Usage

Installation

pip install tensorflow keras

Load and Use the Model

import tensorflow as tf
from tensorflow import keras
from PIL import Image
import numpy as np

# Load the model
model = keras.models.load_model('best.keras')

# Prepare image
image = Image.open('path/to/potato_leaf.jpg')
image = image.resize((224, 224))
image_array = np.array(image) / 255.0
image_array = np.expand_dims(image_array, axis=0)

# Make prediction
predictions = model.predict(image_array)
class_names = ['Bacteria', 'Fungi', 'Healthy', 'Nematode', 'Pest', 'Phytophthora', 'Virus']
predicted_class = class_names[np.argmax(predictions)]
confidence = np.max(predictions)

print(f"Predicted Disease: {predicted_class}")
print(f"Confidence: {confidence:.2%}")

Intended Use

This model is intended for:

• Primary Use: Classification of potato leaf diseases in agricultural applications
• Supported Use Cases:
  • Automated disease detection systems
  • Agricultural advisory systems
  • Precision farming applications
  • Research and baseline comparisons

Limitations

• Dataset Scope: Trained exclusively on Mendeley dataset; performance may vary on other potato disease datasets
• Class Imbalance: Some classes (Nematode: 14 samples) have limited training data
• Environmental Factors: Model trained on field conditions; controlled environment images may perform differently
• Image Quality: Requires clear leaf images; heavily obscured or blurry images may reduce accuracy
• Biological Variation: Limited to potato plant diseases; not suitable for other crop diseases
