Title
Data-Driven Machine Learning and Optimization for Industry
Abstract
Today, industrial processes (e.g., in production) generate a significant amount of process data through sensor measurements. In this talk, we will show how data-driven machine learning and optimization algorithms can be enhanced and applied to such processes for optimizing one or multiple objectives, such as product quality criteria and robustness.
To achieve this, a range of methods including supervised learning (regression and/or classification), hyperparameter optimization, and multiple criteria optimization need to be combined and applied, often in an automatic way. Moreover, enhancements of such algorithms need to be developed to fit the requirements of such industrial processes, including the on-line application of predictive models.
In this presentation, we illustrate this approach towards data-driven machine learning in industrial processes by means of some practical examples from the automotive industry. In addition to the supervised learning approach for product quality optimization, we will also show an example of unsupervised learning for anomaly detection in high-dimensional feature spaces.
To make such techniques applicable in industry, algorithmic developments such as a new algorithm (global-local outlier detection in subspaces; GLOSS) for anomaly detection, a new cluster-Kriging approach for Gaussian process modelling, and enhanced imputation algorithms for missing value handling are required. In the talk we will briefly describe some of those new methods.
Combining the machine learning and optimization algorithms, an integrated approach for automatic modeling, prediction, and optimization for industrial production processes (and other machine learning tasks) is defined, which is applicable in a wide range of industries. A sample application in the automotive industry is used to illustrate the general approach.

Data Analytics Using Intelligent Techniques Inspired from Nature
Abstract
This talk highlights some of our recent research results in data analytics using intelligent techniques inspired from nature. Our algorithms include compact radial-basis-function (RBF) neural networks, incrementally-generated fuzzy neural network, granular support vector machines, semi-exhaustive search and class-dependent feature selection algorithms. We demonstrate our algorithms in various challenging data analytics problems, such as chip fault detection, glaucoma diagnosis, EEG signal classification, stock trading and time series prediction, fighter jet response tactics, scanning acoustic microscope image analysis, action recognition in videos, content-based image retrieval, gene selection in microarray data, and face recognition.
