Applying AI to ensure the integrity of conveyor belts: The Path of a Machine Learning Engineer

In the world of industrial automation, the integrity of conveyor belts is crucial to ensure smooth and efficient operation. As a machine learning engineer, I started a project to develop and train a model aimed at detecting conveyor belt damage. Here I share my path and the technical difficulties associated with the implementation of this project.

The main goal of this project was to create a reliable and efficient model capable of accurately detecting damage on conveyor belts. Using the YOLOv8 (You Only Look Once) framework, I started designing and training a model that could identify both "good" and "bad" conveyor belt states.

Data preparation: To begin with, I have collected an extensive data set containing images of conveyor belts in various states. The dataset has been carefully labeled to distinguish between "good" and "bad" instances. This markup process was important for effective model training.

Model Training: Using the YOLOv8 framework, I started the learning process using the following key parameters:

  • Model: yolov8n.pt
  • Data: Custom dataset (data.yaml)
  • Epochs: 50
  • Batch size: 16
  • Image size: 640x640 pixels

During the training, the architecture of the model was adjusted to optimize performance. The key components of the model included convolutional layers, C2f blocks, and SPPF modules. The learning process took 50 epochs, resulting in a well-optimized model with 225 layers and approximately 3 million parameters.

After careful training and validation, the model showed impressive performance indicators.:

  • Overall Precision: 0.888
  • Total Completeness (Recall): 0.927
  • mAP50 (Average accuracy): 0.932
  • mAP50-95: 0.812

For specific classes:

  • "Bad" instances: Accuracy: 0.797, Completeness: 0.866, mAP50: 0.876, mAP50-95: 0.668
  • "Good" instances: Accuracy: 0.979, Completeness: 0.988, mAP50: 0.987, mAP50-95: 0.955

The results highlight the model's high accuracy in detecting both damaged and undamaged conveyor belts, making it a reliable tool for industrial applications.

The success of this project highlights the potential of AI in industrial automation. There are many exciting areas for research in the future, including real-time damage detection, integration with existing monitoring systems, and further improvements to the model to increase its reliability.

As a machine learning engineer, I am pleased to contribute to the development of AI-based solutions that improve operational efficiency and security. This project not only demonstrates the power of machine learning, but also shows its practical application in solving real-world problems.
