Course Launch – Intro to Azure ML Studio with Regression

Online courses are a great way to share knowledge with others; that is why I have decided to launch a few courses. The first course is Intro to Azure ML Studio – Regression. This is a smaller course and should take about 2 hours to complete.

Azure ML Studio is a drag-and-drop interface for doing machine learning.

Topics are all based upon Azure ML Studio, and they include:

  • Linear Regression
  • Linear Correlation
  • Feature Selection
  • Splitting Data
  • Evaluating a model

9 problems with Real World Regression

This list comes from the Coursera Data Analysis Course.

Linear and Logistic Regression are some of the most common techniques applied in data analysis. Here is a list of possible problems with regression in the real world.

  1. Confounders – variable that is correlated with both the outcome and other variables in the model
  2. Complicated Interactions – how do the covariates interact
  3. Skewness – is the data not evenly distributed, heavy to one side or the other
  4. Outliers – data points that don’t fit the pattern
  5. Non-linear Patterns – not all datasets can be fit with a straight line
  6. Variance Changes
  7. Units/Scale issues – make sure the units are standard across the model
  8. Overloading Regression – too much complexity
  9. Correlation does not imply Causation
