Raw data
The Raw Data block generates windows from data samples without any specific signal processing. It is great for signals that have already been pre-processed and if you just need to feed your data into the Neural Network block.
GitHub repository containing all DSP block code: edgeimpulse/processing-blocks.

Raw data parameters

Scaling
  • Scale axes: Multiplies each axis by this number. This can be used to normalize your data between 0 and 1.

How does the raw data block work?

The Raw Data block retrieves raw samples and applies the Scaling parameter.
