## Dataset Details

|
91 |
### Dataset Description
|
92 |
|
93 |
+
This dataset contains images for a binary classification task designed to distinguish Bo, Barack Obama's Portuguese Water Dog, from other pets (cats and dogs). The dataset was created to explore transfer learning techniques using a pre-trained VGG16 model. Bo was the Obama family's pet during their time in the White House, and this dataset simulates a computer vision system that the Secret Service might have used to automatically recognize him.
|
|
|
94 |
|
95 |
+
The dataset includes both original images and augmented versions created through various transformations including affine transforms, elastic deformations, perspective changes, and color adjustments to improve model generalization.

### Out-of-Scope Use
|
121 |
|
122 |

This dataset should not be used for:
|
123 |
+
- **Production pet identification systems**: The dataset is too small and specific for robust real-world applications
|
124 |
+
- **General dog breed classification**: Limited to distinguishing one specific dog from other pets
|
125 |
+
- **Commercial applications**: Dataset size and scope are insufficient for commercial deployment
|
126 |
+
- **Sensitive security applications**: This is a demonstration dataset, not suitable for actual security systems
|
127 |
|
128 |
## Dataset Structure

|
151 |
|
152 |
## Dataset Creation
|
153 |
|
154 |
### Curation Rationale
|
155 |
|
156 |
+
This dataset was created as an educational tool to demonstrate:
|
157 |
+
1. **Transfer Learning**: How to adapt a pre-trained model (VGG16) for a new classification task
|
158 |
+
2. **Binary Classification**: Implementing a specific classification problem with practical relevance
|
159 |
+
3. **Data Augmentation**: Techniques to improve model generalization with limited data
|
160 |
+
4. **FiftyOne Integration**: Dataset management, visualization, and evaluation workflows
|
161 |
+
5. **Model Evaluation**: Comprehensive assessment including confusion matrices and classification reports
|
162 |
|
163 |
### Source Data
|
164 |
|
|
|
|
|
165 |
#### Data Collection and Processing
|
166 |
|
167 |
+
The source data consists of:
|
168 |
+
- **Bo Images**: Photographs of Bo, Barack Obama's Portuguese Water Dog, a Portuguese Water Dog breed
|
169 |
+
- **Other Pet Images**: Collection of cats and dogs labeled as `not_bo`
|
170 |
|
171 |
+
Processing steps included:
|
172 |
+
1. **Image standardization**: All images converted to RGB format
|
173 |
+
2. **Augmentation**: Training images enhanced with geometric and photometric transformations
|
174 |
+
3. **Normalization**: ImageNet mean and standard deviation applied for VGG16 compatibility
|
175 |
+
4. **Quality control**: Manual verification of labels and image quality
|
176 |
|
177 |
#### Who are the source data producers?
|
178 |
|
179 |
+
The source data appears to be curated from publicly available images, with Bo's images likely sourced from official White House photography and news media coverage during the Obama administration.
|
|
|
|
|
|
|
|
|
180 |
|
181 |
+
### Annotations
|
182 |
|
183 |
#### Annotation process
|
184 |
|
185 |
+
Images were manually labeled into two categories:
|
186 |
+
- `bo`: Images containing Bo, the Portuguese Water Dog
|
187 |
+
- `not_bo`: Images containing other pets (cats and various dog breeds)
|
188 |
|
189 |
+
The annotation process focused on creating a balanced binary classification task suitable for transfer learning demonstrations.
|
190 |
|
191 |
#### Who are the annotators?
|
192 |
|
193 |
+
Annotations were created as part of the educational project development, with manual labeling to ensure accuracy for the binary classification task.
|
194 |
|
195 |
+
## Technical Implementation
|
196 |
|
197 |
+
### Model Architecture
|
198 |
|
199 |
+
- **Base Model**: VGG16 pre-trained on ImageNet
|
200 |
+
- **Modifications**:
|
201 |
+
- Frozen convolutional layers (feature extraction)
|
202 |
+
- Custom classifier: Linear(25088 → 4096) → ReLU → Linear(4096 → 1)
|
203 |
+
- **Loss Function**: Binary Cross Entropy with Logits
|
204 |
+
- **Optimizer**: Adam (lr=0.003, betas=(0.9, 0.999))
|
205 |
+
- **Training Epochs**: 10 epochs with early stopping
|
206 |
|
207 |
+
### Performance Metrics
|
208 |
|
209 |
+
The model evaluation includes:
|
210 |
+
- **Loss tracking**: Training and validation loss curves
|
211 |
+
- **Classification report**: Precision, recall, F1-score for both classes
|
212 |
+
- **Confusion matrix**: Visual representation of classification performance
|
213 |
+
- **Confidence scores**: Probability estimates for each prediction
|
214 |
|
215 |
+
## Bias, Risks, and Limitations
|
|
|
|
|
216 |
|
217 |
+
### Technical Limitations
|
218 |
|
219 |
+
- **Small dataset size**: 169 samples may not capture full variability
|
220 |
+
- **Limited breed diversity**: Focus on one specific dog vs. general "other pets"
|
221 |
+
- **Domain specificity**: Trained specifically for Bo recognition, not generalizable to other Portuguese Water Dogs
|
222 |
+
- **Image quality dependency**: Performance may vary with different lighting, angles, or image quality
|
223 |
|
224 |
+
### Potential Biases
|
225 |
|
226 |
+
- **Breed bias**: Model may learn Portuguese Water Dog features rather than Bo-specific characteristics
|
227 |
+
- **Environmental bias**: Training images may reflect specific environments or photography conditions
|
228 |
+
- **Size bias**: Limited sample size may not represent full range of poses, ages, or conditions
|
229 |
|
230 |
+
### Recommendations
|
231 |
|
232 |
+
Users should be aware that:
|
233 |
+
1. **This is a demonstration dataset**: Not suitable for production applications
|
234 |
+
2. **Limited generalization**: Results may not transfer to other similar classification tasks
|
235 |
+
3. **Educational focus**: Primary value is in learning transfer learning concepts
|
236 |
+
4. **Expansion needed**: Real-world applications would require significantly more diverse data
|
