Efficient User Grouping for Hybrid Beamforming in Single Carrier Wideband Massive MIMO Channels
, 2021 In this paper, three types of user grouping algorithms in which our own performance metric is utilized are investigated for single carrier downlink wideband spatially correlated massive MIMO channels by using hybrid beamforming structure motivated by the

This work explores the behaviour of User Groups -- the ad hoc, geographically-based, socio-technical networks formed by users of particular software technologies as networking, self-help and mutual learning spaces. We compare these networks to the discussion lists, (general) social networks and communities of practice which these users also inhabit. We

Autonomous characters in virtual environmentshave the potential to improve the interaction experience of users, specially, their social experience.This effect is driven by the interactions occurring between users and the autonomous characters, that in certain scenarios can be in the context of a group.However, for these group interactions to be ...

Interactive User Group Analysis
Proceedings of the 24th ACM International on Conference on Information and Knowledge Management, 2015User data is becoming increasingly available in multiple domains ranging from phone usage traces to data on the social Web. The analysis of user data is appealing to scientists who work on population studies, recommendations, and large-scale data analytics. We argue for the need for an interactive analysis to understand the multiple facets of user data

Crowdsourcing with Diverse Groups of Users
Proceedings of the 20th International Workshop on the Web and Databases, 2017When crowdsourcing to achieve some goal, or to gather information, there is a distinct advantage to choosing a diverse team of users. Past research has shown the advantages of diversity in the workplace, as team members bring different perspectives and points of view.

The “VIM” Users organization was established in 1965 and subsequently incorporated in 1970. The letters “VIM”, as suggested by Professor Max Goldstein of NYU, were originally meant to represent 6000 in Pseudo-Roman numerals. To qualify for membership, an organization must have installed or on order a CDC 6000, 7000, CYBER 70 or CYBER 170 series ...

IEEE Transactions on Communications, 2013
A generalized version of orthogonal frequency division multiplexing interleave division multiple access (OFDM-IDMA) referred to as grouped OFDM-IDMA (G-OFDM-IDMA) is introduced in this paper. By dividing users into groups and transmitting each group's data only on some (as opposed to all) subcarriers, G-OFDM-IDMA can have much lower decoding complexity

Music recommendations for groups of users
Proceedings of the 2013 ACM international workshop on Immersive media experiences, 2013This paper presents an algorithm capable of providing meaningful recommendations to small sets of users. We consider not only rating patterns, bias tendencies, and temporal fluctuations, but also group-leaders. The approach here presented intends to bring a fresh new look over group recommendations, making use of latent factor space to identify groups ...
