K Nearest Neighbour (KNN ) is one of those algorithms that are very easy to understand and it has a good level of accuracy in practice. In Part One of this series, I have explained the KNN concepts. In Part 2 I have explained the R code for KNN, how to write R code and how Read more about Prediction via KNN (K Nearest Neighbours) KNN Power BI: Part 3[…]
In the previous post (Part 1), I have explained the concepts of KNN and how it works. In this post, I will explain how to use KNN for predict whether a patient with Cancer will be Benign or Malignant. This example is get from Brett book. Imagine that we have a dataset on laboratory results of some patients Read more about Prediction via KNN (K Nearest Neighbours) R codes: Part 2[…]
Data Scientist is a hot job nowadays in the market and there are lots of demand for it. Data Science origins from the BI field and sits under umbrella of Business Intelligence, because the data science and data mining helps decision makers in their decision making process. To have an idea about how data mining can solve real world issues, think about loyalty program of the super market that you usually use close to your home. Loyalty program simply analyze your purchase history and based on that it comes up with some suggestion and prediction about your next purchases and will promote that through your cell phone text messages or email or even flyers directly addressed to your home address.
