Time series forecasting has played the key role in different industrial, including finance, traffic, energy, and healthcare domains. While existing literatures have designed many sophisticated architectures based on RNNs, GNNs, or Transformers, another kind of approaches multi-layer perceptrons (MLPs) are proposed with simple structure, low complexity, {superior performance}. However, most MLP-based methods suffer from point-wise mappings information bottleneck, which largely hinders...
Multivariate time series (MTS) forecasting has shown great importance in numerous industries. Current state-of-the-art graph neural network (GNN)-based methods usually require both networks (e.g., GCN) and temporal LSTM) to capture inter-series (spatial) dynamics intra-series (temporal) dependencies, respectively. However, the uncertain compatibility of two puts an extra burden on handcrafted model designs. Moreover, separate spatial modeling naturally violates unified spatiotemporal...
Multimodal content, such as mixing text with images, presents significant challenges to rumor detection in social media. Existing multimodal has focused on tokens among spatial and sequential locations for unimodal representation or fusing clues of veracity across modalities. However, they suffer from less discriminative are vulnerable intricate location dependencies the time-consuming fusion tokens. This work makes first attempt at frequency domain, which efficiently transforms features...

Medical time series has been playing a vital role in real-world healthcare systems as valuable information monitoring health conditions of patients. Accurate classification for medical series, e.g., Electrocardiography (ECG) signals, can help early detection and diagnosis. Traditional methods towards rely on handcrafted feature extraction statistical methods; with the recent advancement artificial intelligence, machine learning deep have become more popular. However, existing often fail to...

Modeling complex hierarchical and grouped feature interaction in the multivariate time series data is indispensable to comprehend dynamics predicting future condition. The implicit high-dimensional make forecasting very challenging. Many existing works did not put more emphasis on exploring explicit correlation among multiple data, complicated models are designed capture long- short-range pattern with aid of attention mechanism. In this work, we think that pre-defined graph or general...

Due to the nonstationary nature, distribution of real-world multivariate time series (MTS) changes over time, which is known as drift. Most existing MTS forecasting models greatly suffer from drift and degrade performance time. Existing methods address via adapting latest arrived data or self-correcting per meta knowledge derived future data. Despite their great success in forecasting, these hardly capture intrinsic changes, especially a distributional perspective. Accordingly, we propose...
Both masked image modeling (MIM) and natural language supervision have facilitated the progress of transferable visual pre-training. In this work, we seek synergy between two paradigms study emerging properties when MIM meets supervision. To end, present a novel Reconstruction Language semantic Space (RILS) pre-training framework, in which sentence representations, encoded by text encoder, serve as prototypes to transform vision-only signals into patch-sentence probabilities semantically...
Crowdsourced live streaming (CLS), such as Twitch.tv and Inke.tv, has emerged an important multimedia application in recent years. Video delivery CLS service involves two steps: 1) video uploading-video (i.e., a channel) generated from broadcaster is uploaded to the server, which we call "first mile" network 2) distribution-the then delivered viewers channel. Today's services usually use conventional content solutions address distribution problem, while little attention been paid improve...
While most time series are non-stationary, it is inevitable for models to face the distribution shift issue in forecasting. Existing solutions manipulate statistical measures (usually mean and std.) adjust distribution. However, these operations can be theoretically seen as transformation towards zero frequency component of spectrum which cannot reveal full information would further lead utilization bottleneck normalization, thus hindering forecasting performance. To address this problem, we...
