I have a metric that is defined as $1 - Accuracy$ and I need a name for it. Is there a scientific name for the inverse of accuracy?

Seems as if there may be more than one definition for accuracy in common usage. Which do you mean?

I mean specifically accuracy. I have a metric that is defined in academics as blah_blah_accuracy and I can only compute 1-X of that metric. So, I was curious for the definition of the inverse of accuracy to call my metric blah_blah_(inverse of accuracy)

I don't mean to be a stickler, but what you're describing here isn't an 'inverse', it's a 'complement' (or, a particular type of complement if you're going down proper fuzzy theory, albeit 1-a is the commonest version used and the one typically implied unless explicitly specified otherwise). In fact, 'the complement of the accuracy' is a perfectly valid description for it and could be notated as $A^c$ (if accuracy is notated as $A$).

@TasosPapastylianou is right. You are looking for the complement, so long as $A$, and thus $A^c$ or $bar{A}$ is restricted to $[0, 1]$.

I've seen people use $text{error rate} = 1 - text{accuracy}$, on the premise that accuracy is the proportion of samples classified correctly, so the error rate is the proportion of samples classified incorrectly.
