probabilities or predictions from each model and calculates the mean for final classification.
|
| 33 |
+
|
| 34 |
+
## Results
|
| 35 |
+
After training and evaluation on the Galaxy10 SDSS Dataset, using the test dataset, the ensemble model achieved the following metrics:
|
| 36 |
+
- Accuracy: 0.8653
|
| 37 |
+
- Precision: 0.8597
|
| 38 |
+
- Recall: 0.8602
|
| 39 |
+
- F1-score: 0.8653
|
| 40 |
+
- Loss: 0.8292
|
| 41 |
+
|
| 42 |
+
|
| 43 |
+
## Training
|
| 44 |
+
The models were trained using PyTorch, leveraging transfer learning for some architectures and training from scratch for others. The ensemble learning technique was applied post-training using the mean voting strategy.
|
| 45 |
+
|
| 46 |
+
## Requirements
|
| 47 |
+
- PyTorch v2.1.0
|
| 48 |
+
- CUDA v11.8 (cu118)
|
| 49 |
+
|
| 50 |
+
