Your help to enhance my RNN-LSTM solution
Hello everyone, In the first place, I would like to thank you for this helpful RapidMiner community platform that helped me a lot in solving many issues in developing this early prediction model. Thus, I am seeking the RapidMiner community's advice regarding my process. Actually, I am trying to develop an early prediction…

Can confidence value for prediction be interchangeably be used with the likelihood for an event?
For example: 0.978 confidence (yes) can be implied as the likelihood (chances) of this event being true is 97.8%.

DBSCAN performance evaluation
Hi! I'm facing the following problem. I have to compare the performance of K-Means and DBSCAN on a given dataset. I can easily do it with K-Means: But I can't fit the DBSCAN block in place of the K-Means block. The outputs are different and there is no "Cluster Model" to feed the Performance block. The old version of…

Why are DBI using Local Random Seed and Determined Good Start Value same in K-Means
Hi, i'm working on text clustering using K-Means and Singular Value Decomposition (SVD). And i'm using parameter Local Random Seed and Determined Good Start Value to show the different. But the DBI value generated using Local Random Seed is always the same as Determine Good Start Value even though I have tried to enter a…

Error in Binomial Performance Classification Operator
Dears I use deep learning for time series prediction in a binary classification problem. The result sometimes just contains a value for prediction (e.g., just "false"). The binominal classification performance operator has an error in this scenario with this message: "The attribute prediction has 1 different values, must…

High Accuracy, low recall and low precision - how to optimise this?
Hi experts, I have a dataset with about 40,000 data and would like to do a classification. I have a binominal label (yes/no). To create the model I take a decision tree. Then I want to apply the created model to a training data set (30,000 data) via the operator Apply model. Overall I have a very high accuracy, of almost…

Hi! Please how good is Decision Tree in Regression?
I have used the Decision Tree Regression and other regression models (SVR, LR, ANN, GBT, RFR etc.) on my data, and the former is performing better than all. I also took a new set of data for test, and the decision tree still performed better. But I have read about Decision Trees having overfitting problems, can I keep my…

Is standard deviation reported when the Loop Parameters operator is used?
Hi. I have a CV where, if run on it's own (outside of a Loop Parameters operator) I get average accuracy and the standard deviation. However, when I run my CV within the Loop Parameters operator, changing the Neural Net training cycles, I only get accuracy reported for each of my training cycle settings. Is it possible to…

In what order can i use replace missing value and normalization?
Hello! :) I'm trying to build a classification model with RF and I have a data set with many missing values. I tried to use RF without replacing missing values but the performance is not good. For this, I'd like to replace missing values with average. What is the better order to insert the operator? Before or after…

Can I optimize a custom performance metric?
Hi, I want to generate a F beta score and change beta according to the weight I want to put on precision or recall. And then I would like to add it to a performance vector so I can optimize it.
