title: What is the purpose of machine learning? Can we use something else to predict the future data instead of machine learning method?
body: <p>I started studying machine learning in R and I was just curious...</p>
  
  <p>We are trying to find the model with good accuracy by using train and test data for prediction... but instead of using machine learning process, can't we predict the future with Regression model?</p>
  
  <p>I just want to know how machine learning can change the results... will the plot of machine learning model be different with Regression model plot?</p>
  
  <p>I'm just curious... </p>
