Hi @overshiki, you can specify that a RangeParameter
is an integer using ParameterType.INT
.. E.g. RangeParameter(name="x", parameter_type=ParameterType.INT, lower=1, upper=10)
. By default, Ax will apply an IntToFloat
transform on generated candidates that basically does (1). You can see all the default transforms here. If you are generating batches of new candidates and you are using sequentially (greedy) selecting each point in the batch (the default in Ax), where each candidate in the batch is sequentially selected and subsequent candidates are conditioned upon the already selected points, then each new candidate is rounded before the successive conditioning to improve the optimization performance. The docs mention that you can use integer RangeParameter
s here, but I will add a better description as to the behavior.
from ax.
Also, you can see how the transformation / untransformation happens before and after a point is generated here, similar to how you describe in (1):
