The mapping of categorical variables into numerical values is common in machine learning classification problems. This type frequently performed a relatively arbitrary manner. We present series four assumptions (tested numerically) regarding these mappings the context protein using amino acid information. assumption involves problems without need to use approaches such as natural language proce...

a thorough recognition of the nature and duties of the genes is based upon having adequate information about the proteins. however, the proteomic projects follow a slow trend; therefore, solving the protein-related problems has become as one of the most important challenges in bio-informatics. consequently, the presence of tools which can enhance the structural recognition, classification, and ...

Protein sequence classification involves feature selection for accurate classification. Popular protein sequence classification techniques involve extraction of specific features from the sequences. Researchers apply some well-known classification techniques like neural networks, Genetic algorithm, Fuzzy ARTMAP, Rough Set Classifier etc for accurate classification. This paper presents a review ...

Proteomics is an attempt to describe or explain biological state and qualitative and quantitative changes of protein content of cells and extracellular biological materials under different conditions to further understand biological processes. Protein-Protein interaction prediction and classification is a very important task. Prediction and classification of protein-protein interactions can hel...

SCOPPI, the structural classification of protein-protein interfaces, is a comprehensive database that classifies and annotates domain interactions derived from all known protein structures. SCOPPI applies SCOP domain definitions and a distance criterion to determine inter-domain interfaces. Using a novel method based on multiple sequence and structural alignments of SCOP families, SCOPPI presen...

Protein structural models provide essential information for the research on proteinprotein interactions. In this dissertation, we describe two projects on the analysis of protein interactions using structural information. The focus of the first is to characterize and classify different types of interactions. We discriminate between biological obligate and biological non-obligate interactions, a...

We address the problem of multi-way relation classification, applied to identification of the interactions between proteins in bioscience text. A major impediment to such work is the acquisition of appropriately labeled training data; for our experiments we have identified a database that serves as a proxy for training data. We use two graphical models and a neural net for the classification of...

Proteins form a very important part of a living cell. The biological functions are carried out by the proteins within the cell by interacting with other proteins in other cells. This is called protein-protein interaction. Protein-Protein Interactions are very important in understanding the diseases and finding their cause. It can also provide the basis for new therapeutic approaches. A number o...
