Metric learning algorithms produce distance metrics that capture the important relationships among data. In this work, we study the connection between metric learning and collaborative filtering. We propose Collaborative Metric Learning (CML) which learns a joint metric space to encode not only users’ preferences but also the user-user and itemitem similarity. The proposed algorithm outperforms...

Automobile sector forms the backbone of manufacturing sector. Vehicle assembly line is important section in automobile plant where repetitive tasks are performed one after another at different workstations. In this thesis, a methodology is proposed to reduce cycle time and time loss due to important factors like equipment failure, shortage of inventory, absenteeism, set-up, material handling, r...

In this paper, we address the task of active learning for linear regression models in collaborative settings. The goal of active learning is to select training points that would allow accurate prediction of test output values. We propose a new active learning criterion that is aimed at directly improving the accuracy of the output value estimation by analyzing the effect of the new training poi...

Drawing upon sociocultural theory of Vygotsky, the current study aims to investigate the effect of dyadic interaction in mixed and matched level proficiency pairings on comprehension and production of request and apology speech acts. The participants were 125 EFL learners who were randomly assigned to control and experimental (interaction) groups. Based on their scores in the pretest including ...

Collaborative crowdsourcing is an emerging paradigm where a set of workers, often with diverse and complementary skills, form groups and work together to complete complex tasks. While crowdsourcing has been used successfully in many applications, collaboration is essential for achieving a high quality outcome for a number of emerging applications such as text translation, citizen journalism and...

Actor: Entity (human or computer) possessing a capability to act intelligently and process specific assignments (activities/tasks). Atomic task: Task that can be handled by an individual actor. CAS: Collective adaptive system. Collaboration system (platform): Information system supporting execution of collaborative processes. Collaborative process (collaboration): Joint effort of a (limited) nu...

Large horizontal displays provide new opportunities to support individual and collaborative activities such as creativity and organizational tasks. We present Interface Currents, a fluid interaction technique designed to support face-to-face collaboration by improving access to and sharing of workspace items. Interface Currents are flexible containers that provide a controllable flow of interfa...

In collaborative scheduling tasks, large surfaces are often crucial. Pin&Play is a novel technology that combines physical and digital information on an interactive pin-board, which can improve collaborative scheduling. In order to explore this and to develop a prototype, we conducted observations of the scheduling of a film festival program. We found that several tasks in the scheduling are de...
