A quantitative study of Web cache replacement strategies using simulation

Sam Romano, Hala ElAarag
2011 Simulation (San Diego, Calif.)  
The cache replacement strategies implemented in Squid, a widely used proxy cache software, are no longer considered 'good enough' today. Squid's default strategy is Least Recently Used.  ...  In this paper, we focus on the cache replacement problem with respect to proxy servers.  ...  However, it may be decreasing network latency as it may be giving preference to objects that have high latency/network costs, which is a factor the cost models use.  ...

A relevance-scalability-interpretability tradeoff with temporally evolving user personas [article]

Snigdha Panigrahi, Nadia Fawaz
2017 arXiv   pre-print
Finally, we show a trade-off between an indispensable trio of guarantees, relevance-scalability-interpretability by using summary information from personas in a CTR (Click through rate) predictive model  ...  The current work characterizes the users of a VoD streaming space through user-personas based on a tenure timeline and temporal behavioral features in the absence of explicit user profiles.  ...  Recency of Content consumed: We obtain 3 genre clusters based on the count matrices binned as per release year of content to observe characterizations for recency of content.  ...

Applying Machine Learning Techniques for Caching in Edge Networks: A Comprehensive Survey [article]

Junaid Shuja, Kashif Bilal, Waleed Alasmary, Hassan Sinky, Eisa Alanazi
2020 arXiv   pre-print
In next generation edge networks, i.e., 5G and beyond 5G, machine learning techniques can be applied to predict content popularity based on user preferences, cluster users based on similar content interests  ...  User mobility, preferences, and content popularity are the dominant dynamic features of edge networks.  ...  However, the standard recency-based and frequency-based caching algorithms can not be applied to wireless edge networks due to its non-deterministic properties [110] .  ...

Shuo Wang, Xing Zhang, Yan Zhang, Lin Wang, Juwo YANG, Wenbo Wang
2017 IEEE Access  
The traditional centralized network architecture cannot accommodate such user demands due to heavy burden on the backhaul links and long latency.  ...  Therefore, new architectures which bring network functions and contents to the network edge are proposed, i.e., mobile edge computing and caching.  ...  (LFU) • Least recently used (LRU) • most popular video (MPV) User Preference Based Policies [82] • Considering local content popularity • User's preference toward specific video categories  ...

An endogenous distributed model of ordering in serial recall

2002 Psychonomic Bulletin & Review  
Although other serial order models could be extended to make latency predictions-for example, in OSCAR, latency predictions could be based on the similarity between the correct response and the model's  ...  Finally, response suppression has been used to model recency (e.g., Lewandowsky, 1999; Lewandowsky & Li, 1994; Lewandowsky & Murdock, 1989) .  ...  This was omitted here because the random cues used in SOB contain no relevant information.  ...

Traveling economically through memory space: Characterizing output order in memory for serial order

Stephan Lewandowsky, Gordon D. A. Brown, Jacqueline L. Thomas
2009 Memory & Cognition  
Similar distance effects in recognition, using latency rather than accuracy as the primary measure, have been obtained by McKoon and Ratcliff (1980; see also Lewandowsky, 1986 ).  ...  Tan and Ward (2007) reported the same preference using a similar unconstrained task but involving written recall, suggesting that recency-first report is a general characteristic of immediate tests.  ...  The focus on the first two output positions is particularly warranted in the present experiment, in which the use of short lists rapidly constrained the range of available lags across output positions.  ...
