=================================================== Get the code from here: https://gum.co/GViK =================================================== In this code I implement imputation algorithm to different datasets which is used in the case that the dataset has some missing data, this algorithm can very accurately estimates these missing data. This step is usually prior to any machine learning algorithm using this dataset like classification or model training which can't be done if the dataset has missing data. The algorithm combine both Gaussian mixture model (GMM) and K nearest neighbor (KNN) methods to get the best estimation to missing data as explained in the video. At the end the imputed dataset is compared to the complete and original dataset to measure how good is the estimation algorithm using normalized root mean square error (NRMS).
