Uczenie głębokie w prognozowaniu punktowym, probabilistycznym i trajektorii cen energii elektrycznej [Deep learning in point, probabilistic and ensemble forecasting of electricity prices] Grzegorz Marcjasz (ORBI, PWr, Wrocław) This talk will summarize the main results of my PhD thesis, which aims at developing robust, reliable and - when possible - interpretable deep learning-based approaches for short-term point, probabilistic and ensemble forecasting of electricity prices. Approaches that significantly outperform regression-based predictions not only in terms of statistical error measures, but also in terms of economic benefits for entities involved in intraday and day-ahead trading. I will also highlight the importance of following best practices, as robust comparisons and replicability are key to research excellence.
