replace transformerencoder with mamba about motion-diffusion-model HOT 9 OPEN

Hi @sunxin010205 , what is Mamba?

from motion-diffusion-model.

嗨，曼巴是什么？

Mamba: Linear-Time Sequence Modeling with Selective State Spaces，Mamba is a new architecture proposed for the linear complexity of transformer。
When I use mamba instead of transformer encoder, other loss is normal, only loss_q3 cannot be reduced. Do you know what the situation is? Looking forward to your early reply!

I'm not familiar with this one.
What's loss_q3?

Hi！ After replacing an eight-layer Transformer encoder with Mamba, the training loss fails to decrease. Could it be that Mamba doesn't perform as effectively as the Transformer in the diffusion model? Looking forward to your response。 Here are my codes.

I tried to replace the transformer layer with other architectures and encountered the same situation as yours, where the loss is around 2.4 and cannot be reduced. May I ask if you have found a solution later on?

Sry, I have not continued this part of the work at present, but my overall loss after replacement is about 0.2. If you can find the problem, could you please tell me the solution? I have some ideas. Perhaps the original encoder layer is not suitable after replacing transformer. You can try other encoder methods.

Thank you for your reply. I am also trying to use Mamba or a combination of Mamba with the transformer to replace the transformer layer. May I ask if you have conducted any experiments combining Mamba with the transformer?   苏紫欣 @.*** 广西师范大学  
感谢您的回复。我还尝试使用Mamba或Mamba与Transformer的组合来替换Transformer层。我能问一下你有没有做过将曼巴和Transformer结合的实验吗？

我用过4层mamba＋4层transformer，loss也可以正常的降下去，而且效果还可以。我采用的一层mamba和一层transformer交替的结构，然后速度可能会比较快一点，参数量基本相同。

The logger output during training looks like this, I can't find the definition of loss_q3 in the code.

| grad_norm | 1.84 |
| loss | 1.37 |
| loss_q0 | 1.33 |
| loss_q1 | 1.21 |
| loss_q2 | 1.11 |
| loss_q3 | 1.82 |
| param_norm | 462 |
| rot_mse | 1.37 |
| rot_mse_q0 | 1.33 |
| rot_mse_q1 | 1.21 |
| rot_mse_q2 | 1.11 |
| rot_mse_q3 | 1.82 |
| samples | 64 |
| step | 0 |
