Show all blocks anyway
Learns patterns from data, and can apply these to new data. Great for categorizing movement or recognizing audio.
Edge Impulse
Regression
Learns patterns from data, and can apply these to new data. Great for predicting numeric continuous values.
Edge Impulse
Anomaly Detection (GMM)
Enterprise
Find outliers in new data. A Gaussian mixture model (GMM) models the shape of data using a probability distribution. New data that is unlikely according to this model can be considered anomalous.
Edge Impulse
Anomaly Detection (K-means)
Find outliers in new data. Good for recognizing unknown states, and to complement classifiers. Works best with low dimensionality features like the output of the spectral features block.
Edge Impulse
Classification - BrainChip Akida™
Learns patterns from data, and can apply these to new data. Great for categorizing movement or recognizing audio. Only works with BrainChip AKD1000 MINI PCIe board.
BrainChip
FOMO-AD (Images)
Enterprise
Visual anomaly detection. Find outliers in new data. Extracts visual features using a pre-trained model on your data, and a Gaussian mixture model (GMM) models the shape of the features using a probability distribution. New data that is unlikely according to this model can be considered anomalous.

The enterprise version of Edge Impulse hosts custom blocks for you and makes
them available for your whole organization.
Try Enterprise free.
To use an Input block version, connect it to a DSP block version using the
Manage versions dialog on a DSP block page. The starred Input
block version is the one connected to the Primary learn block, via a DSP block.
Note
To use a DSP block version, connect it to a Learn block version using the
Manage versions dialog on a Learn block page. The starred DSP
block version is the one connected to the Primary learn block.
Note
The Primary learn block version is the one that will be used when a project is
deployed. When you set a Learn block version to Primary, any DSP and Input block
versions it connects to will automatically be selected for deployment.
