title: Determining the movie popularity for upcoming movies with neural network
body: <p>I have a CSV data set consisting of a movie details per line.
  These are: name, budget, revenue, popularity, runtime, rating, votes, date released.</p>
  
  <p>I'm wondering how to split the data set into training, validation and testing sets?</p>
  
  <p>Then of course, how to get some results?</p>
  
  <p>It would be nice to get a brief step-by-step intro on where/how I should begin.</p>
