感谢您的工作！想问一下LPS、SPC和SPA具体在代码中是如何实现的

[SUZILI7]

这几个分别对应的是TokenSparse类，TokenAggregation类和CrossSparseAggrNet_v2类吗

You're basically right.

LPS (patch selection) is for class TokenSparse
https://github.com/CrossmodalGroup/LAPS/blob/main/lib/cross_net.py#L14

SPC (patch calibration/aggregation) is for class TokenAggregation https://github.com/CrossmodalGroup/LAPS/blob/main/lib/cross_net.py#L61

SPA (patch-word alignment) is for def mask_xattn_one_text https://github.com/CrossmodalGroup/LAPS/blob/main/lib/cross_net.py#L203 https://github.com/CrossmodalGroup/LAPS/blob/main/lib/xttn.py#L225
