    <dct:description>&lt;p&gt;Development of a method to estimate gene functions is&lt;br&gt; an important task in bioinformatics. One of the approaches for the&lt;br&gt; annotation is the identification of the metabolic pathway that genes are&lt;br&gt; involved in. Since gene expression data reflect various intracellular&lt;br&gt; phenomena, those data are considered to be related with genes&amp;rsquo;&lt;br&gt; functions. However, it has been difficult to estimate the gene function&lt;br&gt; with high accuracy. It is considered that the low accuracy of the&lt;br&gt; estimation is caused by the difficulty of accurately measuring a gene&lt;br&gt; expression. Even though they are measured under the same condition,&lt;br&gt; the gene expressions will vary usually. In this study, we proposed a&lt;br&gt; feature extraction method focusing on the variability of gene&lt;br&gt; expressions to estimate the genes&amp;#39; metabolic pathway accurately. First,&lt;br&gt; we estimated the distribution of each gene expression from replicate&lt;br&gt; data. Next, we calculated the similarity between all gene pairs by KL&lt;br&gt; divergence, which is a method for calculating the similarity between&lt;br&gt; distributions. Finally, we utilized the similarity vectors as feature&lt;br&gt; vectors and trained the multiclass SVM for identifying the genes&amp;#39;&lt;br&gt; metabolic pathway. To evaluate our developed method, we applied the&lt;br&gt; method to budding yeast and trained the multiclass SVM for&lt;br&gt; identifying the seven metabolic pathways. As a result, the accuracy&lt;br&gt; that calculated by our developed method was higher than the one that&lt;br&gt; calculated from the raw gene expression data. Thus, our developed&lt;br&gt; method combined with KL divergence is useful for identifying the&lt;br&gt; genes&amp;#39; metabolic pathway.&lt;/p&gt;</dct:description>
