benwtrent opened a new issue, #13922:
URL: https://github.com/apache/lucene/issues/13922
### Description
It would take a bit of refactoring, but:
```
float dx = v - minQuantile;
float dxc = Math.max(minQuantile, Math.min(maxQuantile, v)) -
minQuantile;
float dxs = scale * dxc;
float dxq = Math.round(dxs) * alpha;
if (dest != null) {
dest[destIndex] = (byte) Math.round(dxs);
}
return minQuantile * (v - minQuantile / 2.0F) + (dx - dxq) * dxq;
```
All these actions seem like they could be done lane-wise. Though, I expect
the transformation from `FloatVector` to `byte[]` array to be the most
expensive part and consequently, might make vectorizing this effectively
impossible.
of course, much of the stuff here written for value reuse would have to be
adjusted
