Optimization of reliability and speed of the end-of-line quality inspection of electric motors using machine learning

Jernej Mlinarič, Boštjan Pregelj, Pavle Boškoski, Gregor Dolanc, Janko Petrovčič

Izvirni znanstveni članek

Oznake: quality inspection;fault detection;machine learning;

Consistently maintaining high-end product quality in the production process is challenging. End-quality inspection must be highly sensitive to detect even minimal deviations, while being fast and accurate. However, quality inspection systems often face calibration intricacies, are time-consuming, an ...

ǂA ǂtransfer learning approach to machine learning-based end-of-line quality inspection

Jernej Mlinarič, Boštjan Pregelj, Pavle Boškoski, Janko Petrovčič, Gregor Dolanc

Izvirni znanstveni članek

Oznake: zaznavanje napak;fault detection;transfer learning;random forest;

Transfer learning is a powerful machine learning technique for accelerating the learning process of a new classification task by using knowledge from an existing and related classification task that has already been trained. This technique addresses situations where the necessary training and test d ...
