In this case the predicted value is not a number, but a name of a group or category (“black T-shirt”). In this tutorial (part 1 of 4), I will be covering the first two phases of predictive modelling. Tutorial 4: Model, Assess and Implement. These all have a wide range of exploration, graphing and predictive modelling options. It has 0% error and 100% accuracy. What is Predictive Analytics? Predictive analytics is the use of advanced analytic techniques that leverage historical data to uncover real-time insights and to predict future events. Look at column names. Of course, this is too dramatic. Overfitting example (source: Wikipedia with modification). What data do we have - While Company ABC may not have been tracking employee hours this year, they do have a sample of previous employee data from an in depth employee quiz performed 2 years ago. That’s what a computer would say, but it works with a mathematical model, not with gut feelings. The Junior Data Scientist’s First Month video course. (dot A). Note: if you have trouble downloading the file from github, go to the main page and select "Clone or Download" and then "Download Zip" as per the picture below. Tutorial 1: Define the Problem and Set Up, Tutorial 2: Exploratory Data Analysis (EDA). Data analytics is used in the banking and e-commerce industries to detect fraudulent transactions. In this case the question was “how much (time)” and the answer was a numeric value (the fancy word for that: continuous target variable). Say you are going to the shop and you are able to choose between black, white, or red T-shirts.
