About the Experimental Setup

[haohaodw]

I am very interested in your excellent work. I have some questions about the experiments. What temperature were the Regular and VCD in Table 1 and Table 2 tested? Looking forward to your reply !

We apply direct sampling without any temp normalization in our main experiments. For more ablations on decoding strategies, please refer to B.4. Effect of Different Sampling Strategies in the Appendix.

Thanks for your reply. When we use the default parameter settings in the code experiments/eval/object_hallucination_vqa_llava.py, does this mean that vcd is performing direct decoding? Is this default parameter setting consistent with the settings of the main experiment in the paper?

[LengSicong]

yes, it is doing direct sampling.

Thanks for your reply. How to use VCD in greedy search? What code do I need to modify?
