1. A system comprising:
a formation tester tool to be positioned in a borehole, the borehole having a fluid, the formation tester tool comprising a sensor to detect time series measurements from a plurality of sensor channels, the time series measurements comprising measurements of at least one attribute of the fluid;
a processor; and
a machine-readable medium having program code executable by the processor to cause the processor to,
dimensionally reduce the time series measurements to generate a dimensionally reduced set of reduced measurement scores at least one point of the time series measurements in a multi-dimensional measurement space including performing at least one transformation of a first data set of the time series measurements into a second data set having a dimensionality that is less than a dimensionality of the first data set, and
determine one or more properties of the fluid at a time point based at least in part on the dimensionally reduced set of reduced measurement scores.
