title: Use LightGBM to predict person who owns a row in CSV file
body: <p>I would like to use LightGBM to predict and classify various things about invoices in a CSV file.</p>
  <p>So I have a CSV file with training invoices. I would like to use LightGBM to determine which person &quot;owns&quot; each row in the CSV file, so to use LightGBM to predict and classify the person for each row in the CSV file. How can I do this? Are there any LightGBM example of this kind of classification?</p>
