Re: Measure Weight Optimization

Hi Dr. Geijtenbeek, I guess on this topic, is there any way to grab the individual fitness values of each cost function term? I understand that the total fitness is given to us in the result file and the breakdown of all the cost function terms are in the GUI, but I wasn't able to find that breakdow...

Re: Measure Weight Optimization

Hi Dr. Geijtenbeek, I suppose that it would be a meta optimization, where I would have an optimization of the simulation trying to track the experimental data and another optimizer to optimize the weights in the fashion that you have proposed. Is there a way to perform that within SCONE? What would ...

Measure Weight Optimization

Hi Dr. Geijtenbeek, I was wondering if there is a way to optimize the weights of the cost function terms to produce the best possible output with the lowest fitness? I tried making the weights an optimizable parameter but the parameters did not appear within the parameters window. I found that there...

Abstract Integrator Error

Hi Dr. Geijtenbeek, Thank you so much for helping me understand SCONE and for your patience with me as I ask you these questions. I was wondering if you could explain this error that I ran into for me: Screenshot 2024-10-29 111918.png I plan to model a passive prosthetic by inputting an estimated pa...

Re: Evaluation Fitness vs. First Generation Fitness

Dr. Geijtenbeek, Sounds good. I will definitely try this method. Could you explain the difference of initializing the parameters with the controller and the .par file? To my current understanding, the optimization would start with the parameters set in the par file, but then use the optimizable para...

Re: Evaluation Fitness vs. First Generation Fitness

Dr. Geijtenbeek, I am not using a .par file to initialize my parameters. Though, now knowing this, I will start doing this from now on. In order to begin doing this, would I have to change my controller at all or would the .par file be replacing my controller? Do I add this par file in the main SCON...

Re: Evaluation Fitness vs. First Generation Fitness

Dr. Geijtenbeek, Thank you for your response. I am now wondering if it would be best to also update the standard deviations as well as the means after every optimization for my purpose. Ultimately, I would like to let my simulations search for more possible solutions after it begins with it's initia...

Evaluation Fitness vs. First Generation Fitness

Hi Dr. Geijtenbeek, I hope you are doing well and thank you for answering my previous inquiries. I was wondering if you would have any advice to begin the optimizations with the fitness that appears in the evaluation results. The first few generations of my optimization are usually a huge factor lar...

Re: Error Running Simulations Even Though Evaluation Completes

Yes! That post helped me out with running simulations with that error.

Thank you,

Re: Error Running Simulations Even Though Evaluation Completes

Dr. Geijtenbeek,

Nevermind! I found the answer in a previous entry.

Thank you!
