Evolutions in chemometrics. Plenary lecture

Abstract

Chemometrics started as part of analytical chemistry with the emphasis on statistics and pattern recognition. Although data processing still occupies a large part of chemometrics, new trends are emerging. The desire to lay a firm scientific base in analytical chemistry was a challenge to chemometrics. Information theory, state estimation and new ways of calibration are some examples of techniques that have emerged in the last 10 years. The desire to formalise and record analytical knowledge spurred the development of expert systems. Although these systems are available commercially many problems arise, for example, how to represent and introduce the vast amount of analytical knowledge. Development of learning systems will be required.
