(Video) Sequence prediction with the CPT and CPT+ Models

Today, I presents the CPT and CPT+ sequence prediction models in a video. Sequence prediction is an important task in data mining which consists of predicting the next symbols of a sequence. It can be used for example to predict the next word that someone will type on a keyboard, or the next location where someone will go.

The official implementations of  CPT and CPT+ models and datasets for evaluating their performance are available in the SPMF software, which is implemented in Java and open-source. There is also an unofficial implementation of CPT in Cython.

The CPT+ (Compact Prediction Tree+) model is described in this article:

Gueniche, T., Fournier-Viger, P., Raman, R., Tseng, V. S. (2015). CPT+: Decreasing the time/space complexity of the Compact Prediction Tree. Proc. 19th Pacific-Asia Conf. Knowledge Discovery and Data Mining (PAKDD 2015), Springer, LNAI9078, pp. 625-636.

The original CPT algorithm was described in this paper:

Gueniche, T., Fournier-Viger, P., Tseng, V. S. (2013). Compact Prediction Tree: A Lossless Model for Accurate Sequence Prediction. Proc. 9th Intern. Conference on Advanced Data Mining and Applications (ADMA 2013) Part II, Springer LNAI 8347, pp. 177-188.

That is all for today. More data mining videos will be posted soon!
