3. Conclusion

In this paper we have presented a surveyof novelty detection using statistical approaches. Most of such research is driven bymodelling data distributions and then estimating the probabilityof test data to belong to such distributions. In such model-based approaches, one does need to specifyor make assumptions on the nature of training data. In addition, the amount and qualityof training data becomes veryimportant in the robust determination of training data distribution parameters. Statistical approaches however are cheap to compute and straightforward in their explanation of the techniques used. Their main competition for the noveltydetection task comes from a varietyof neural networks, something we discuss in our successive paper.
