The key challenge for learning a fine-grained sketch-based image retrieval (FG-SBIR) model is to bridge the domain gap between photo and sketch. Existing models learn a deep joint embedding space with discriminative losses where a photo and a sketch can be compared. In this paper, we propose a novel discriminative-generative hybrid model by introducing a generative task of cross-domain image sy...

We introduce the notion of fault tolerant mechanism design, which extends the standard game theoretic framework of mechanism design to allow for uncertainty about execution. Specifically, we define the problem of task allocation in which the private information of the agents is not only their costs to attempt the tasks, but also their probabilities of failure. For several different instances of...

Aligning innovation processes in healthcare with health system demands is a societal objective, not always achieved. In line with earlier contributions, Lehoux et al outline priorities for research, public communication, and policy action to achieve this objective. We endorse setting these priorities, while also highlighting a ‘commitment gap’ in collectively addressing system-level challenges....

Does task significance increase job performance? Correlational designs and confounded manipulations have prevented researchers from assessing the causal impact of task significance on job performance. To address this gap, 3 field experiments examined the performance effects, relational mechanisms, and boundary conditions of task significance. In Experiment 1, fundraising callers who received a ...

The Context Aware Recommender Systems aim to combine a set of technologies and knowledge about the user context in order to deliver the most appropriate information to the user need at just the right time. It is called Proactive Recommendation. In this paper, we propose an approach for context-aware proactive recommendation in a mobile environment that aims at providing users with relevant info...

As a partial requirement of the development of an information system for the UK fire and rescue services, this paper describes the development and application of a protocol capable of capturing the information requirements of fire and rescue first responders. After evaluating the existing techniques commonly used in difficult decision-making environments, a Goal Directed Information Analysis (G...

A qualitative explorative evaluation considered the effects of six visualization interfaces of sales forecasting systems on 60 university students. The study builds on earlier research from the domain of business forecasting in supply chain industries. The evaluation generates exemplar interfaces derived from the theoretical framework and task analysis of interviews with 20 expert users and des...

Cartograms are maps in which areas of geographic regions (countries, states) appear in proportion to some variable of interest (population, income). Despite the popularity of cartograms and the large number of cartogram variants, there are few studies evaluating the effectiveness of cartograms in conveying information. In order to design cartograms as a useful visualization tool and to be able ...

Throughout the 1990s, we have witnessed the burgeoning interest and rapidly advancing technologies in the "eld of information visualization (Card, Mackinlay & Shneiderman, 1999; Chen, 1999; Ware, 2000). This "eld has captured the imagination of researchers and practitioners from a wide range of disciplines all over the world. Increasingly powerful and visually appealing information visualizatio...
