Hands-on Workshop on Correlation Modelling in Data Mining for Intelligent Condition Monitoring System

Date: 13 May 2010 - 13 May 2010

Venue: Training Room 2, Level 3, SIMTech Tower Block, 71 Nanyang Drive


SIMTech is organising a hands-on workshop on correlation modelling in data mining for intelligent condition monitoring with emphasis on statistical correlation methods and neural network learning techniques. The objective of the workshop is to introduce the necessary skills in analysing data for prediction of machinery health condition and in-situ product quality monitoring.

In this workshop, participants will learn how to establish correlation models for machine/component health condition analysis and remaining useful life prediction to ensure high product quality. This workshop includes an introduction of statistical regression modeling and basics of neural networks with assessment on correlation modeling. Practical hands-on sessions on the MatLab software will be conducted to guide participants build up correlation models using multiple regression method and back-propagation neural networks. The sessions will enable participants to understand the advanced techniques in intelligent condition monitoring.

There will also be a case study to illustrate the use of Hybrid Wavelet Neural Networks (HWNN) for tool condition monitoring and tool life prediction with a CNC high speed milling machine.
