<p>[QUOTE=&quot;GDJMSP, post: 2014422, member: 112&quot;]Yeah I understand now, but that only makes it worse. If you are not programming in grading criteria at all, then what exactly do you program in ? There has to be a program or the computer can&#039;t do anything. What you are assuming is that the computer will learn how to grade by merely &quot;looking&quot; at coins that are already graded. There&#039;s a couple problems with that idea.</p><p><br /></p><p>First of all, you can&#039;t even teach humans to grade with that method, and they can think. So how can you expect a machine to do it ? Secondly, the coins that are being used, somebody has to grade them. So do you use coins all graded by one person or by many different people ? </p><p><br /></p><p>Now the idea of the computer system you are proposing is to remove the subjectivity from the grading system, right ? So that would mean that you could only have 1 person do the grading on all coins. Otherwise this computer that can supposedly learn, would learn the very subjectivity that you are trying to get rid of. So let&#039;s say you do have 1 person do all the grading. The only thing the computer can &quot;learn&quot;, assuming it can learn at all, is to grade coins the same way that 1 person does. But even that 1 person&#039;s grade is still subjective. And then what happens when half or more than half of all the people in the market disagree with the grades assigned by the computer ?</p><p><br /></p><p>You&#039;d be right back to where we are now.[/QUOTE]</p><p><br /></p>
