Calibrating Bayesian UNet++ for Sub-Seasonal Forecasting

no code implementations25 Mar 2024 Busra Asan, Abdullah Akgül, Alper Unal, Melih Kandemir, Gozde Unal

Seasonal forecasting is a crucial task when it comes to detecting the extreme heat and colds that occur due to climate change.

BOF-UCB: A Bayesian-Optimistic Frequentist Algorithm for Non-Stationary Contextual Bandits

no code implementations7 Jul 2023 Nicklas Werge, Abdullah Akgül, Melih Kandemir

We propose a novel Bayesian-Optimistic Frequentist Upper Confidence Bound (BOF-UCB) algorithm for stochastic contextual linear bandits in non-stationary environments.

Continual Learning of Multi-modal Dynamics with External Memory

no code implementations2 Mar 2022 Abdullah Akgül, Gozde Unal, Melih Kandemir

We study the problem of fitting a model to a dynamical environment when new modes of behavior emerge sequentially.

Evidential Turing Processes

2 code implementations ICLR 2022 Melih Kandemir, Abdullah Akgül, Manuel Haussmann, Gozde Unal

A probabilistic classifier with reliable predictive uncertainties i) fits successfully to the target domain data, ii) provides calibrated class probabilities in difficult regions of the target domain (e. g.\ class overlap), and iii) accurately identifies queries coming out of the target domain and rejects them.
