LSTM Replaces MIMO MPC

Thank you for the great content!

Hi! Really thanks for the video, I've only one curiosity if someone can answer! How do we select the hyperparameter in this case? Are there techniques as K-fold-cross-validation that can be used?

[@apm]

There are packages that test hyper parameters in an intelligent search method. One that I recommend is Hyperopt. K-fold cross validation is typically used to remove the effect of choosing a particular validation set.

@@apm thanks for the answer! Maybe I'm misunderstanding, is not the K-fold cross validation used to validate a model basing on its accuracy?

[@apm]

@@eliaburattin7907 yes, that is correct. It could be used as a metric when selecting hyper-parameters. Here is more information on K-fold cross validation with example code in Python: apmonitor.com/pds/index.php/Main/SplitData

​@@apm thanks again for your answer! Only one doubt remains, assuming that we are using the K-fold cross validation as a metric for hyper-parameters selection, there shouldn't be problems related to the independency of the samples? I know that one of the assumptions of that kind of method coincides with the fact that them are iid but in the time-series case this doesn't hold anymore. So can I use it in the classical way or some adjustments are required?

@@eliaburattin7907 Good observation. I would recommend a completely separate set of data for validation to optimize the hyper-parameters.

Hi, can you help me with masters subject? I need to program MATLAB of (flashing fluid critical flow calculation) It's a scientific paper endtitled ( solve flashing - fluid critical - flow problems ) The results are shown in a table. I want to make the results, on the MATLAB program and show at what pressure the flashing occurs in figure

Unfortunately, I can't help with the specifics of the many requests I receive each week. Good luck with your application.

Hi guys! Im in a group thats currently writting our thesis on energy effectivizing pumps (by PID controlling the pumps) but we're having a Haaaaaard as time modelling the system on Matlab. This might be a shot in the dark, but if theres anyone thats had to write about the same thing/knows about literature on the topic or knows of other resources on how to model the system on Matlab that would be greatly appreciated!
