Classwise accuracy calculation

[AnilRahate]

@yaohungt , I am beginner, hence these questions. I am trying to understand how accuracies are calculated for IEMOCAP as it is multi class and multi label emotions. Do we need to use Sigmoid at the output layer with 4 output units so that it can provide predictions for class/multi label? Another question - How to use weighted accuracy function defined at below link for class wise accuracy?. Do we need to pass on class specific predictions and ground truths to this classification function and weighted accuracy function. https://github.com/yaohungt/Multimodal-Transformer/blob/master/src/eval_metrics.py

Thanks in advance.
