# Dataset Description

<h2>File descriptions</h2>
<ul>
<li><strong>train</strong> - The training set (‘ctr_n.csv‘ files) consists of a portion of Jampp’s click-through data over a period of 7 days, not necessarily chronologically ordered (however a time column is provided).</li>
<li><strong>test</strong> - The test set (‘ctr_test.csv‘) consists of a sample of Jampp’s traffic on the week following the training period (computed in the same way as the training set). Note: it isn’t labeled (i.e no Label column) since it is your job to predict these outcomes. It
does include an id column to be used for results submission.</li>
