I am working an algorithm which I would like to test it on anomaly detection. But unfortunately, it is not yet proper for imbalance dataset, in which instances from one class is much less than the other one.
So the question is
Are there any anomaly dataset which is not imbalance? And how to download it?
Note that, here by anomaly I mean some unwanted item:activity/object,etc, which is , not obvious by looking into a single item. For example, it may be many attacks into a network, but they may not be obvious by looking into any transaction of attacker to the network, but in the overall activity of the attacker.
