In particular, we recommend a secure k-NN classifier in encrypted data over the cloud. The recommended protocol preserve data confidentiality.It also preserve privacy in case of input query of user.It also shield the patterns of data access. We use secure k-NN classifierin case of encrypted ...

While trying to predict changes in the price of Bitcoin, I found that the KNN classifier gave the best results. Wanting to further improve the results led me to learning about ensemble techniques, especially the unique formulations that have been developed to improve KNN. ...
