Data Set Information:
Past Usage:
(a) R?gnvaldsson, You and Garwicz (2015) 'State of the art prediction of HIV-1 protease
cleavage sites', Bioinformatics, vol 31 (8), pp. 1204-1210.
- Discusses the characteristics of the four data sets.
- It is shown that a linear SVM with standard orthogonal encoding is the best
predictor when tested across data sets. The AUC (Area Under the ROC Curve)
values are listed below:
Test data 746 1625 Schilling Impens
Train data
746 - 0.982 0.870 0.833
1625 0.981 - 0.855 0.811
Schilling 0.933 0.935 - 0.911
Impens 0.902 0.894 0.929 -
The 746 and 1625 data sets share many patterns.

Interactome'. Proteins: Structure, Function, and Bioinformatics, 68, 305a€“312.
Introduced the 1625 data set and used rough set theory on it.
Note: the 1625 data set used by Kontijevskis et al. is not identical to the 1625 data
set here, there is one octamer that has a different label (same octamer as for the
746 data set).

of Human Immunodeficiency Virus Type 1 Protease'. Journal of Virology, 79, 12477a€“12486.
Introduced the 746 data set and explored linear classifiers plus representations
based on amino acid properties.
Note: the 746 data set used by You et al. is not identical to the 746 data
set here, there is one octamer that has a different label (same octamer as for the
1625 data set).
Other relevant information
The data sets have appeared in earlier publications (see references in R?gnvaldsson et al. 2015).
However, corrections have been made to them here.
Details on references where data has been collected are provided for the 746 and the 1625 data set.
The origins of the Schilling data and the Impens data are described in the paper R?gnvaldsson et al., 2015.
Attribute Information:
Each attribute is a letter denoting an amino acid. G (Glycine, Gly); P (Proline, Pro); A (Alanine, Ala); V (Valine, Val); L (Leucine, Leu); I (Isoleucine, Ile); M (Methionine, Met); C (Cysteine, Cys); F (Phenylalanine, Phe); Y (Tyrosine, Tyr); W (Tryptophan, Trp); H (Histidine, His); K (Lysine, Lys); R (Arginine, Arg); Q (Glutamine, Gln); N (Asparagine, Asn); E (Glutamic Acid, Glu); D (Aspartic Acid, Asp); S (Serine, Ser); T (Threonine, Thr). The output denotes cleaved (+1) or not cleaved (-1).

Citation Request:
It is appreciated if you can refer to the paper by R?gnvaldsson et al. (2015) if you use the data created for this paper. However, other references (also by other researchers) are provided there if you chose to only use a subpart of the data.
