Dear authors, before the code was released, my team and I tried to reproduce the results by implementing the method ourselves, but we found it tricky to pick the correct the hyperparameters to ensure that the model had a decent validation score. In other words, it was very hyperparameter-dependent, reaching very low validation when selecting the wrong combination. Did you also happen to find this?

Hi, The hyperparameters that need to be set for SQD seem to be many. However, we have found through extensive experiments on different settings that tolerant_noise set to [0.05-0.2], noise_scale_box set to [0.4-0.6], num_dn_queries set to 60, and experiments within these value ranges always result in stable gains and similar experimental results, though optimal performance is not always obtained.
