title: Time Series Model - Device/Customer wise
body: <p>I wanted to build a time series model - ARIMA, LSTM for eg. where I am trying to forecast a single time series column. But I wanted to do it say each customer wise. For instance: customer_name, date, metric is my data. I wanted to forecast what will be the metric for customer1 tomorrow. </p>
  
  <p>The actual question now is: How to include the categorical column customer_name to the model.
  I am good building model only with metric column but what I need is the metric for a particular customer.</p>
