Here i am going to explain how to calculate number of working dates between to given dates. In my approach i am taking a table called Holidays which contains holidays as shown below Once you have this table , we need to use this table in our Datetime table to calculate IsworkingDay column. Now give the relationship between Datetime and Holidays tables as shown below DAX :  IsWorkingDay = IF (NOT(DateTime[Day of Week]= "Saturday" || (DateTime[Day of Week]= "Sunday")) && COUNTX(RELATEDTABLE(Holidays),2)<1,1,0) Now you can create calculated column or measure  Total Working Days Column =  SUMX (     FILTER (         'Datetime',         'Datetime'[Date] >= Tasks[Input Start Date]             && 'Datetime'[Date] <= Tasks[Input End Date]     ),     'Datetime'[IsWorkingDay] ) Total Working Days Measure =  SUMX (     FILTER (         'Datetime',

I am planning to start my career in Datascience and want to learn what are  machine learning models and algorithms. I have googled Before starting to learn and collected some of the points and wanted to share with you what i understand , we should understand  following main steps in analysis using machine learning models: 1. Diagnosing the data – before defining the possible approaches to work with data, it is necessary to analyse the raw data itself first. What kind of measurements are included,  which kind of models it is possible to apply to the data and defining the initial goal of the research. Try and identify all the metrics that are important to the business. The metrics we are optimising for have a profound effect on the solution we choose, so it is important to identify these early on. It also affects what alternatives there are to machine learning. 2. Data Preparation – merging data, imputing missing values or excluding variables with too many missing values,
