Identifying gene function has many useful applications such as plant breeding, reproductive biotechnology in animals and drug discovery. The goal of this project is to identify Atlantic Cod gene function based on gene expression data and gene co-expression module membership. First, I will discuss the application of Support Vector Machines (SVMs) and Neural Networks (NNs) in predicting gene functions. In this project, I used AZURE Machine Learning Studio to apply SMOTE method, to build SVM models and NN models, and to use an Ensemble method to predict gene functions in Atlantic cod. To evaluate the performance of the different models, I used accuracy score, F1-score and recall score to get the best model to infer ten gene functions. Experimental results indicate that ensemble classification methods for gene function prediction in Atlantic cod outperform the second best model by 7.8% in average accuracy.
