■ An Active Learning Framework Incorporating User Input For Mining Urban Data
An Active Learning Framework Incorporating User Input For Mining Urban Data, Nikolaos Zygouras, Nikolaos Panagiotou, Nikos Zacheilas, Ioannis Boutsis, Vana Kalogeraki, Dimitrios Gunopulos , UrbComp 2016, San Francisco, California, USA, August 2016
In this work we describe a novel active learning framework for training a supervised model, for traffic event detection, considering both time and budget constraints. The proposed method, carefully selects informative instances to be annotated and addresses this way the label scarcity problem that is present on both of the VaVeL project use cases.

■ Revealing Patterns and Trends of Mass Mobility through Spatial and Temporal Abstraction of Origin-Destination Movement Data
Gennady Andrienko, Natalia Andrienko, Georg Fuchs, and Jo Wood Revealing Patterns and Trends of Mass Mobility through Spatial and Temporal Abstraction of Origin-Destination Movement Data IEEE Transactions on Visualization and Computer Graphics, 2017, vol. 23(9), pp.2120-2136
This paper addresses an important problem of analysing origin-destination (OD) movement data. The paper presents an approach facilitating exploration of long-term flow data by means of spatial and temporal abstraction. It involves a special way of data aggregation, which allows representing spatial situations by diagram maps instead of flow maps, thus reducing the intersections and occlusions pertaining to flow maps.

This paper introduces a novel technique that automatically builds a digital map from a GPS trajectory collection. The same technique is able to update an existing map in the case of a change in the road network handling this way the data veracity problem, that is one of the major VaVeL goals, for the digital map case.

■ Matrix Completion under Interval Uncertainty
Mareček, J., Richtárik, P., & Takáč, M. (2017). Matrix completion under interval uncertainty. European Journal of Operational Research, 256(1), 35-43.
Matrix completion under interval uncertainty can be cast as matrix completion with element-wise box constraints. We show that alternating-direction parallel coordinate-descent method for the problem outperforms any other known method on a benchmark in image in-painting in terms of signal-to-noise ratio, and that it provides high-quality solutions for an instance of collaborative filtering with 100,198,805 recommendations within 5 minutes.
