Implementation of Core Modules in FreePCA

[XiaokunFeng]

Thank you for your great work! After reading through your code, I have some questions I'd like to ask:

1. Regarding the Consistency Feature Decomposition and Progressive Fusion operations, I couldn't find the code that implements these operations. Could you please point them out?

2. As for the Reuse Mean Statistics, I noticed that in the execution process, the x_T obtained through this operation is not used, as shown in the image below. Could you explain the purpose of this operation?

Thanks for attention!

1. Please check the file FreePCA/lvdm/modules/attention.py, I have added some annotations for the convenience of reading.
2. Just cancel the comments. I forgot to change it back when I was doing the ablation experiment. Thank you for the reminder.
