Query: A Review of Changepoint Detection Models   The objective of the change-point detection is to discover the abrupt
property changes lying behind the time-series data. In this paper, we firstly
summarize the definition and in-depth implication of the changepoint detection.
The next stage is to elaborate traditional and some alternative model-based
changepoint detection algorithms. Finally, we try to go a bit further in the
theory and look into future research directions.
