What does the Average Label Performance Factor measure?

The Average Label Performance Factor is a metric that specifically assesses the predictive capability of a machine learning model with respect to each label present in the dataset. It analyzes how well the model can predict outcomes for individual labels based on a subset of training data. This is particularly important in scenarios involving multi-label classification, where the model needs to understand the unique characteristics of each label separately rather than just focusing on overall accuracy.

By evaluating prediction accuracy per label, this factor provides insights into which labels the model performs well on and which ones it may struggle with. Thus, having this understanding can guide further training or adjustments to improve model performance in multi-label contexts.
