An implementation of this "logical analysis of data" (LAD) methodology is described, along with the results of numerical experiments demonstrating the classification performance of LAD in comparison with the reported results of other procedures. Expand

- 12 September 1995
A method for predicting protein folding class based on global protein chain description and a voting process, achieved by a computer-simulated neural network trained on a data base consisting of 83 folding classes, shows that proteins were assigned to the correct class with an average accuracy.

Reconstruction of ancient molecular phylogeny.
Under the assumption that differences among gene trees can be explained by gene duplications, and consequent losses, it is developed a method to obtain the global phylogeny minimizing the total number of postulated duplications and losses and to trace back such individual gene duplication to global genome duplications.

Recognition of a protein fold in the context of the SCOP classification
A computational method has been developed for the assignment of a protein sequence to a folding class in the SCOP, using global descriptors of a primary protein sequence in terms of the physical, chemical, and structural properties of the constituent amino acids. Expand
Support Vector Machines for Classification
In many real-life situations we want to be able to assign an object to one of several categories based on some of its characteristics. For example, based on the results of several medical tests we… Expand
Recognition of a protein fold in the context of the Structural Classification of Proteins (SCOP) classification.
A computational method has been developed for the assignment of a protein sequence to a folding class in the Structural Classification of Proteins (SCOP). This method uses global descriptors of a… Expand
A Biologically Consistent Model for Comparing Molecular Phylogenies
The model is employed for embedding a phylogeny tree into another one via the so-called duplication/speciation principle requiring that the gene duplicated evolves in such a way that any of the contemporary species involved bears only one of the gene copies diverged. Expand
A Biologically Meaningful Model for Comparing Molecular Phylogenies
The model is employed for embedding a plylogeny tree into another one via so called Duplication/Speciation principle requiring that the gene duplicated evolves in such a way that any of the contemporary species involved bears only one of the gene copies diverged. Expand
Protein Folding Class Predictor for SCOP: Approach Based on Global Descriptors
This work demonstrates new techniques developed for the prediction of protein folding class in the context of the most comprehensive Structural Classification of Proteins (SCOP) in terms of the physical, chemical and structural properties of its constituent amino acids. Expand
