Therefore, the use of the LSTM algorithm for load forecast is more effective. The CS algorithm can perform global search better and does not easily fall into local optima. The CS-LSTM forecasting model, where CS algorithm is used to optimize the hyper-parameters of the LSTM model, has a ...

Here’s its secret… First, with its equal-weighting strategy, RSP overweights smaller-cap stocks. The average weighted market cap for a stock in the RSP portfolio is $22.4 billion, well short of the $79 billion for the S&P 500. And small and medium caps outperform large-cap stocks over...

Oil and gas boom puts US on track for energy independence The United States will overtake Saudi Arabia to become the world's biggest oil producer before 2020, and will be energy independent 10 years later, according to a new forecast by the International Energy Agency. ...
Based on Frey and Osborne (2017) automation score, we chose occupations on the low-end of automation (stock investments, surgical teams, air traffic control, news desks, therapist, teacher) and on the high-end of automation (supermarkets, customer service desks, sewage plant, construction site,...
这也是web traffic,m5 forecast,favorite store 这些序列比赛的数据的普遍形式,可以说我们面对的主要的问题形式是这样的。 对这些数据进行建模的时候我们面临最直接的问题就是,使用多少的时间步的历史数据预测未来多少个时间步的未来数据,即时间窗的问题,比如我们就用前一天的数据预测后一天的,那么数据就要变成: ...
In this study, we developed a novel deep learning approach using a 3D U-Net structure with multi-source data to forecast SST in the South China Sea (SCS). SST, sea surface height anomaly (SSHA), and sea surface wind (SSW) were used as input variables. Compared with the convolutional ...
The optimal model weights and bias settings are determined by minimizing the loss function, allowing the model to better correctly forecast the PD. A good optimization strategy may speed up model convergence, improve data feature learning, fine-tune the neural network’s weight and bias parameters,...
