        ### About 
        
        MHCLovac uses Bayesian linear regression for binding affinity prediction
        based on modeled physicochemical properties of peptides.
        MHCLovac uses pre-developed [**`proteinko`**](https://github.com/stefs304/proteinko) 
        package to obtain modeled distributions of physicochemical properties. 
        
        ![modeled_distributions](https://raw.githubusercontent.com/stefs304/proteinko/dev/resources/plot1.png)
        
        Physicochemical properties in question are:
        * Hydropathy
        * Number of donor hydrogen bonds
        * Number of acceptor hydrogen bonds
        * Isoelectric point
        * Van der Waals molecular volume
         
         Once the distributions are obtained, the area under the curve (AUC) is 
         calculated using a sliding frame technique. The AUC values for each of five
         physicochemical properties are concatenated into single feature vector. 
         
        Model training is performed on standardized AUC values. We tested number of 
        linear regression models and concluded that BayesianRidge algorithm from `sklearn`
        package produces most consistent predictions across various training set 
        configurations.

        MHCLovac makes modestly accurate predictions, which can be seen on plots below.
