Spectrum finally obtains the apple data of 90 × 256 dimensions as shown in figure 3, seek the spectrum average of 5 entire surfaces of each sample.
The selection of S3, characteristic wave bands
Spectrum picture reacts the difference of apple internal quality, and electronic tongues are obtained by the functional group that apple sample middle reaches separate out
Sense of taste information.Therefore correlation degree between the two is determined using the method for grey relational grade (GRA), chooses sweet tea, acid, salty respectively
3 kinds of corresponding sensitive bands of the basic sense of taste.Before carrying out grey correlation analysis, best sensitive wave is determined using the coefficient of variation
Segment number.Comprehensive coefficient shows that more greatly the correlation between variable is lower, research with 2 for interval characteristic wave bands number to become
The influence of different coefficient, shown as seen from Figure 4, characteristic wave bands number achieves the highest coefficient of variation at 10.It is wherein grey
In color degree of association method, first, multiple dimension data are converted to unified Dimensionless Form, it is sense of taste information to define reference sequence
Ordered series of numbers compares ordered series of numbers and carries out dimensionless processing for spectral information ordered series of numbers under each wave bands of 380-1038nm, the sense of taste is eliminated with this
With the difference of spectral information dimension.Then, the ash of each single sense of taste information ordered series of numbers and the spectral information ordered series of numbers under all band is sought
Color incidence coefficient.Finally, the grey relational grade of each wave band is sought.The results are shown in Table 1,10 associations before each single sense of taste information
The higher characteristic wave bands of angle value.
10 characteristic wave bands before 1 each sense of taste of table
The structure of S4, apple sense of taste Visualization Model
Spectrum has discreteness with sense of taste information data, and local linear and non-linear relation are presented therebetween, and SVM
Main thought is to establish a regression hyperplane as decision surface, and multidimensional data is mapped to higher dimensional space using kernel function, is made
It is as linear as possible, to solve the local nonlinearity of initial data, finally make all data in set to hyperplane distance most
Closely.Use SVM to predict the concentration value of each sense of taste information discrete point herein based on this, wherein hyperplane function, RBF kernel functions and
Regression function formula (2), (3), (4) are as follows respectively.SVR modeling process results depend on parameter c and g, correct effective parameter
Selection has good recurrence performance to support vector machines.Therefore, it is based on genetic algorithm (GA) and grid type search (GS) herein
Method to carry out optimizing to parameter c and g, as shown in Figure 5.In genetic algorithm, maximum genetic algebra be 100, initial kind
Group's number is 20, and it is 0 to 100 that the search range of parameter c, which is 0 to 100, g,.In grid type searching method, carried out for interval with 0.5
The search range of parameter optimization, parameter c and g is 2-10To 210.During establishing model, because experiment is detected as whole sample
The sense of taste value of product, therefore when carrying out spectroscopic data and sense of taste information MAP, the spectral value under each wave band is subjected to mean value and is sought
Carry out the foundation of model again afterwards.2/3 spectroscopic data sample is wherein selected as training set using Kennard-Stone methods, 1/3
A spectroscopic data is selected as forecast set, and spectrum-sense of taste information visuallization analysis is realized based on GS-SVM and GA-SVM.As a result such as table
The parameter optimization process of 2 display GA-SVM, genetic algorithm is quickly under the conditions of it is 0.01667 to reach best fitness Mse
Filtered out modeling optimized parameter c be 6.3859, g 83.0159, the parameter optimization process of GS-SVM, grid type search up to
It is that 22.6274, g is to have filtered out modeling optimized parameter c under the conditions of being 0.0037346 to best fitness Mse
0.0019531, therefore the model for selecting GS-SVM to be sought as apple sense of taste value.
K (x, x ')=exp (g Px-x ' P2) (2)
F (x)=w φ (x)+b (3)
The normal vector of w- hyperplane in formula, φ (x)-nonlinear mapping functions, b- amount of bias, g- spread factors
The end value of table 2 c and g searching processes
S5, sense of taste visualization are presented
After GS-SVM model foundations, the pre- measured spectral values under 10 wave bands are inputted by point, find out each point spectral value
Under the sense of taste prediction output valve be denoted as K (i, j), convert sense of taste value to corresponding actual color value, can by apple sense of taste information
It is presented depending on changing, Fig. 6 is sweet taste, tart flavour, saline taste single-point sense of taste distribution map, and legend gradually thickens from navy blue to brick-red taste.
As seen from the figure, for Acker threose heart apple mainly based on sweet taste, tart flavour, saline taste is very light, and sweet taste is most dense and distribution is most wide.
Sweet taste is mainly distributed on equatorial line both sides, and central axes part is compared with sweet tea；The distributing position of tart flavour is similar to sweet taste；Saline taste be then
Equator section more uniformly and is distributed more extensive.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the principle of the present invention, it can also make several improvements and retouch, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
