"Numerical issues" Warning building model, then very bad accuracy #1

Closed dbuezas closed 8 years ago

dbuezas commented 9 years ago

I added some new points to the face training images and configured the tool to take them into account. I get the following Wargning:

/Library/Python/2.7/site-packages/sklearn/preprocessing/data.py:153: UserWarning: Numerical issues were encountered when centering the data and might not be solved. Dataset may contain too large values. You may need to prescale your features.
  warnings.warn("Numerical issues were encountered "
/Library/Python/2.7/site-packages/sklearn/preprocessing/data.py:169: UserWarning: Numerical issues were encountered when scaling the data and might not be solved. The standard deviation of the data is probably very close to 0.

And the precision of the tracker is horrible now.

Any tips? I started with the provided anotations.csv and adapted the model_viewer and pdm_builder to account for the new points.

Update: I generated the model.js from the original images and annotations and the result is also bad. Is there any trick I could try?

Hi, sorry for not replying to this sooner. I'm very busy finishing my master thesis, and also looking after a newborn, so don't have much time to follow up issues. Did you figure this out? As I understand you're trying to add more points to the model than the default 71.

Hi Audun, thanks for your message and I wish you luck with your master thesis.

Yes that's right, that is what I was trying to do. I also tried just to generate the model with the provided training data and somehow the results were also bad.

I am not working in this company anymore but I think they still want to get it going, feel free to contact them, it might be a good freelancing opportunity, I added the contact person as cc.

Best regards, David
