You can try to set lower 'expire' value, but in this case it is hard to predict memory usage (that will constantly change depending on your learning intensity) and you have to wait a while to get the result.

As a permanent solution I would recommend a separate redis instance for bayes statistic and volatile-ttl memory policy.
