Claim 13:
14. A system comprising:
data processing hardware; and
memory hardware in communication with the data processing hardware, the memory hardware storing instructions executed on the data processing hardware and causing the data processing hardware to perform operations comprising:
receiving a point data anomaly detection query from a user, the point data anomaly detection query requesting the data processing hardware to determine a quantity of anomalous point data values in a set of point data values; and
in response to receiving the point data anomaly detection query:
training, using unsupervised learning, a model using the set of point data values;
for at least one respective point data value in the set of point data values:
determining, using the trained model, a variance value for the at least one respective point data value;
determining that the variance value satisfies a threshold value; and
determining that the at least one respective point data value is an anomalous point data value based on the variance value satisfying the threshold value; and

reporting the determined anomalous point data value to the user.
