A recommender system for efficient discovery of new anomalies in large-scale access logs

  title={A recommender system for efficient discovery of new anomalies in large-scale access logs},
  author={Heju Jiang and Scott Algatt and Parvez Ahammad},
We present a novel, non-standard recommender system for large-scale security policy management(SPM). Our system Helios discovers and recommends unknown and unseen anomalies in large-scale access logs with minimal supervision and no starting information on users and items. Typical recommender systems assume availability of user- and item-related information, but such information is not usually available in access logs. To resolve this problem, we first use discrete categorical labels to… Expand


Item-based top-N recommendation algorithms
This article presents one class of model-based recommendation algorithms that first determines the similarities between the various items and then uses them to identify the set of items to be recommended, and shows that these item-based algorithms are up to two orders of magnitude faster than the traditional user-neighborhood based recommender systems and provide recommendations with comparable or better quality.

Item-based collaborative filtering recommendation algorithms
This paper analyzes item-based collaborative ltering techniques and suggests that item- based algorithms provide dramatically better performance than user-based algorithms, while at the same time providing better quality than the best available userbased algorithms. Expand
Collaborative Filtering for Implicit Feedback Datasets
This work identifies unique properties of implicit feedback datasets and proposes treating the data as indication of positive and negative preference associated with vastly varying confidence levels, which leads to a factor model which is especially tailored for implicit feedback recommenders.

CLiMF: learning to maximize reciprocal rank with collaborative less-is-more filtering
This paper proposes a new CF approach, Collaborative Less-is-More Filtering (CLiMF), where the model parameters are learned by directly maximizing the Mean Reciprocal Rank (MRR), which is a well-known information retrieval metric for measuring the performance of top-k recommendations. Expand
Fab: content-based, collaborative recommendation
It is explained how a hybrid system can incorporate the advantages of both methods while inheriting the disadvantages of neither, and how the particular design of the Fab architecture brings two additional benefits. Expand
The Netflix Recommender System
The motivations behind and approach that Netflix uses to improve the recommendation algorithms are explained, combining A/B testing focused on improving member retention and medium term engagement, as well as offline experimentation using historical member engagement data. Expand Recommendations: Item-to-Item Collaborative Filtering
This work compares three common approaches to solving the recommendation problem: traditional collaborative filtering, cluster models, and search-based methods, and their algorithm, which is called item-to-item collaborative filtering. Expand
Content-boosted collaborative filtering for improved recommendations
This paper presents an elegant and effective framework for combining content and collaboration, which uses a content-based predictor to enhance existing user data, and then provides personalized suggestions through collaborative filtering. Expand
Clustering event logs using iterative partitioning
This paper presents IPLoM (Iterative Partitioning Log Mining), a novel algorithm for the mining of clusters from event logs that outperforms the other algorithms statistically significantly, and is also able to achieve an average F- Measure performance 78% when the closest other algorithm achieves an F-Measure performance of 10%.
