Study Notes

Introduction to Classification in Agricultural Technology

Objective: Develop an efficient classification system to foster innovation in agricultural technology.
Convolutional Neural Networks (CNNs) effectively recognize digital images, useful for various applications like facial recognition and pattern identification.

Various models derived from CNN, specifically ResNet50 and MobileNetV2, are frequently compared based on accuracy and processing speed.
Previous studies have classified crops and identified medicinal plants using the ResNet50 model, achieving high accuracy rates.
ResNet50 achieved a validation accuracy of 98.89% in detecting rotten fruit, with a rapid classification speed of about 0.2 seconds per image.
MobileNetV2-UNET model has been used to segment various plant leaves, with an accuracy of 96.38% in complex backgrounds.

Performance of Different Models

ResNet50 demonstrates superior performance in some cases, reaching up to 93.5% accuracy with transfer learning.
MobileNetV2, while effective, has a higher model complexity and longer training time compared to its predecessor.
A hybrid model, Plant Species Detection Stacking Ensemble Deep Learning Model, achieved 99.84% accuracy for plant classification.

ResNet50 Model Architecture

Introduced by Microsoft Research in 2015, ResNet50 won the ImageNet image recognition competition.
Comprised of residual blocks that utilize shortcut connections to mitigate issues in deep networks.
The architecture includes multiple convolutional layers with identity and convolutional blocks using varying filter sizes (64, 128, and 256).
