Novel interpretable mechanism of neural networks based on network decoupling method

Frontiers of Engineering Management 2021, Volume 8, Issue 4,   Pages 572-581 doi: 10.1007/s42524-021-0169-x

Abstract: The lack of interpretability of the neural network algorithm has become the bottleneck of its wide application. We propose a general mathematical framework, which couples the complex structure of the system with the nonlinear activation function to explore the decoupled dimension reduction method of high-dimensional system and reveal the calculation mechanism of the neural network. We apply our framework to some network models and a real system of the whole neuron map of Caenorhabditis elegans. Result shows that a simple linear mapping relationship exists between network structure and network behavior in the neural network with high-dimensional and nonlinear characteristics. Our simulation and theoretical results fully demonstrate this interesting phenomenon. Our new interpretation mechanism provides not only the potential mathematical calculation principle of neural network but also an effective way to accurately match and predict human brain or animal activities, which can further expand and enrich the interpretable mechanism of artificial neural network in the future.

Decoupling optimization of integrated energy system based on energy quality character

Shixi MA, Shengnan SUN, Hang WU, Dengji ZHOU, Huisheng ZHANG, Shilie WENG

Frontiers in Energy 2018, Volume 12, Issue 4,   Pages 540-549 doi: 10.1007/s11708-018-0597-4

Abstract:

Connections among multi-energy systems become increasingly closer with the extensive application of various energy equipment such as gas-fired power plants and electricity-driven gas compressor. Therefore, the integrated energy system has attracted much attention. This paper establishes a gas-electricity joint operation model, proposes a system evaluation index based on the energy quality character after considering the grade difference of the energy loss of the subsystem, and finds an optimal scheduling method for integrated energy systems. Besides, according to the typical load characteristics of commercial and residential users, the optimal scheduling analysis is applied to the integrated energy system composed of an IEEE 39 nodes power system and a 10 nodes natural gas system. The results prove the feasibility and effectiveness of the proposed method.

Adjusting Industrial Structure and Reducing Carbon Emission Intensity: International Comparison and Experience Enlightenment

Guo Shiyi, Liu Wenqiang, Zhao Weidong

Strategic Study of CAE 2021, Volume 23, Issue 6,   Pages 22-32 doi: 10.15302/J-SSCAE-2021.06.010

Abstract:

Developed countries have reduced their carbon emission intensity by adjusting industrial structure, which is an important reference for China to achieve carbon peak and carbon neutralization. In this article, we analyze the changes of total carbon emission, carbon emission per capita, carbon emission intensity, and industrial structure in major developed countries, thus to obtain their experience regarding adjusting industrial structure and reducing carbon emission intensity. Developed countries have generally decoupled economic growth and carbon emissions since 1965 via industrial transfer, scientific and technological innovation, and service industry upgrading; however, a manufacturing hollowing problem emerged. Considering the unfinished industrialization process in China and the large proportion of high energy-consuming industries, we suggest that China cultivates emerging industries and develops digital economy to optimize and upgrade its industrial structure. Additionally, it should further strengthen the manufacturing industry and coordinate industrial transfer in China and abroad while ensuring the security of industrial and supply chains, thereby optimizing the spatial layout of industries and forming a new development pattern.
