Figure 1. Overview of median-supplement methods
Figure 1. Overview of median-supplement methods. The scalar multiplication of the median expression of each gene and a corresponding column vector of a random matrix are aggregated to the gene expressions to form a median-supplement data. The random matrix is generated using a Latin Hypercube. A model for inferring receptor status of a new patient is constructed from the median-supplement data.

Figure 2. Accuracy of machine learning methods to identify HER2 status of breast cancer patients. (A) Performance on HER2 receptor data from a group of 162 instances of breast cancer patients. (B) Performance on HER2 receptor data from a group of 806 instances of breast cancer patients. Bars represent the rate of correctly identifying HER2 status of breast cancer patient. SVM is support vector machine, logistic is logistic regression, BN(RHC) is Bayesian network with repeated hill climbing search, BN(SA) is Bayesian network with simulated annealing, NB is Naive Bayes, RT is Random Trees, RF is Random Forest, MNB is median-supplement Naive Bayes and MRF is median-supplement Random Forest.

Figure 3. Accuracy of machine learning methods to identify PR status phenotype of breast cancer patients. (A) Performance on PR data from a group of 162 instances of breast cancer patients. (B) Performance on PR data from a group of 1146 instances of breast cancer patients. Bars represent the rate of correctly identifying PR status phenotype of breast cancer patient. SVM is support vector machine, logistic is logistic regression, BN(RHC) is Bayesian network with repeated hill climbing search, BN(SA) is Bayesian network with simulated annealing (excluded in (B) because of the size of data), NB is Naive Bayes, RT is Random Trees, RF is Random Forest, MNB is median-supplement Naive Bayes and MRF is median-supplement Random Forest.
