Underfitting in classification - correct answer Increased number of neighbours means that more observations are influencing the classification. This smooths out the boundaries between each class, so the model isn't influenced enough by the training data. Underfitting in KNN regression - correct answer Increased K values means that more observations are influencing the regression line, which can cause the line to beco...
