Bayesian Active Learning for Censored Regression

no code implementations19 Feb 2024 Frederik Boe Hüttel, Christoffer Riis, Filipe Rodrigues, Francisco Câmara Pereira

To address this, we derive the entropy and the mutual information for censored distributions and derive the BALD objective for active learning in censored regression ($\mathcal{C}$-BALD).

Deep Evidential Learning for Bayesian Quantile Regression

no code implementations21 Aug 2023 Frederik Boe Hüttel, Filipe Rodrigues, Francisco Câmara Pereira

The proposed method is based on evidential learning, which allows the model to capture aleatoric and epistemic uncertainty with a single deterministic forward-pass model.

Applied metamodelling for ATM performance simulations

no code implementations7 Aug 2023 Christoffer Riis, Francisco N. Antunes, Tatjana Bolić, Gérald Gurtner, Andrew Cook, Carlos Lima Azevedo, Francisco Câmara Pereira

Lastly, we discuss two practical approaches for reducing the computational burden of the metamodelling further: we introduce a stopping criterion for active learning based on the inherent uncertainty of the metamodel, and we show how the simulations used for the metamodel can be reused across key performance indicators, thus decreasing the overall number of simulations needed.

Mind the Gap: Modelling Difference Between Censored and Uncensored Electric Vehicle Charging Demand

1 code implementation16 Jan 2023 Frederik Boe Hüttel, Filipe Rodrigues, Francisco Câmara Pereira

As a result, machine learning models that rely on these observed records for forecasting charging demand may be limited in their application in future infrastructure expansion and supply management, as they do not estimate the true demand for charging.

Bayesian Active Learning with Fully Bayesian Gaussian Processes

2 code implementations20 May 2022 Christoffer Riis, Francisco Antunes, Frederik Boe Hüttel, Carlos Lima Azevedo, Francisco Câmara Pereira

In active learning, where labeled data is scarce or difficult to obtain, neglecting this trade-off can cause inefficient and non-optimal querying, leading to unnecessary data labeling.
