Deep Cosine Metric Learning for Person Re-Identification

5 code implementations2 Dec 2018 Nicolai Wojke, Alex Bewley

Metric learning aims to construct an embedding where two extracted features corresponding to the same identity are likely to be closer than features from different identities.

Dropout Distillation for Efficiently Estimating Model Confidence

no code implementations27 Sep 2018 Corina Gurau, Alex Bewley, Ingmar Posner

We also propose better calibration within the state of the art Faster R-CNN object detection framework and show, using the COCO dataset, that DDN helps train better calibrated object detectors.

Scrutinizing and De-Biasing Intuitive Physics with Neural Stethoscopes

no code implementations14 Jun 2018 Fabian B. Fuchs, Oliver Groth, Adam R. Kosiorek, Alex Bewley, Markus Wulfmeier, Andrea Vedaldi, Ingmar Posner

Conversely, training on an easy dataset where visual cues are positively correlated with stability, the baseline model learns a bias leading to poor performance on a harder dataset.

Meshed Up: Learnt Error Correction in 3D Reconstructions

no code implementations27 Jan 2018 Michael Tanner, Stefan Saftescu, Alex Bewley, Paul Newman

We train a suitably deep network architecture with two 3D meshes: a high-quality laser reconstruction, and a lower quality stereo image reconstruction.
