An impulse takes raw data, uses signal processing to extract features, and then uses a learning block to classify new data.

Description	Recommended
Time series data Operates on time series sensor data like vibration or audio data. Lets you slice up data into windows.
Images Processes discrete images for object detection or classification.

Did you know? You can bring your own DSP code.
