There will be many ways to generate a brain clone, just as there are many ways to analyze training data sets now. In addition to training data, we will use test data to determine which of your brain clones is most like you.
Written Test
You will provide answers to a written test. The brain clones that score highest on the test will be judged to be most like you. Highest ranking clones can then undergo further training interations and can be tested again.
Video Responses
You will provide video responses to question. The brain clone will respond to the same questions, and be evaluated by another program or by people that know you.
Experts
There are people that know you well. They can evaluate your brain clones and determine which is most like you.
