Predictor Importance for Bagged Trees in Classification Learner App??

 Hello,

 
I have sucessfully used BaggedTrees in the classificationLearner app to classify my data. I would now like to know (and show) which of my predictors are most useful in determining class. How can I do this?
 
The scatter plots generated in the app are helpful, but not what I am looking for. I want something like a bar graph that shows the most and least relevant predictors, or ideally a decision tree which shows which predictors give the greatest class separations.
 
I have found examples of this with different set ups, but I can't figure out how to make them work for me. The command I have seen to make decision trees is: view(trainedModel.ClassificationTree,'Mode','graph')
 
I have also seen the predictor importance found using: imp = predictorImportance(ens)
 
However, these methods have not worked for me. My code is simply a data importation and the command to call the classifier: fit = trainedModel2.predictFcn(Table);
 
Any help would be HUGELY appreciated.

Hi,

1. Make sure to have exported the model (not the compact model) from the classification learner app. Then you find something like this by double click on your trained model in workspace. Important is that you have a ClassificationBaggedEnsemble:

2. If you have this model as a ClassificationBaggedEnsemble in your workspace, you can use:

USING MACHINE LEARNING CLASSIFICATION ALGORITHMS FOR DETECTING SPAM AND NON-SPAM EMAILS

    ABSTRACT We know the increasing volume of unwanted volume of emails as spam. As per statistical analysis 40% of all messages are spam which about 15.4 billion email for every day and that cost web clients about $355 million every year. Spammers to use a few dubious techniques to defeat the filtering strategies like utilizing irregular sender addresses or potentially add irregular characters to the start or the finish of the message subject line. A particular calculation is at that point used to take in the order rules from these email messages. Machine learning has been contemplated and there are loads of calculations can be used in email filtering. To classify these mails as spam and non-spam mails implementation of machine learning algorithm  such as KNN, SVM, Bayesian classification  and ANN  to develop better filtering tool.   Contents ABSTRACT 2 1.

Why are Fourier series important? Are there any real life applications of Fourier series?

A  Fourier series  is a way of representing a periodic function as a (possibly infinite) sum of sine and cosine functions. It is analogous to a Taylor series, which represents functions as possibly infinite sums of monomial terms. A sawtooth wave represented by a successively larger sum of trigonometric terms. For functions that are not periodic, the Fourier series is replaced by the Fourier transform. For functions of two variables that are periodic in both variables, the trigonometric basis in the Fourier series is replaced by the spherical harmonics. The Fourier series, as well as its generalizations, are essential throughout the physical sciences since the trigonometric functions are eigenfunctions of the Laplacian, which appears in many physical equations. Real-life applications: Signal Processing . It may be the best application of Fourier analysis. Approximation Theory . We use Fourier series to write a function as a trigonometric polynomial. Control Theory . The F
