| 1 | CO2 and SO2 emission characteristics of the whole process industry chain of coal processing and utilization in China显示文摘The total coal consumption in China is on the rise.The characteristics of CO2 and SO2 emissions in the whole process of coal processing and utilization in China are worthy of study.Based on the five links of the whole process of coal production and utilization,including coal production,raw coal processing,logistics and transportation,conversion and utilization and resource utilization,this paper summarized and analyzed the energy consumption and pollutant emission sources of these five links,combined with the US Environmental Protection Agency’s AP-42 method and IPCC method,to calculate total pollutant discharge and emission factors,where the emission factors were corrected by conversion efficiency.At the same time,uncertainty analysis is performed about CO2 and SO2 emissions.The results showed that CO2 emissions were 3.657 billion tons,and emission reductions were 61 million tons,and SO2 emissions were 4,844,500 tons,and emission reductions were 10.3595 million tons in 2015. | Tao Zhu Ruonan Wang Nengjing Yi Wenfeng Niu Lifeng Wang Zeyu Xue | 2020 | International Journal of Coal Science & Technology2020，7，1： | 8 |

| 12 | Soft Decision Tree for Regression显示文摘Decision tree(DT)plays an important role in pattern recognition and machine learning,which is widely used for regression tasks because of its natural interpretability.Nevertheless,the traditional decision tree is constructed by recursive Boolean division.The discrete decision-making process in DT makes it non-differentiable,and causes the problem of hard decision boundary.To solve this problem,a probability distribution model—Staired-Sigmoid is proposed in this paper.The Staired-Sigmoid model is used to differentiate the decision-making process,by which the samples can be assigned to two sub-trees more finely.Based on Staired-Sigmoid,we further propose the soft decision tree(SDT)for regression tasks,where the samples are assigned to different sub-nodes according to a continuous probability distribution.This process is differentiable,and all parameters in SDT can be optimized by gradient descent algorithms.Owing to its constructing rules,SDT is more stable than decision tree,and it is easier to overcome the problem of overfitting.We validate SDT on several datasets obtained from UCI.Experiments demonstrate that SDT achieves better performance than decision tree,and it significantly alleviates the overfitting. | Nengjing GUO Jianfeng HUANG | 2022 | Journal of Systems Science and Information2022，10，5： | 0 |
