The numerous missing value computation approaches for yeast data have been suggested in the literature. Throughout the past few years, investigators are keen on driving a lot of research effort on giving methodical assessments of the dissimilar computation procedures. The problem of controlling the missing values are designed with samples of tough microorganisms, such as yeast. Expensive strategies are present which has targeted to develop a varied collection of samples. They are regularly in effect for concurrently disturbing various small samples, but are greatly lesser effective for larger samples. The manufactured devices highlight interference rates after these minor samples having 5% of cells interrupted in 2 to 38 seconds range, frequently ignoring to indicate the organism interrupted or the small sample size. At the outset, maximum procedures continued to be evaluated by means of highlighting on the accuracy of the computation, using metrics such as the Correlation (uncentered), Correlation (centered), Absolute correlation (uncentered), Absolute correlation (centered), Spearman Rank correlation, Kendall’s tau, Euclidean distance and City block distance. This proves the best clustering range. In the proposed approach running time is also computed for the various used methods using the same above mentioned metrics. On the other hand, it has turn out to be strong that the attainment of the accuracy and running time of the whole yeast gene data had a better assessment in further applied relations by way of hierarchical clustering approach. Accuracy and running time are sorted out for both large and small samples once after computing the missing values. Running times of the different clustering methods in a yeast dataset are existing in the work for the missing value rate of 4%. The hierarchical clustering was the fastest among the specified clustering methods (K-Means (gene) clustering technique, Self-Organized Mapping and Principle Component Analysis). However, the SOM was still about 10 times faster than k means. The running time of the original hierarchical method was about one third for that of its proposed version.
