Require some Skill hints on training

[brianchen]

Hi, 

 Just train the BME688 kit to learn cafe and clean air. After training, I test the prediction capability and found U1 and U3 cannot distinguish cafe and air.

U2 and U4 can correctly identify cafe and air, but it slow response to environment change.

Is there some skill hints relative to training procedure, specimen collection, etc. so that I can make a high accuracy system?

Hi brianchen,

Where do you collect data, train, and test at the cafe?

Share my learning experience:

1. Read Datasheet and Application Note first

2. Use Kit and AI Studio, and practice to training AI to recognize differnt smells

3. port API to my board

4. port BSEC to my board

Not difficult. Good documents. Thanks!

I found there're data confusion when I switch from cafe to clean air.

When I try to collect data in pure cafe and clean air, and cut the data while transfering space, it got much better result.
