Starch is used to store energy and cellulose is a structural polysaccharide. The key differences that explain these functions are cellulose with high branching aids strong structures, and starch with low branching makes for easy energy release. beta 1-4 and alpha 1-6 glycosidic linkage of starch can create branches, and alpha 1-4 linkages in cellulose creates strength. the unbranched structure of starch makes it easy to process for energy, and the branched structure in cellulose creates strong bonds. alpha 1-4 and alpha 1-6 glycosidic linkage in starch creates branching, and beta 1-4 linkages in cellulose creates unbranched structures.

Bоnus Questiоn (5 pоints) The аbove figure is for the grаdient boosting аlgorithm for regression. Step 1. A new decision tree (DT) is trained with feature X and label r (i.e., residual) to predict the residual. Step 2. The predicted residual in Step 1 is multiplied by the learning rate and is added to the prior predicted The learning rate is between 0 and 1 for slow learning to avoid overfitting. Step 3. The residual is updated by subtracting the new DT in Step 1 multiplied by the learning rate. Step 4. The final predicted Y in the gradient boosting is the additive function of DTs multiplied by the learning rate in each stage. Overall, gradient boosting is a (1) _____________ (a. parallel learning, b. sequential learning; 1 point). In addition, a new decision tree in each stage is created based on the information from the prior trees to improve performance. Based on the algorithm, which one is not a hyperparameter for gradient boosting? (2)_________ (2 points) the number of trees the maximum depth of each tree learning rate dropout rate the number of splits in each tree
