Fuzzy logic System for DNA Profile Matching with Embedded Ethnic Inference

This paper proposes a novel technique to do probabilistic inference by using simple Fuzzy logic System (FlS), especially ethnic information in DNA profile matching algorithm. By using the allele marker’s distribution probability density function as the membership function in the FlS, the new technique makes it possible to tell the ethnic similarity between two DNA profiles in a fast and simple way. A data acquired from ethnic groups of Indonesia is used to test the technique and produced promising result, being able to indicate higher ethnic similarity score within an ethnic group and lower similarity between ethnic groups. However, further research is needed to further improve the model and warrant the correctness and accuracy, especially because the data is not very discriminative.
