🌱 Plant Disease Classification

---

📌 Introduction

This project leverages the power of EfficientNet, a state-of-the-art deep learning model, to help farmers and gardeners quickly and accurately identify plant diseases using images of plant leaves. Upon detecting a disease, the application provides detailed information, including the disease's name, cause, and symptoms.

⚡ EfficientNet: Why It Matters for Plant Disease Detection

EfficientNet is a convolutional neural network (CNN) designed to balance accuracy and efficiency. Unlike traditional models that scale only in width, depth, or resolution, EfficientNet scales all three dimensions simultaneously, leading to better performance with fewer computations.

🏆 Why EfficientNet for Plant Disease Classification?

✅ Higher Accuracy – Outperforms ResNet, MobileNet, and Inception models.
✅ Fewer Parameters – Uses 5x fewer parameters than ResNet-50 while achieving higher accuracy.
✅ Optimized for Mobile & Edge AI – Enables deployment on smartphones, drones, and Raspberry Pi.
✅ Faster Inference – Runs efficiently in real-time agricultural applications.

🔬 EfficientNet vs. Traditional Models

Model	Parameters	Accuracy (ImageNet)	FLOPs (B)
ResNet-50	25.6M	76.6%	4.1
MobileNetV2	3.4M	72.0%	0.3
EfficientNet-B0	5.3M	77.1%	0.4
EfficientNet-B7	66M	84.4%	37.0

📊 Key Takeaways:

• EfficientNet-B0 achieves similar accuracy to ResNet-50 but with 5x fewer parameters.
• EfficientNet-B7 outperforms most CNN architectures with 84.4% top-1 accuracy.
• Lower FLOPs (floating-point operations) mean faster inference on low-power devices.

📜 EfficientNet Architecture

EfficientNet scales a model in three dimensions:
1️⃣ Depth – More layers for complex pattern recognition.
2️⃣ Width – Wider layers to retain fine-grained details.
3️⃣ Resolution – Larger input size to detect subtle disease features.

By combining these factors, EfficientNet achieves higher accuracy while using fewer resources.

🌍 Real-World Applications

🚜 Smartphone Apps – Farmers can use mobile apps to detect diseases instantly.
🌱 IoT & Edge AI – EfficientNet models can run on Raspberry Pi & Jetson Nano.
☁️ Cloud-Based APIs – Agricultural platforms can integrate real-time plant disease detection.
📡 Drone & Smart Camera Systems – Automate plant health monitoring in large-scale farms.

🏋️‍♂️ Training the Model

📥 Download Dataset

Download the dataset manually: Kaggle Dataset

Or use Kaggle CLI:

kaggle datasets download -d nguyenchitinh/plantdisease-with-20-plant

🚀 Train the Model

python train_multiple_model.py --epoch 100 --batch_size 32 --root_dir ./Datasets --img_size 224 --export_dir ./SavedModels --h5_dir ./Models

💾 After training, model weights will be saved in:

• ./Models/ → Trained .h5 model weights.
• ./SavedModels/ → TensorFlow SavedModel format.

📊 Evaluate the Model

python evaluate.py --root_dir ./Datasets --h5_dir ./Models

🔄 Convert Model to TFLite

python convert_tflite.py

---

🌐 Server

Ensure that all TFLite models are copied to:

server/ModelLight/

▶️ Run the Server

cd server
uvicorn app.main:app --host 127.0.0.1 --port 5000

✅ API will be accessible at: http://127.0.0.1:5000

🐳 Run with Docker

docker compose up

---

🖥️ Client

Move to the client directory:

cd client

▶️ Run the Client

npm start

🔧 Configure Environment Variables

Create a .env file in the client/ folder and add:

REACT_APP_API_URL=http://127.0.0.1:5000
