How does Adaboost+decision Tree do prediction to my data test?
Hello, I use adaboost parameter with decision tree inside. i use split validation to know the performance. adaboost produce 5 trees. the problem is when i focus to adaboost prediction on record number 6. the prediction is NO (TIDAK) But all of tree that produce by adaboost predict YES (ya) how can i know the calculation of…

Potential Problem Detected (Learner ignore example weights)
Hi All, I want to try Adaboost with my dataset . RandomForest is available in Adaboost. But "Input example set has example weights,but the learner will ignore them" warning is displayed. I wonder that why does it occur ? Am I using Adaboost correctly ? In this case, Can I use result of algorithm ? Thanks. I attached my…

Adaboost Decision Stump
Hey all, I have a Question about Decision Stumps in the Adaboost Algorithm, because in Literature it is recommended to use a "Weak Learner". First I implemented an Decision Stump in the Adaboost Operator with 10 Iterations, but the Trees looked identical and my results weren't as expected. I saw that in the Tutorial…

adaboost individual model performance
Im using adaboost + KNN for my data, which gives performance accuracy of 77.24. & precision, recall. Adaboost is configured with 10 iterations. is there any way to view the performance of model in each iteration and weights assigned in successive iterations in rapidminer? pl let me know. thanks regds thiru

Automodel meanAbsolute rootMeanSquared error and other missing algorithms
Hi, 1) Im trying to find meanAbsolute rootMeanSquared error in Automodel results. But these values are not available in auto model results ? 2) Part, Bayesian Network Algorithm are available in rapidminer ? like weka. 3) Boosting, bagging, KNN Algorithm are available in auto model ? 4) What is deep learning below neural…

"Two questions from Adaboost"
Hi, I'm new in rapidminer. I want to use "adaboost" to make my dataset more efficient and then feed it to neural network for predicting the outliers. I have two questions: 1) (adaboost result contained 1 to 9 models with diffirent weights.) I need to know which of these models is more trusty and operative? 2) The output of…

"AdaBoost performance on new data (test dataset) MUCH worse than without AdaBoost"
Hello, I have the following problem: I am working on dataset of data suitable for modeling the classification problem of digits recognition. The database consists of 64 normal attributes + one for the class. It consists of nearly 5000 examples and is divided for training set (30 digit-writers) and test set (another, new 14…

"multiple learners in AdaBoost"
I have a question about the AdaBoost operator. As I understood AdaBoost in several literature, AdaBoost uses, for every iteration, another simple base classifier for classification. But in RapidMiner Studio, only one learner can be chosen for AdaBoost. Did I may understand AdaBoost wrong? Why can only one learner be…

"Learners in Adaboost"
Hi! I'm triying to classify some data using adaboost, but the only learner that this accept is Naive Bayes, i cant's use decision trees. How can i solve this or is this the only way i can use adaboost?

Help with adaBoost
Hi everyone, I've a confusion with adaboost, I thought that adaboost was a multi classifier, that uses different models and then it combines them to have a final answer, but I can't put more than one model in it( I was expecting something like the method Vote), so can anyone explain me how adaBoost really works? And I've…

AdaBoost vs. BayesianBoosting
Hi! I'm goint o try some boosting for my bachelor's thesis. I haven't yet decided whether using AdaBoost or BayesianBoosting. Actually I don't understand all the differences. What I do understand is that BayesianBoosing can use different fractions of the example set for model fitting and performance estimation. I…
