From the project
The motivation for this project is to create an electronic nose system using a low cost device. Essentially this means using an MCU rather than a small board computer (SBC) like MyRio or Raspberry Pi.
The motivation for this project is to create an electronic nose system using a low cost device. Essentially this means using an MCU rather than a small board computer (SBC) like MyRio or Raspberry Pi.
The benefits of using an SBC are that inference (that is, running the model on a new input to classify it) can stay in the realm in which models are built and a single script or two can take care of the whole model for both training and inference, via tools such as Matlab, Octave, LabView, TensorFlow etc.
