Is my Driver Observation Model Overconfident? Input-guided Calibration Networks for Reliable and Interpretable Confidence Estimates

no code implementations10 Apr 2022 Alina Roitberg, Kunyu Peng, David Schneider, Kailun Yang, Marios Koulakis, Manuel Martinez, Rainer Stiefelhagen

In this work, we for the first time examine how well the confidence values of modern driver observation models indeed match the probability of the correct outcome and show that raw neural network-based approaches tend to significantly overestimate their prediction quality.

Uncertainty-sensitive Activity Recognition: a Reliability Benchmark and the CARING Models

no code implementations2 Jan 2021 Alina Roitberg, Monica Haurilet, Manuel Martinez, Rainer Stiefelhagen

While temperature scaling alone drastically improves the reliability of the confidence values, our CARING method consistently leads to the best uncertainty estimates in all benchmark settings.

Detective: An Attentive Recurrent Model for Sparse Object Detection

no code implementations25 Apr 2020 Amine Kechaou, Manuel Martinez, Monica Haurilet, Rainer Stiefelhagen

At each iteration, our decoder focuses on the relevant parts of the image using an attention mechanism, and then estimates the object's class and the bounding box coordinates.

Taming the Cross Entropy Loss

no code implementations11 Oct 2018 Manuel Martinez, Rainer Stiefelhagen

We present the Tamed Cross Entropy (TCE) loss function, a robust derivative of the standard Cross Entropy (CE) loss used in deep learning for classification tasks.

Relaxed Earth Mover's Distances for Chain- and Tree-connected Spaces and their use as a Loss Function in Deep Learning

no code implementations22 Nov 2016 Manuel Martinez, Monica Haurilet, Ziad Al-Halah, Makarand Tapaswi, Rainer Stiefelhagen

The Earth Mover's Distance (EMD) computes the optimal cost of transforming one distribution into another, given a known transport metric between them.
