1. A method comprising:
- receiving network data at a processor of an analytics device, the network data collected from a plurality of sensors distributed throughout a network to monitor network flows within the network from multiple perspectives in the network;
processing the network data at the processor of the analytics device, wherein processing comprises;
identifying features for the network data;
determining transition points for each of said features in a histogram;
grouping each of said features into bins of varying width in the histogram, wherein said width defines a range of said features in each of said bins;
wherein said transition points define bin boundaries in the histogram, said transition points selected based on a probability that data within each of the bins follows a discrete uniform distribution; and
inputting said binned features into an algorithm for anomaly detection.

Abstract
In one embodiment, a method includes receiving network data at an analytics device, identifying features for the network data at the analytics device, grouping each of the features into bins of varying width at the analytics device, the bins comprising bin boundaries selected based on a probability that data within each of the bins follows a discrete uniform distribution, and utilizing the binned features for anomaly detection. An apparatus and logic are also disclosed herein.
