A Method for Decompensation Prediction in Emergency and Harsh Situations for prediction. The experimental results show that the Bi-LSTM-attention method, combined with eleven essential physiological variables, can be used to predict the decompensation of severe ICUs patients. The AUC-ROC can reach 0.8509. Furthermore, these eleven physiological variables can be easily m

Parallel Variable-Length Motif Discovery in Time Series Using Subsequences Correlation to find time series motifs with variable lengths. We have conducted extensive experiments on public data sets, the results demonstrate that our method can efficiently find variable-length motifs in long time series.

Improved Brain Segmentation Using Pixel Separation and Additional Segmentation Featuresrts in medical imaging to evaluate our segmentation results. We observe that our results are fairly close to the manual reference. Moreover, we observe that our model is 1.2.–2.6. faster than prior models. We conclude that our model is more efficient and accurate in practice for both infant and adul

LOCATE: Locally Anomalous Behavior Change Detection in Behavior Information Sequencevolving the locally anomalous behavior change?in the BIS. Two real-world datasets were used to assess the performance of LOCATE. Experimental results demonstrated that LOCATE?is effective in detecting?locally anomalous behavior change.

Predicting Human Mobility with Self-attention and Feature Interaction in a more efficient and effective way. We evaluate MoveNet with three real-world mobility datasets, and show that MoveNet outperforms the state-of-the-art mobility predictor by around 10% in terms of accuracy, and simultaneously achieves faster convergence and over 4x training speedup.
