Processing of Shapley Module

[Kaihui-Cheng]

It is a good idea to incorporate the Shapley value into balanced multi-modality learning. However, I couldn't locate the Shapley module in this project. Could you please help me find its location? Thank you.

You can find it under the model initialization.

Okey, I find it. Another question: in AGM Equation (1) shows $S\neq \varnothing$. But if so, in Equation (3), why there is $\phi(m_1,0^{m_2})$.

$\phi(m_{1}, 0^{m^{2}})$ is used to mute the input of modality $m_{2}$. The details of the Shaply theorem can be found in "SHAPE: An Unified Approach to Evaluate the Contribution and Cooperation of Individual Modalities".
