Question about 'forgetting'

[lif314]

I noticed that during the training process, some frames are initially optimized very well, with PSNR values exceeding 30. However, when I perform evaluation after the entire map optimization process, the rendering results for the initial frames are not satisfactory. Is there any good way to alleviate this issue?

I think it is a trade-off between the efficiency and the accuray.
One option might be enlarging the reply buffer;
The other option would be adding some regularization terms to regularize the optimization of Gaussian parameters.

I believe that enlarging the mapping window and some updates to our keyframing similar to this paper (https://arxiv.org/abs/2402.03246) should help.

What do you mean by "enlarging the mapping window"? Do you mean changing the parameter mapping_window_size in configs/splatam.py?
