Where the article explains it
where each is a model’s normalized score on component benchmark i and each is a weight chosen by whoever maintains the index.
The passage around this formula
where each is a model’s normalized score on component benchmark i and each is a weight chosen by whoever maintains the index. That weight vector is an editorial decision, not a discovered fact, and two indices built from different component sets or different weights are measuring different constructs even when both are called “intelligence.” This is why Artificial…
