چکیده
Urban road intersection bottleneck has become an important factor in causing traffic delay and restricting efficiency. It is essential to explore the prediction of operating performance at intersections real-time formulate corresponding strategies alleviate delay. However, because sophisticated condition, it difficult capture Spatio-temporal features by traditional data methods. The development big technology deep learning model provides us a good chance address this challenge. Therefore, paper proposes multi-task fusion (MFDL) based on massive floating car effectively predict passing time speed over different estimation granularity. Moreover, grid fuzzy C-means (FCM) clustering method are developed identify area derive set key parameters from data. In order validate effectiveness proposed model, ten Beijing with sampling rate 3s adopted for training test process. experiment result shows that MFDL enables topology feature state efficiently. Compared method, best performance. interplay between these two targeted variables can significantly improve accuracy Thereby, predicts operation provide valuable insights managers intersection’s

A Deep Learning Framework for Short-term Power Load Forecasting
The scheduling and operation of power system becomes prominently complex and uncertain, especially with the penetration of distributed power. Load forecasting matters to the effective operation of power system. This paper proposes a novel deep learning framework to forecast the short-term grid load. First, the load data is processed by Box-Cox transformation, and two parameters (electricity pri...

Deep Model Based Transfer and Multi-Task Learning Deep Model Based Transfer and Multi-Task Learning for Biological Image Analysis
A central theme in learning from image data is to develop appropriate representations for the specific task at hand. Traditional methods used handcrafted local features combined with high-level image representations to generate image-level representations. Thus, a practical challenge is to determine what features are appropriate for specific tasks. For example, in the study of gene expression p...
