The video tutorial discusses the limitations of using accuracy as a metric and introduces AUC as a better alternative. It highlights the problem of class imbalance affecting AUC and proposes a solution using weighted cross entropy. The tutorial explains how to implement this solution by penalizing misclassifications of low-prevalence classes more heavily, thereby improving model performance. The video concludes with a plan to test the new approach in a subsequent lecture.
