An improved fuzzy set-based multifactor dimensionality reduction for detecting epistasis

作者:

Highlights:

• This study proposes an improved MDR using the fuzzy sigmoid method (FSMDR) to detect epistasis.

• The 46 epistatic models and a large real data set are used to compare FSMDR with other MDR-based methods.

• The results demonstrate that FSMDR achieves superior detection rates than other MDR-based methods on epistasis detection.

• The fuzzy sigmoid method effectively improves the discrimination of two multifactor genotypes in MDR operation.

• FSMDR does not need to select the optimal adjustment parameters of fuzzy sets in practical data applications.
