• Abstract: Deep time series models often suffer from reliability issues due to their tendency to rely on spurious correlations, leading to incorrect predictions. To mitigate such shortcuts and prevent "Clever-Hans" moments in time series models, we introduce Right on Time (RioT), a novel method that enables interacting with model explanations across both the time and frequency domains. By incorporating feedback on explanations in both domains, RioT constrains the model, steering it away from annotated spurious correlations. This dual-domain interaction strategy is crucial for effectively addressing shortcuts in time series datasets. We empirically demonstrate the effectiveness of RioT in guiding models toward more reliable decision-making across popular time series classification and forecasting datasets, as well as our newly recorded dataset with naturally occuring shortcuts, P2S, collected from a real mechanical production line.

  Time series forecasting has been a widely explored task of great importance in many applications. It is common that real-world time series data are recorded in a short time period, which results in a big gap between the deep model and the limited and noisy time series. We propose to address the time series forecasting problem with generative modeling and propose a bidirectional variational auto-encoder equipped with diffusion, denoise, and disentanglement.

• Towards Spatio-Temporal Aware Traffic Time Series Forecasting--Full Version [37.09531298150374]
  Traffic series forecasting is challenging due to complex time series patterns for the same time series patterns may vary across time, where, for example, there exist periods across a day showing stronger temporal correlations. Such-temporal models employ a shared parameter space irrespective of the time locations and the time periods and they assume that the temporal correlations are similar across locations and do not always hold across time which may not always be the case. We propose a framework that aims at turning ICD-temporal aware models to encode sub-temporal models.
