Dialogue segmentation plays a crucial role in various dialogue modeling tasks. Semantic coherence-based methods are a major trend, but previous methods have tended to take fixed-size units in assessing semantic coherence, which may suffer from semantic loss or noise introduction, thus obtaining inaccurate coherence scores. In this paper, we propose a simple but effective approach for dynamically assessing semantic coherence, which can improve the accuracy of coherence scoring by dynamically expanding the assessment unit from a single utterance to a semantically related context. Experimental results on three benchmark datasets in English and Chinese demonstrate that our proposal can achieve competitive performance over strong baselines.

Withthe expansion of renewables in the electricity mix, power grid variability will increase;hence, the system needs to be robust to guarantee its security. To anticipate the design of new tools and processes, Transmission System Operators (TSOs) must conduct analyses to simulate the future operation of power systems. then, these simulations are used as inputs in decision-making processes. In this context, we investigate using deep learning models to generate energy production and load forecast trajectories. We adapt autoregressive networks and normalizing flows to capture the spatiotemporal correlations in these multivariate time series, demonstrating their effectiveness against the current copula-based statistical approach. We conduct extensive experiments on the French TSO RTE wind forecast data and compare the different models with ad hoc evaluation metrics for time series generation.
