Convert categorical variables into dummy variables
Hi, I want to perform a regression task to predict continuous response. I have 4 categorical variables, others are numerical. Categorical variables are:age=(≤20, 21-35, 36-50, ≥51)gender=(Female, Male)income level=(1=insufficient, 2=sufficient)BMI range=(1=<25, 2=>25)*Income level & BMI are keyed in as numerical code in my…

Explain me about this Support Vector Machine training set graph?
I made a support vector machine classification with supplied training set of VADER labelling for positive and negative sentiment (1000 positive sentiment and 400 negative sentiment). I don't understand why the graph for positive sentiment is negative on the function value? and why my negative sentiment is having a negative…

Applying Word2vec on a dataset of texts
Hi, I created ad SVM model for text classification and I want to share the process with you to have any advise to improve it. The purpose of this classificator is to classify a dataset of comments, reviews, or sentences in general, into positive and negative and the dataset I used for its training was made of 2400 tweets…

SVR, kernel gamma, c, bias
Hi Community, I am running a support vector machine regression and the model is giving the bias as my predicted values for all my data points even though they are different values. I have used different kernel gamma values, different C values, yet I face the same effects. My model is based on the RBF, can I get a…

Attribute do not match - Text mining 、Sentiment analysis
I import the training set and want to predict the test set through the model. The training set is the Amazon website reviews and user ratings, the test set is also the user reviews, but because the training set and test set reviews are different, different words will be separated using the word segmentation operator, how…

good multinomial Naive Bayes or libSVM Text Classification
Hi everyone, I am relatively new to RapidMiner and machine learning in general. In the
forum I couldn't find anything that would solve my problem, sorry if I
missed something there. I want to build a model which classifies the correct party from a given speech. I have a large corpus with
around 20 000 speeches, which are…

How are the anomaly scores computed for pca, knn, svm,
Hi Anomaly Detection Experts, I have carefully read the papers underlying these anomaly detection algorithms, but getting surprising results. I am puzzled how is temporal aspects captured in these spatial algorithms. What have you done ? It is not stated anywhere that I can find. I am pulling my hair out, trying to figure…

GO won't work at all
I just recently got the monthly subscription for GO but it gets "hung up" (at times all night even on something with 80 rows and 3 columns!)!) and won't deliver any conclusions even on older files for which it was successfully predicting. So, I suspect it has nothing to do with the process or the particular files. Any…

Some Questions Regarding Clustering
HI Everyone! - Hope all are safe, healthy and happy this evening. I have several and "apparently" atypical questions regarding 3 "newer" clustering methods. I wish to use them on polynomial data imported from an Excel spreadsheet with approximately 300 rows, 45 columns and lots and lots of missing values. 1. The Confusion…

Need Hand Holding!! HELP!!!
Hi folks - I was drawn to RapidMiner Studio because of its "no-code" environment from an industry outside of computer science, and hence have no programming chops whatsoever. I'm trying to set up a simple time series prediction model with 20 attributes and 1 label upon which to predict. There are approximately 75 rows in…

Processing input and output for Test Data - SVM
Dear all, I am noticed that when I perform the same data processing steps for testing(unseen/unlabel dataset), the output of processing eliminates the column (it eliminates the regular attributes and only return the label) i.e. different from the output of processing for training dataset where the output of training…

Number of Clusters for Support Vector Clustering (SVC)
Dear community, I applied the SVC approach based on high dimensional data with the default setting (kernel type: radial) and got only one sole cluster as result. This suprised me a lot. How to set the number of clusters for SVC? In this connection, is there a possibility to evaluate and validate the number of clusters of…

support vector machine cannot handle polynominal attributes
At first i had an error in the nominal to numerical whenever i choose to transform the attribute prediction label it gave me an error and it doesn't include it in the output set then i checked the special attribute box it doesn't produce an error but it also doesn't include it on the output set and now i'm having the error…

How to compare the SVM and random forest results?
Hi, I am trying to use the prediction in Auto Model but encountered several questions on the results of SVM and random forest. * I wonder why the results of SVM and RF barely match? For example, attribute 1 has the highest weight based on SVM result, but it became one of the attributes having the lowest weight in the RF…
