# Emotion Classifier (Happy vs. Sad)
|
| 18 |
+
|
| 19 |
+
## Model Description
|
| 20 |
+
This is a custom **Convolutional Neural Network (CNN)** built using TensorFlow and Keras. The model is designed to perform binary image classification to distinguish between "Happy" and "Sad" facial expressions.
|
| 21 |
+
|
| 22 |
+
- **Model Type:** CNN (Sequential)
|
| 23 |
+
- **Task:** Binary Image Classification
|
| 24 |
+
- **Framework:** TensorFlow/Keras
|
| 25 |
+
|
| 26 |
+
## Training Data
|
| 27 |
+
The model was trained on a localized dataset of approximately 300 images.
|
| 28 |
+
- **Preprocessing:** Images were resized to 256x256 pixels and normalized (pixel values scaled between 0 and 1).
|
| 29 |
+
- **Data Integrity:** A pre-training script was used to validate image headers and remove corrupted files.

|
| 37 |
+
During evaluation, the model achieved the following results:
|
| 38 |
+
- **Training Accuracy:** 98.9%
|
| 39 |
+
- **Validation Accuracy:** 96.9%
|
| 40 |
+
- **Precision:** 1.0 (on test batch)
|
| 41 |
+
- **Recall:** 1.0 (on test batch)

## How to Use
|
| 46 |
+
To load this model in Python:
|
| 47 |
+
|
| 48 |
+
```python
|
| 49 |
+
from tensorflow.keras.models import load_model
|
| 50 |
+
import cv2
|
| 51 |
+
import numpy as np
|
| 52 |
+
|
| 53 |
+
model = load_model('imageclassifier.h5')
|
| 54 |
+
img = cv2.imread('your_image.jpg')
|
| 55 |
+
resize = tf.image.resize(img, (256, 256))
|
| 56 |
+
prediction = model.predict(np.expand_dims(resize/255, 0))
|
| 57 |
+
|
| 58 |
+
if prediction > 0.5:
|
| 59 |
+
print('Predicted: Sad')
|
| 60 |
+
else:
|
| 61 |
+
print('Predicted: Happy')
