Deep Learning

What is Deep Learning?

Deep learning is a subset of machine learning and therefore artificial intelligence. It employs artificial neural networks, with numerous intermediate layers between the input layer and the output layer, thereby forming an extensive internal structure.

The deep learning algorithm is trained with large data sets, from which rules are generated that can then be applied to other data sets. In this way, complex sets of rules can be created that do not have to be programmed by hand

Defect detection with artificial intelligence

Using artificial intelligence, the proven inspection performance of the MBJ electroluminescence tester has once again significantly improved.
A pre-trained neural network reliably detects typical defects such as micro-cracks, dark areas and soldering defects, while the pseudo defect rate is once again significantly reduced.

MBJ also provides the profound hyper parameter optimization for:

  • Best computing performance
  • Minimum processing power
  • And fastest feature extraction

No time-consuming optimization

Remarkably, the deep learning method is very robust to variations in the cell material.

  • The time-consuming and error-prone optimization of the image processing parameters is completely eliminated.
  • Only a few more sample images are required for optimization. With relatively little effort, additional defect classes can be added according to customer requirements.

 

MBJ offers image processing with neural networks for all electroluminescence inspection systems in its product range.
