Another approach is based on identifying outliers in the set of code-phases.

The method may be used in particular for identifying anomalous (novelty or outlier) features within the scene.

The new events may be analyzed and reported to a web session operator based on their contribution to any identified outliers.

In some embodiments, statistics may be generating regarding an outlier in the data, a directional trend in the data, or variability of the data.

Even if no outliers are detected, the new events having a most significant impact on web session operating conditions may be identified and reported in real-time.
