Claim 8:
9. A system comprising:
a memory configured to store processor-executable instructions and a plurality of data sets, each data set of the plurality of data sets including multivariate time series data for a respective sample period of a plurality of sample periods; and
one or more processors configured to execute the processor-executable instructions to cause the one or more processors to:
for each data set of the plurality of data sets, determine recurrence data indicative of recurrent states in the data set;
for each data set of the plurality of data sets, determine, based on the recurrence data, determinism values of a determinism metric and laminarity values of a laminarity metric;
determine that a particular data set of the plurality of data sets includes data representing an anomalous state based on a determinism-laminarity curve representing the particular data set, wherein the determinism-laminarity curve is based on the determinism values of the particular data set and the laminarity values of the particular data set; and
generate output data indicating the anomalous state.
