Calibrated Perception Uncertainty Across Objects and Regions in Bird's-Eye-View

no code implementations8 Nov 2022 Markus Kängsepp, Meelis Kull

In driving scenarios with poor visibility or occlusions, it is important that the autonomous vehicle would take into account all the uncertainties when making driving decisions, including choice of a safe speed.

On the Usefulness of the Fit-on-the-Test View on Evaluating Calibration of Classifiers

1 code implementation16 Mar 2022 Markus Kängsepp, Kaspar Valk, Meelis Kull

This motivates the fit-on-the-test view on evaluation: first, approximate a calibration map on the test data, and second, quantify its distance from the identity.

Cross-model Fairness: Empirical Study of Fairness and Ethics Under Model Multiplicity

2 code implementations14 Mar 2022 Kacper Sokol, Meelis Kull, Jeffrey Chan, Flora Dilys Salim

While data-driven predictive models are a strictly technological construct, they may operate within a social context in which benign engineering choices entail implicit, indirect and unexpected real-life consequences.

Shift Happens: Adjusting Classifiers

no code implementations3 Nov 2021 Theodore James Thibault Heiser, Mari-Liis Allikivi, Meelis Kull

Minimizing expected loss measured by a proper scoring rule, such as Brier score or log-loss (cross-entropy), is a common objective while training a probabilistic classifier.

Correlated daily time series and forecasting in the M4 competition

1 code implementation28 Mar 2020 Anti Ingel, Novin Shahroudi, Markus Kängsepp, Andre Tättar, Viacheslav Komisarenko, Meelis Kull

We participated in the M4 competition for time series forecasting and describe here our methods for forecasting daily time series.

Non-Parametric Calibration of Probabilistic Regression

no code implementations20 Jun 2018 Hao Song, Meelis Kull, Peter Flach

The task of calibration is to retrospectively adjust the outputs from a machine learning model to provide better probability estimates on the target variable.

Probabilistic Sensor Fusion for Ambient Assisted Living

no code implementations4 Feb 2017 Tom Diethe, Niall Twomey, Meelis Kull, Peter Flach, Ian Craddock

There is a widely-accepted need to revise current forms of health-care provision, with particular interest in sensing systems in the home.

Precision-Recall-Gain Curves: PR Analysis Done Right

1 code implementation NeurIPS 2015 Peter Flach, Meelis Kull

Precision-Recall analysis abounds in applications of binary classification where true negatives do not add value and hence should not affect assessment of the classifier's performance.
