Implement an AdaBoost with boosting stumps (30 points) and apply the algorithm to the breast cancer data set [login to view URL], ID 322391. The data set contains 30 features and asks for a classification of breast tumors into benign and malignant. Plot the classification errors over the iterations and use 5-fold cross-validation to validate your results (70 points). Hint: you need to calculate the average cross-validation errors minus and plus one standard deviation. Decision stumps are often used as components (called ”weak learners” or ”base learners”) in machine learning ensemble techniques such as bagging and boosting. A boosting stump is a machine learning model consisting of a one-level decision tree. That is, it is a decision tree with one internal node (the root) which is immediately connected to the terminal nodes (its leaves). A decision stump makes a prediction based on the value of just a single input feature. Question 2. (100 points) Implement a Bagging with bagging stumps (30 points) and apply the algorithm to the breast cancer data set [login to view URL] Plot the average bootstrap errors plus or minus one standard deviation and compared with those in Adaboost procedure

Hi there, I have experience with using R and caret for machine learning in the context of genomics applications. I will provide R scripts for the analysis that you described. I will also provide RMarkdown documents with comments, plots, interactive tables, and the original code. These models can be accessed through the caret package and I will be able to complete this project within 72 hours. Best, Justin

Dear Madam or Sir, I have great experience in machine learning. As a mathematician, I am familiar with the theoretical background and as a software developer I know how to develop clear and documented code. I have implemented all the standard machine learning algorithms ((P)PCA, FA, LDA, QDA and other mixture models, simple NN) in Matlab, Python, R, or C++ from scratch. In particular, I have already implemented adaboost and bagging with decision tree stumps in Matlab and Python. Moreover, I have great experience in R, hence the success of this project is guaranteed. I am looking forward to discuss all these details in the chat. You might have a look at my reviews before making you decision. Best regards
