Brief: Holds the output of inference, anomaly results, and timing information.
Description: ei_impulse_result_t holds the output of run_classifier(). If object detection is enabled (e.g. EI_CLASSIFIER_OBJECT_DETECTION == 1), then the output results is a pointer to an array of bounding boxes of size bounding_boxes_count, as given by ei_impulse_result_bounding_box_t. Otherwise, results are stored as an array of classification scores, as given by ei_impulse_result_classification_t.
If anomaly detection is enabled (e.g. EI_CLASSIFIER_HAS_ANOMALY == 1), then the anomaly score will be stored as a floating point value in anomaly.
Timing information is stored in an ei_impulse_result_timing_t struct.
Members:
  • bounding_boxes[] - Array of bounding boxes, if object detection is enabled.
  • classification[] - Array of classification scores (if object detection is not enabled)
  • anomaly - A higher anomaly score indicates greater likelihood of an anomalous sample (e.g. it is farther away from its cluster).
  • timing - Information about the time it took to execute sampling, preprocessing (DSP), and inference.
