The PSP Approach for Mining
نویسندگان
چکیده
In this paper, we present an approach, called PSP, for mining sequential patterns embedded in a database. Close to the problem of discovering association rules, mining sequential patterns requires handling time constraints. Originally introduced in 3], the issue is addressed by the GSP approach 10]. Our proposal resumes the general principles of GSP but it makes use of a diierent intermediary data structure which is proved to be more eecient than in GSP.

A Study on PSP Algorithm for Automatic Generation of Internet Traffic Signature
In this paper we propose an algorithm approach, so called PSP (Prefix tree for Sequential Patterns) for automatic Internet traffic signatures generation. In presenting PSP algorithm approach, we basically refer it to the GSP (Generalized Sequential Pattern), since PSP algorithm is an extension of GSP algorithm. Actually the two algorithms were originally proposed to deal with data mining proble...
متن کاملUsing factorization machines for student modeling
Predicting student performance (PSP), one of the task in Student Modeling, has been taken into account by educational data mining community recently. Previous works show that good results can be achieved by casting the PSP to rating prediction task in recommender systems, where students, tasks and performance scores are mapped to users, items and ratings respectively, and thus, matrix factoriza...

Introduction & Objective: Diagnosis of periodontal osseous lesions is very important in deter-mining prognosis, treatment plan and maintenance in the long term. This diagnosis can be achieved by using radiography. The aim of this study is to compare accuracy of E speed films, bitewing PSP, panoramic PSP and CCD for identifying the extent of destruction of alveolar bone in chronic periodontiti...

Predicting student performance (PSP) is an important task in educational data mining, where we can give the students early feedbacks to help them improving their study results. A good and reliable model which accurately predicts the student performance may replace the current standardized tests, thus, reducing the pressure on teaching and learning for examinations as well as saving a lot of tim...
متن کاملData Mining in Proteomics with Learning Classifier Systems
The era of data mining has provided renewed effort in the research of certain areas of biology that for their difficulty and lack of knowledge were and are still considered unsolved problems. One such problem, which is one of the fundamental open problems in computational biology is the prediction of the 3D structure of proteins, or protein structure prediction (PSP). The human experts, with th...
