Using Radiated Sound (RADSND) in Optimizations
Hello, I am working on utilizing the radiated sound method of external acoustic sound pressure measurements in hypermesh, and want to use this response output in optimizations. The standard outputs for responses in optimization do not directly point to acoustic pressure, but since this is a frf response technically, would…

DOBJREF definition
Hello, I'm trying to set up a MAXMIN optimisation and I want to use DOBJREF. I tried to define two references in HM2023 to point to 2 different responses with the same DOBJREF and HM doesn't agree with me - it says New entity id conflicts with existing id. I found this in the help file for DOBJREF: " The same DOID can be…

HyperStudy Tips and Tricks: #33 - HyperView Model Connection in HyperStudy
Hello HyperStudy users, HyperStudy reads results of a complete CAE model & defining output responses on specific components & sets (nodes/elements) is not available by default. Also, HyperStudy cannot add output responses for specific HyperView post-processing settings such as Corner Data, Averaging etc. by default. Hence,…

How can I optimize my credit card fraud outlier detection process?
Hello everyone, I am very new to rapidminer. Im currently working on a process in which I wish to detect credit card fraud with one of the detect outlier operators. I have found the best success with the Densities operator. I have taken a sample of 1000. The denseties operator finds there to be 381 outliers and 619 not…

Optimize Parameters (Grid) fails when applied to a larger set of data
Greetings community, Applying to the collective wisdom to find if anything could be done to help with Optimize Parameters (Grid) applied to a larger set of data/files. I am using this operator to find an optimal number of topics for LDA and re-run it separately to find optimal number of topic-words, as well. For finding…

Optimizer Parameter Grid (No result from optimizer)
Some time ago I had used with a similar dataset as today the optimize parameter grid and the results had the effect of improving the performance of the model. The data is reported on patient records. Due to the nature of the data a lot of it is missing, but the optimizer worked. Now that I have modified the dataset I get…

Is optimization possible in a multi-label problem?
For example, there is data with 7 variables, 2 of which are designated as prediction targets (labels), and for convenience, we will call them A and B (real type labels). A and B predictions could be performed without problems using multi-label modeling operators. In addition to this, what I want to do is a multi-label…

Ignore Deep Learning Errors!
Unfortunately, the Deep Learning module can not send its exception gentle and it fails the entire process, so, I can not use it in Optimize operators like Gird Search, because the entire process will fail by a configuration error! Besides, its errors are not clear and I can't understand how should I solve the problem…
