Machine Learning and AI on NVH

2025-05-12
Machine learning on NVH is the application of artificial intelligence to optimize and enhance the NVH features of vehicles. It can help engineers to speed up the NVH verification process, predict the NVH effects of new designs, and leverage historical NVH data to improve vehicle development. The automotive industry is exploring the potential of machine learning on NVH, as there is a large and consistent amount of NVH data available from hundreds of vehicles tested by OEMs and big data from simulations with potential advantages to capture greater number of spatial details. Some of the machine learning techniques that are applied to NVH include, but are not limited to: Gaussian Process, Gradient Boosting Machine, Discrete Random Forest. The session of machine learning on NVH will cover the following topics: -How to create a machine learning NVH model using different algorithms.
