specific Embodiment approach 1

[0017] Specific implementation manner 1: The specific steps of an energy efficiency evaluation method based on a multi-model fusion strategy are:

[0018] Step 1: Normalize the data to obtain a normalized training set;

[0019] Step 2: Perform feature selection on the normalized training set obtained in Step 1;

[0020] Step 3: Establish a multi-classifier fusion evaluation model according to Step 1 and Step 2, and obtain the classification result of energy efficiency evaluation;

[0021] Step 4: Perform cluster analysis on the classification results obtained in Step 3 to obtain the final clustering results.

specific Embodiment approach 2

[0022] Specific embodiment two: this embodiment is different from specific embodiment one in that: the data in step one specifically includes: primary energy production, total energy consumption, energy consumption elasticity coefficient, GDP, energy industry investment amount, unit GDP energy consumption, capital stock, and sulfur dioxide emission coefficient.

[0023] Other steps and parameters are the same as in the first embodiment.

specific Embodiment approach 3

[0024] Specific embodiment three: This embodiment is different from specific embodiment one or two in that: in the step one, the data is normalized, and the specific process of obtaining the normalized training set is:

[0025] Collect panel data from many provinces, municipalities and autonomous regions across the country, and carry out standardized preprocessing of the data. The standardization of the data is to scale the data proportionally, remove the unit limit of the data, and convert it into a dimensionless pure value, which is convenient for comparison and weighting. 0-1 standardization (also called normalization) is the most typical method of data standardization, which makes the result fall into the interval [0,1] through linear transformation of the original data. Considering that the characteristic values ​​in the data set used in the present invention are all positive values, a simplified conversion function is used to normalize each component. If there are N sample...

Abstract

The invention relates to an energy efficiency evaluation method based on a multi-model fusion strategy. The problems that existing energy efficiency computing features are difficult to select, and the model evaluation result is inaccurate are solved. The method comprises the steps that 1, data is subjected to normalization processing, and a normalization training set is obtained; 2, the normalization training set obtained in the step 1 is subjected to feature selection, features are selected by adopting a fusion method of combining information gain with kernel principal component analysis, that is to say, after feature ordering is obtained through information gain calculation, verifying calculation is conducted through a principal component analysis method; 3, a multi-classifier fused evaluation module is built according to the step 1 and the step 2, a classification result obtained in the step 3 is subjected to cluster analysis, and the final cluster result is obtained. The energy efficiency evaluation method is applied to the field of energy efficiency effective evaluation.

Description

Technical field [0001] The invention relates to an energy efficiency evaluation method based on a multi-model fusion strategy. Background technique [0002] With the increasingly prominent energy and environmental issues, energy efficiency evaluation methods have also received increasing attention. Many scholars in the world have studied the improvement of energy efficiency and energy saving potential from different angles. Take China as an example. In recent years, the economy has maintained rapid and strong development, but the economic growth method is still very extensive. The current situation of high resource and energy consumption, low utilization rate and serious environmental pollution is still an indisputable fact. Energy efficiency is international Shanghai is still in a backward stage. At present, China's unreasonable energy consumption structure dominated by coal has seriously affected the energy utilization efficiency of the entire energy system, posing a challeng...
