Predicting the Types of Ion Channel-Targeted Conotoxins Based on AVC-SVM Model

الملخص EN

The conotoxin proteins are disulfide-rich small peptides.

Predicting the types of ion channel-targeted conotoxins has great value in the treatment of chronic diseases, epilepsy, and cardiovascular diseases.

To solve the problem of information redundancy existing when using current methods, a new model is presented to predict the types of ion channel-targeted conotoxins based on AVC (Analysis of Variance and Correlation) and SVM (Support Vector Machine).

First, the F value is used to measure the significance level of the feature for the result, and the attribute with smaller F value is filtered by rough selection.

Secondly, redundancy degree is calculated by Pearson Correlation Coefficient.

And the threshold is set to filter attributes with weak independence to get the result of the refinement.

Finally, SVM is used to predict the types of ion channel-targeted conotoxins.

The experimental results show the proposed AVC-SVM model reaches an overall accuracy of 91.98%, an average accuracy of 92.17%, and the total number of parameters of 68.

The proposed model provides highly useful information for further experimental research.
