Project Report An Introduction to Collaborative Filtering
A Collaborative Filtering was successfully implemented using the computer programming language Java to produce recommendations between users such that only similar users were considered. Both Mean Squared Difference (MSD) and Pearson Correlation Coefficient (PCC) were used and evaluations carried out on each. The metric which performed best on the u.data file was PCC with L = 0. Conversely, the...
متن کاملA NOVEL FUZZY-BASED SIMILARITY MEASURE FOR COLLABORATIVE FILTERING TO ALLEVIATE THE SPARSITY PROBLEM
Memory-based collaborative filtering is the most popular approach to build recommender systems. Despite its success in many applications, it still suffers from several major limitations, including data sparsity. Sparse data affect the quality of the user similarity measurement and consequently the quality of the recommender system. In this paper, we propose a novel user similarity measure based...
متن کاملContributions to Collaborative Filtering Research
In this report, I first introduced the three areas that of interest to collaborative filtering researchers are interested in and challenged by, namely: (a) how to solve the sparsity and scalability problems in recommendation systems; (b) how to synthesize variousrapidly develop and test collaborative filtering algorithms; and (c) how to apply collaborative filtering to implicit preference datau...
متن کاملAn Introduction to Quantum Filtering
This paper provides an introduction to quantum filtering theory. An introduction to quantum probability theory is given, focusing on the spectral theorem and the conditional expectation as a least squares estimate, and culminating in the construction of Wiener and Poisson processes on the Fock space. We describe the quantum Itô calculus and its use in the modeling of physical systems. We use bo...
متن کاملQoS-based Web Service Recommendation using Popular-dependent Collaborative Filtering
Since, most of the organizations present their services electronically, the number of functionally-equivalent web services is increasing as well as the number of users that employ those web services. Consequently, plenty of information is generated by the users and the web services that lead to the users be in trouble in finding their appropriate web services. Therefore, it is required to provi...
