Conformative Filtering for Implicit Feedback Data [chapter]

Farhan Khawar, Nevin L. Zhang
2019 Lecture Notes in Computer Science  
We perform multidimensional clustering on implicit feedback data using hierarchical latent tree analysis (HLTA) to identify user 'tastes' groups and make recommendations for a user based on her memberships  ...  Implicit feedback is the simplest form of user feedback that can be used for item recommendation. It is easy to collect and is domain independent. However, there is a lack of negative examples.  ...  Acknowledgements We thank Peixian Chen and Zhourong Chen for valuable discussions. Research on this article was supported by Hong Kong Research Grants Council under grants 16202515 and 16212516.  ...

A Comparative Study of Matrix Factorization and Random Walk with Restart in Recommender Systems [article]

Haekyu Park, Jinhong Jung, U Kang
2017 arXiv   pre-print
Between matrix factorization or Random Walk with Restart (RWR), which method works better for recommender systems? Which method handles explicit or implicit feedback data better?  ...  We observe that matrix factorization performs better with explicit feedback ratings while RWR is better with implicit ones.  ...  We recommend items when explicit feedback ratings are given; for example, movie rating data with 1 to 5 scaled "stars" are given. • Implicit feedback.  ...

Learning to Rank for Personalised Fashion Recommender Systems via Implicit Feedback [chapter]

Hai Thanh Nguyen, Thomas Almenningen, Martin Havig, Herman Schistad, Anders Kofod-Petersen, Helge Langseth, Heri Ramampiaro
2014 Lecture Notes in Computer Science  
To avoid potential bias when using explicit user ratings, which are also expensive to obtain, this work approaches fashion recommendations by analysing implicit feedback from users in an app.  ...  Based on these implicit preference scores, we infer the user's ranking of other fashion items by applying different recommendation algorithms.  ...  The success of an implicit feedback system therefore relies on a well-defined strategy for inferring user preferences from implicit feedback data, combining event types into implicit scores, and evaluating  ...
