I have a question about model-based predictions when data is only available after the fact.&nbsp;Let me give you an example. I try to predict the result (HOME,&nbsp;AWAY or a DRAW) of the match based on data like number of shots, ball possession, number of fouls, etc.</p> <table border="1" cellpadding="1" style="width:500px"> <thead> <tr> <th scope="col">TARGET</th> <th scope="col">TEAM 1</th> <th scope="col">TEAM 2</th> <th scope="col"> <p>possesion</p> <p>team 1</p> </th> <th scope="col"> <p>possesion</p> <p>team 2</p> </th> <th scope="col"> <p>shots</p> <p>team 1</p> </th> <th scope="col"> <p>shots</p> <p>team 2</p> </th> <th scope="col"> <p>fouls</p> <p>team 1</p> </th> <th scope="col"> <p>fouls</p> <p>team 2</p> </th> </tr> </thead> <tbody> <tr> <td>HOME</td> <td>Arsenal</td> <td>Chelsea</td> <td>60</td> <td>40</td> <td>12</td> <td>8</td> <td>5</td> <td>7</td> </tr> </tbody> </table> <p>Let's say I'm already after training the model and I want to see if I can predict the upcoming match. However, this match is only a few days away and I want to know the result of the model today.&nbsp;I understand that if the match had already taken place and I had the data, I could test it on the model and get the result. The goal is for the model to predict what will happen before the match.</p> <p>Is it possible at all? What are my options? Should I only select pre-match variables? For example, last game form, match referee etc or should I aggregate the variables and include average possession, average shots and average number of fouls from recent matches?</p> Machine Learning https://ask.ghassem.com/954/how-to-predict-from-unseen-data Tue, 17 Nov 2020 16:18:28 +0000
