# MNIST Digit Classifier
|
| 11 |
+
|
| 12 |
+
This is a Keras/TensorFlow model trained on the MNIST dataset to classify handwritten digits (0-9).
|
| 13 |
+
|
| 14 |
+
## Model Details
|
| 15 |
+
- **Framework:** TensorFlow / Keras
|
| 16 |
+
- **Task:** Image Classification (Multi-class)
|
| 17 |
+
- **Dataset:** MNIST
|
| 18 |
+
|
| 19 |
+
## Intended Use
|
| 20 |
+
This model is intended for educational purposes to demonstrate digit classification.
|
| 21 |
+
|
| 22 |
+
## Usage
|
| 23 |
+
|
| 24 |
+
You can download and load this model in Python:
|
| 25 |
+
|
| 26 |
+
```python
|
| 27 |
+
from huggingface_hub import hf_hub_download
|
| 28 |
+
import tensorflow as tf
|
| 29 |
+
|
| 30 |
+
# Download the model file
|
| 31 |
+
model_path = hf_hub_download(repo_id="your-username/your-model-name", filename="mnist_model.keras")
|
| 32 |
+
|
| 33 |
+
# Load the model
|
| 34 |
+
model = tf.keras.models.load_model(model_path)
|
| 35 |
+
```
