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[1]. 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[…]
K Nearest Neighbor (KNN ) is one of those algorithms that are very easy to understand and has a good accuracy in practice. KNN can be used in different fields from health, marketing, finance and so on [1]. KNN is easy to understand and also the code behind it in R also is too easy Read more about Prediction via KNN (K Nearest Neighbours) Concepts: Part 1[…]
In the Part one I have explained the main concepts of Market basket analysis (associative Rules) and how to write the code in R studio. In this post I will explained the process of doing market basket analysis in Power BI. for doing this post I have used the data set from [1]. Power BI Desktop, is Read more about Make Business Decisions: Market Basket Analysis Part 2[…]
DAX has many functions to write conditional expressions. For example you might want to calculate sum of sales amount for all “Red” products. you can achieve it by using SUMX or Calculate, and functions such as IF or Filter to write a conditional expression for product color to be equal to “Red”. At the first Read more about IF and Filter are Different! Be Careful (DAX)[…]
In previous posts, I have showed the process of creating a live weather data streaming with Cortana. In Part 1 the process of setting up Raspberry PI3 and weather station sensor has been explained. Following, in Part 2, the process of setting up the Event Hub as a median to digest the data from Raspberry PI Read more about Part 4 – Live Streaming Weather Station with Cortana Analytics (Online Data Analytics with Azure ML)[…]

I have previously written some blog posts about Map visuals in Power BI. One of them was specifically about Filled Map, titled as Filled Map; the Good, the Bad, the Ugly! Why? you need to read that post to find the reason. In this post I want to explain the power of Shape Map which Read more about Shape Map Better than the Filled Map[…]
There are many ways to share Power BI content with others. I have previously written about some of these methods, including Workspaces (or groups) in Power BI, Publish to Web, and Power BI Embedded. In this post, you will learn about organizational content pack which is another method of sharing. This method is a recommended Read more about Content Pack; Sharing, Self-Service and Governance Together[…]
What is the main difference between M and DAX? Why we can do a calculated column in two different places? What are pros and cons of each? Which one should I use for creating a profit column? Why I cannot do all of it in only one; DAX or M! Why two different languages?! Why Read more about M or DAX? That is the Question![…]
