Fit a random forest model to all of the predictors, then estimate the variable importance scores:

Did the random forest model significantly use the uninformative predic- tors (V6 – V10)? No, while they were used, the overall impact of uninformative predictors was very (close to 0).

Now add an additional predictor that is highly correlated with one of the informative predictors. For example:

Fit another random forest model to these data. Did the importance score for V1 change? What happens when you add another predictor that is also highly correlated with V1?

The importance of V1 decreased; this happens because the importance is now being split to the duplicate1 variable since they were highly correlated.

simulated$duplicate1 <- simulated$V1 + rnorm(200) * .1 
cor(simulated$duplicate1, simulated$V1) #simulated now has duplicate1 included

Use the cforest function in the party package to fit a random forest model using conditional inference trees. The party package function varimp can calculate predictor importance. The conditional argument of that func- tion toggles between the traditional importance measure and the modified version described in Strobl et al. (2007). Do these importances show the same pattern as the traditional random forest model?

Traditionals cforest shows V1 and duplicate still of high importance. They also shows that V2 and V4 also have high importance. In the conditonal the importance of V1 and duplicate1 decreases since this model provides a more balance view. The traditional RF doesnt adjust for correlation so V1 and duplicate1’s importance is perhaps inflated. Where as cforest is less biased and takes into account importance of variables without the influence of multicollinearity.

Repeat this process with different tree models, such as boosted trees and Cubist. Does the same pattern occur?

XgBoost account for the bias of collinearity and indicates that V4 and V2 are the more important predictors. Cubist seems to produce results that are off a bit, seeming to overfit the model. GBM model, however, while it typically adjusts for importance across correlated features it seems to be overestimating V1.

Accuracy with Low and High Granularity Tree are similar (slightly higher accuracy in low). High Granularity Tree performes slightly worse and that useing more details might not be beneficial.

8.3. In stochastic gradient boosting the bagging fraction and learning rate will govern the construction of the trees as they are guided by the gradi- ent. Although the optimal values of these parameters should be obtained through the tuning process, it is helpful to understand how the magnitudes of these parameters affect magnitudes of variable importance. Figure 8.24 provides the variable importance plots for boosting using two extreme values for the bagging fraction (0.1 and 0.9) and the learning rate (0.1 and 0.9) for the solubility data. The left-hand plot has both parameters set to 0.1, and the right-hand plot has both set to 0.9:

Why does the model on the right focus its importance on just the first few of predictors, whereas the model on the left spreads importance across more predictors?

The number of predictors is indicative of the two extreme values for the bagging fraction. 0.9 means 90% sample size is being used and allows the model to identify on a few dominant predictors that show consistent importance. 0.1 means the tree is using a small portion of the data which add a lot of randomness and spreads the model’s focus across more predictors. A high learning rate makes the model change more quickly with each step resulting a focus on few precuitors (or lower means more slowlyand focuses on more predictor).

Which model do you think would be more predictive of other samples?

The left hand plot- by using a smaller learning rate and bagging fraction, it generalizes better, and would be more predictive of other samples.

How would increasing interaction depth affect the slope of predictor im- portance for either model in Fig. 8.24?

Increasing interaction depth would make the left model spread its focus, while it would make the right model focus even more on a few key predictors.

8.7. Refer to Exercises 6.3 and 7.5 which describe a chemical manufacturing process. Use the same data imputation, data splitting, and pre-processing steps as before and train several tree-based models:

Which predictors are most important in the optimal tree-based regression model? Do either the biological or process variables dominate the list? How do the top 10 important predictors compare to the top 10 predictors from the optimal linear and nonlinear models?

Top 3 predictors are ManufactoringProcess32, BiologicalMaterial06 and BiologicalMaterial03. ManufactoringProcess variables still dominate the list. For all models ManufactoringProcess dominates the lost acors tree bases, linear and non linear. The RF model (tree) and SVM model (nonlinear) both shows 4 biological variables on top 10 whereas Ridge (linear) has only 1 biological variable on top 10. These 5 variables are present for all three models as top 10: ManufactoringProcess 32, BiologicalMaterial 03, ManufactoringProcess 9, ManufactoringProcess 13, ManufactoringProcess 36, ManufactoringProcess 17.

#using RF
var_imp <- varImp(rf_model, scale = FALSE) 

plot(var_imp, top = 10, main = "Top 10 Important Predictors - Random Forest")

Plot the optimal single tree with the distribution of yield in the terminal nodes. Does this view of the data provide additional knowledge about the biological or process predictors and their relationship with yield?

This view demonstrates that root split is based on ManufacturingProcess32 abd if its less than 0.19 or not. The split on BiologicalMaterial03 near the right side of the tree suggests that this biological factor may impact yield under certain conditions such as in scenarios where ManufacturingProcess32 is higher. It also seems that certain thresholds in the manufacturing variables strongly influence yield outcomes.
