  1. RAPARE: A Generic Strategy for Cold-Start Rating Prediction Problem

  2. In Recent years, recommender system is one of indispensable components in many e-commerce websites. One of the major challenges that largely remains open is the cold-start problemon your Google Drive and will be able to edit, add or delete slides. Our proposed strategy can be instantiated into existing methods I recommender systems. RAPARE strategy We instantiate the proposed generic RAPARE strategy on both matrix factorization based (RAPARE-MF) and neighborhood based (RAPARE-KNN) collaborative filtering, together with algorithms to solve them. We present the algorithm analysis for RAPARE strategy and its instantiations on aspects of effectiveness and efficiency. Abstract

  3. DISADVANTAGE: The inactive list of products will get eliminated. The product vendor and the seller will get Benefited as every product is recommended uniformly

  4. ARCHITECTURE Let’s start

  5. Improve the evaluations on five real data sets show that our approach outperforms several bench marks collaborative filtering and online updating methods in terms of prediction accuracy and RAPARE-MF can provide fast recommendations with linear scalability. FUTURE WORK
