The stacking model
WebFeb 2, 2024 · The stacking technique is best when all the sub-models are skillfully combined together. This article uses the five-feature selection technique because it affects the overall performance of the model. Unrelated or moderately related features may adversely affect the behavior of the model. WebMar 12, 2024 · The stacking model, random forests, and decision trees agree on a similar trend with the stacking model providing better prediction followed by random forest and decision trees. Loyal customers (class 1) are more satisfied than disloyal customers (class 0). Logistic regression too agrees on the trend, but it is linearly increasing.
