ML/AI Methods for Process Monitoring – Focus on Laser Materials Processing
Machine learning and artificial intelligence are increasingly important tools for industrial process monitoring. Yet for early-career engineers and scientists, the gap between ML/AI theory and practical application can make it difficult to identify where to begin and how these methods can be applied effectively.
Demystifying: Machine Learning – presented by Optica – aims to bridge the gap through an accessible, application-focused introduction to ML/AI, with particular emphasis on process monitoring and laser materials processing.
Program
This three-hour program introduces the motivation and fundamentals of ML/AI before moving into examples of ML/AI for process monitoring, with a focus on laser materials processing. Drawing on approximately 30 years of experience in ML/AI, the instructor will share practical lessons, common considerations, and guidance for getting started. The program is discussion- and example-based; no hands-on coding component is included.
