Question/Issue: I’m new to ML. Tried test put BLE 33 in 4 different position, 0, 45, 90, 180 degree to flat table surface. Each angle tried 20, so total 80 samples. Go through all the process to get a model. But the result is quite bad. From my side, it looks so obviously x,y,z value, but why the result is so bad? What I did wrong?
Thank you !
