X1_2 X2_2 Xn_2 Y_2
X1_3 X2_3 Xn_3 Y_3
X1_4 X2_4 Xn_4 Y_4
X1_m X2_m Xn_m Y_m
Wherein, X1, X2 ..., Xn indicate coke production technique supplemental characteristic and mixed coal data, Y indicates coke quality number According to.
It should be noted that coke quality data Y can be obtained directly by the meter on device (if had on device Corresponding measurement point), it can also be calculated indirectly by the value of other measurement points, the invention is not limited in this regard.
Then, it in order to guarantee the correctness and validity of data, needs to carry out data to the historical data got to locate in advance Reason.Here, data prediction may include at data cleansing processing, data integration processing, data regularization processing and data transformation One of reason is a variety of.Data cleansing processing is corrected inconsistent for the noise in clearing data;Data integration processing is used for Data are merged into a consistent data by multiple data sources to store, such as data warehouse;Data regularization processing is for by such as Aggregation deletes redundancy feature or cluster to reduce the scale of data;Data conversion process is used for data compression to lesser area Between, such as 0.0 to 1.0.In this embodiment, data prediction is data cleansing processing, and its object is to lack to existing part The defects of mistake, repetition, noise, exception, is handled, to obtain the data available of high quality.Data cleansing processing may include lacking One of mistake value filling processing, data format abnormality processing, data value range abnormality processing and data reprocessing are more Kind.
Further, the high quality historical data obtained by data prediction is changed by coke matter by Feature Engineering Measure the training data of prediction model.Here, Feature Engineering refers to the training data that pretreated data are changed into model Process.Feature Engineering may include feature construction, feature extraction and feature selecting, wherein feature construction is from initial data Artificial finds out some features (i.e. data) with physical significance;Feature extraction is that primitive character is converted to one group with bright The feature of aobvious physical significance or statistical significance or core;Feature selecting is that one group of most statistical significance is selected from characteristic set Feature reaches dimensionality reduction.Specifically, the method for feature extraction may include principal component analysis (Principal Component Analysis, PCA), linear discriminant analysis (Linear Discriminant Analysis, LDA) and singular value decomposition One of (Singular Value Decomposition, SVD);The method of feature selecting may include filtering type (Filter) one of selection, packaging type (Wrapper) selection and embedded (Embedding) selection.
In this embodiment, the purpose of Feature Engineering is to delete the abundant or invalid data of part meaning;According to industry Experience screens feature, obtains factor that Coke Quality has a major impact as characteristic index;And use correlation The correlation of algorithm calculating feature and coke quality.
Specifically, the part X1-Xn in table 1 contains all coke production technique supplemental characteristic and mixed coal data, Some data are that height is relevant to high-value product yield in these data, some data are weak related to high-value product yield Or it is incoherent, therefore, it is necessary to be screened by correlation analysis to X1-Xn, retaining Coke Quality data Y has weight Influence data (i.e. effectively).Here, correlation analysis (Correlation analysis) refers to two or more tools The variable element of standby correlation is analyzed, to measure the related intimate degree of two Variable Factors.Correlation analysis It can include but is not limited to chart correlation analysis (line chart and scatter plot), covariance and covariance matrix, related coefficient (Correlation coefficient), regression analysis (Regression analysis) and comentropy and mutual information (Mutual information) etc..
Further, chart correlation analysis is that data are carried out visualization processing, is briefly exactly to draw a diagram.Association side Difference is used to measure the global error of two variables, if the variation tendency of two variables is consistent, covariance is exactly positive value, illustrates two A variable is positively correlated;If the variation tendency of two variables on the contrary, covariance is exactly negative value, illustrates two variable negative correlation;Such as Two variables of fruit are mutually indepedent, then covariance is exactly 0, illustrate that two variables are uncorrelated.Related coefficient is between response variable The statistical indicator of degree in close relations, the value interval of related coefficient is between 1 to -1, wherein 1 indicates two complete lines of variable Property it is related, -1 indicates two variable perfect negative correlations, and 0 indicates that two variables are uncorrelated;There are three types of the calculating of related coefficient, i.e. skin Er Xun (Pearson) related coefficient, Ken Deer (Kendall) related coefficient and Spearman (Spearman) rank correlation coefficient. Regression analysis is the statistical method of two groups or more determining relationship between variables, and regression analysis is divided into one according to the quantity of variable Member returns and multiple regression.Comentropy is used for the unordered degree of metric, and mutual information is actually wider relative entropy Special case.
Further, it is also possible to derive new feature using such as One-Hot coding based on the feature filtered out.Here, One-Hot coding is also known as an efficient coding, is mainly encoded using N bit status register to N number of state, each State all by his independent register-bit, and only have when any one effectively.Table 2 is shown to be obtained by Feature Engineering The example of feature and coke quality data.
