On the Reduction of Biases in Big Data Sets for the Detection of Irregular Power Usage

no code implementations17 Jan 2018 Patrick Glauner, Radu State, Petko Valtchev, Diogo Duarte

Our models have the potential to generate significant economic value in a real world application, as they are being deployed in a commercial software for the detection of irregular power usage.

Identifying Irregular Power Usage by Turning Predictions into Holographic Spatial Visualizations

no code implementations9 Sep 2017 Patrick Glauner, Niklas Dahringer, Oleksandr Puhachov, Jorge Augusto Meira, Petko Valtchev, Radu State, Diogo Duarte

Second, in order to allow human experts to feed their knowledge in the decision loop, we propose a method for visualizing prediction results at various granularity levels in a spatial hologram.

Neighborhood Features Help Detecting Non-Technical Losses in Big Data Sets

no code implementations4 Jul 2016 Patrick Glauner, Jorge Meira, Lautaro Dolberg, Radu State, Franck Bettinger, Yves Rangoni, Diogo Duarte

Using the neighborhood features instead of only analyzing the time series has resulted in appreciable results for Big Data sets for varying NTL proportions of 1%-90%.
