CleanM: An Optimizable Query Language for Unified Scale-Out Data Cleaning

Anastasia Ailamaki, Benjamin Cyrille Damien Gaidioz, Manolis Karpathiotakis, Styliani Asimina Giannakopoulou

Data cleaning has become an indispensable part of data analysis due to the increasing amount of dirty data. Data scientists spend most of their time preparing dirty data before it can be used for data analysis. At the same time, the existing tools that att ...

Fast Robust PCA on Graphs

Pierre Vandergheynst, Gilles Puy, Nathanaël Perraudin, Nauman Shahid, Vasilis Kalofolias

Mining useful clusters from high dimensional data has received significant attention of the computer vision and pattern recognition community in the recent years. Linear and non-linear dimensionality reduction has played an important role to overcome the c ...

Integrating Information Sources for Inland Waters - A New Global Framework for Lakes Modelling and Monitoring

Theo Baracchini

Like islands, lakes are not only unique geographical features, but also ecological concepts on their own. Their exceptional variability has been studied numerous times, yet no unique framework capable of reproducing the wide range of lake dynamics observed ...

Patch-wise denoising of phase fringe patterns based on matrix enhancement

Pramod Rastogi, Rishikesh Dilip Kulkarni

We propose a new approach for the denoising of a phase fringe pattern recorded in an optical interferometric setup. The phase fringe pattern which is generally corrupted by high amount of speckle noise is first converted into an exponential phase field. Th ...

Leader corruption depends on power and testosterone

Samuel Bendahan, John Antonakis

We used incentivized experimental games to manipulate leader power - the number of followers and the discretion leaders had to enforce their will. Leaders had complete autonomy in deciding payouts to themselves and their followers. Although leaders could m ...

Strong Privacy for RFID Systems from Plaintext-Aware Encryption

Serge Vaudenay

Modeling privacy for RFID protocols went through different milestones. One pretty complete model was proposed by Vaudenay at ASIACRYPT 2007. It provides a hierarchy of privacy levels, depending on whether corruption is addressed by the protocol and on whet ...

Multiscale codes in the nervous system: The problem of noise correlations and the ambiguity of periodic scales

Alexander Mathis

Encoding information about continuous variables using noisy computational units is a challenge; nonetheless, asymptotic theory shows that combining multiple periodic scales for coding can be highly precise despite the corrupting influence of noise [Mathis, ...

Participation? I like it! The Impact of Social Digital Media on Political Participation: Evidence from the Brazilian Case

Bilal Farooq

Recent years have seen an increasing scholarly debate on the role of the Internet as a sphere for public political expression and participation. Especially social digital media (SDM) are a phenomenon of interest to many scholars. The capability of SDM to f ...

Model-based Behavioural Tracking and Scale Invariant Features in Omnidirectional Matching

Javier Cruz Mota

Two classical but crucial and unsolved problems in Computer Vision are treated in this thesis: tracking and matching. The first part of the thesis deals with tracking, studying two of its main difficulties: object representation model drift and total occlu ...
