Specific embodiment
In order to make those skilled in the art more fully understand the technical solution in this specification one or more embodiment,
Below in conjunction with the attached drawing in this specification one or more embodiment, to the technology in this specification one or more embodiment
Scheme is clearly and completely described, it is clear that described embodiment is only a part of the embodiment, rather than whole realities
Apply example.Based on this specification one or more embodiment, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present application.
In practical business, be likely encountered such scene: data side A possesses own data, it is desirable to if evaluation and test
By the data of data side B, the modelling effect of itself can be promoted.For example, it is assumed that data side A utilizes owned number
It according to a machine learning model M is had trained, still, is found in model measurement, the prediction effect of the model is not satisfactory, and pre-
Phase predicted value has a certain distance.If participating in the training and optimization of model M using the data of data side B, mould can be made
The effect of type M is promoted, then can choose the data of purchase data side B to assist modeling.
In above-mentioned scene, it is involved in a problem i.e.: how to determine whether data side B is effective, if data side B
Data it is helpful to the modeling of model M, facilitate the effect of lift scheme M, then confirm that the data of data side B are effective.
And the data validity of which kind of mode verify data side B is used, it will be at least one embodiment of this specification content to be described,
Also, in the verification method of data validity, will realize: data side A does not obtain the data of data side B, and data side A is not let out
That reveals itself possesses data.
As follows by taking data side A and data side B as an example, the verification method of data validity is described, and this method will verify number
It is whether effective according to the data of square B.
For example, data side A can be known as to the first data side, data side B is known as the second data side.
Firstly, shown in Figure 1, the data that the first data side possesses are properly termed as the first data.In first data
It may include: the training set and test set of machine learning model.
Wherein, training set is used for the training of machine learning model, for example, the training sample D in the training setA(XA, YA)
In, XAIt is variable, YAIt is label.The label YAIndicate above-mentioned variable XABy the expection predicted value of the machine learning model,
It is equivalent to a kind of model for having supervision.
Test set is used for the prediction of machine learning model, for example, the test sample D in test setB(XB, YB) equally include
Variable and label.
For example, the variable of above-mentioned training sample and test sample, it can include " entering moding amount " and " do not enter moding
Amount ".Wherein, the training for entering moding amount and taking part in model in training sample, and the moding amount that enters in test sample takes part in mould
Type prediction, and do not enter training and prediction that moding amount is not engaged in model.
Be exemplified below: for judging that some user is high-quality user or user inferior, which can use multiple changes
Amount indicates, for example, age, address, length of service, annual income etc..Assuming that a user can be indicated with 8 variables, U f1,
F2, f3, f4 ... .f8 } it be a user U include this eight variables of f1 to f8.It, can be first using wherein in training pattern
Five variable f1 to f5, and f6 to f8 is temporarily first not involved in the training of model.
So, in training sample DA(XA, YA) in, it may include multiple user's samples, for example, user U1, user U2, use
Family U3 etc..Each user's sample is DA(XA, YA), including variable and label, variable X thereinAIt may include above-mentioned use
Five variable f1 to f5 at family, the variable in each user's sample are this five variables, and variate-value can be different;And it is described
Label YACan be the user is high-quality user or user inferior, for example, high-quality user is indicated with 11,00 table of user inferior
Show.
The test sample D of prediction for machine learning modelB(XB, YB) it equally include variable and label, carrying out model
When prediction, DBThe variable used includes five variable f1 to f5 of user, and f6 to f8 has neither part nor lot in prediction, and label is that the user is excellent
Matter user or user inferior.Test set is the moding amount that enters of test sample to be inputted trained model, and sentence in prediction
Whether the output result of disconnected model is consistent with label.
By 1 example training sample of table, test sample and therein it can enter moding amount and do not enter moding amount as follows.
As shown in table 1, these samples of U1, U2 and U3 will participate in the training of model, be properly termed as training set.But participating in model instruction
When practicing, f1 only therein to f5 variable is participated in, and is properly termed as into moding amount, and f6 is temporarily not engaged in model to f8 variable and instructs
Practice, does not enter moding amount referred to as.YAIt is label.For another example, these samples of the U7 in test set and U8 are the predictions for model, will
The moding amount that enters in these test samples inputs trained model, and obtains the output result of model.Likewise, U7 and U8 exist
When input model, and only f1 is participated in f5 variable, and f6 to f8 variable has neither part nor lot in.If the following table 1 is only example, in actual implementation
It is not limited thereto, the variable for including in each sample can change.
1 first data D of tableA(XA, YA)
In the above example, when testing using the test sample in table 1 model, the effect of model is found less
Ideal, at this time, it is assumed that have at least two second data sides such as data side B that can provide data, this multiple data side B can possess
Different variables, or possess the different variate-values of identical variable.Can by selected section data side B in multiple data side B Lai
Assist Optimized model.For example, can be by one optimal data side B of selection in three data side B, or also can choose two
Or multiple data side B, decision can be considered according to actual business requirement.And it is more excellent which how to be assessed in these three data sides B,
The data selecting method of at least one embodiment of this specification then can be used.
Fig. 2 describes the data selecting method of at least one embodiment of this specification offer, and this method may include as follows
It handles, do not limit each step in specific implementation executes sequence:
In step 200, according to training sample, training machine learning model.
This step, which can be used in training sample, enters moding amount and label training pattern.For example, can be in table 1
The data training pattern of U1, U2 and U3, U1, U2 and U3 therein are user's samples, and each user's sample may include eight changes
Amount, and in training, five variables of f1 therein to f5 can be used.
In step 202, the moding amount input machine learning model that enters in test sample is obtained into predicted value.
For example, the test sample U7 and U8 in table 1 are not engaged in the training of model, but it can be used for the test of model.
It in the model that training is completed in input step 200, can be obtained using five variables of f1 to f5 in test sample as inputting
Model exports result, that is, predicted value.The moding amount that enters of tag representation test sample in the test sample inputs machine learning mould
The expection predicted value of type.
In step 204, according to the label in predicted value and test sample, the corresponding residual error of the test sample is obtained.
For example, the corresponding label of U7 and U8 is the Y in table 1A7And YA8, and residual error can be the difference between predicted value and label, the residual error
It can be used to indicate that the difference between the reality output result of model and desired output result, so as to for measuring model
Prediction effect.
In step 206, the residual error is sent respectively at least two second data sides to be selected by data side A.This
The corresponding residual error of the test sample of data side A can be sent to data side B by step, also that training sample and test sample is corresponding
Sample identification be sent to data side B.For example, the sample identification may include the User ID of U1 to U3.
For example, User ID can be encrypted by Encryption Algorithm such as MD5, to avoid user information leakage.What is transmitted is residual
Difference is that the gap between original tag is measured, and can also play the purpose of protection privacy of user.
Wherein, it should be noted that in following step, in step 206 to step 214, with data side A to two data
It is described for square B, can there is greater number of data side B in actual implementation.In the signal of Fig. 2, to two data side B
Sample matches and the regression fit processing that transmission sample identification and residual error and the two data sides B are respectively carried out, have used phase
Same step serial number, for example, being all step 206, however, it will be understood that this is that two data side B are respectively executed
Operation.
In a step 208, data side B carries out sample matches according to the sample identification, obtains the second data.
For example, data side B can carry out sample matches according to the User ID of U1 and U3, obtains and intend for participating in subsequent return
The second data closed.For example, may refer to above-mentioned table 2, the data of U1 and U3 that data side B possesses are obtained, and obtain variable
F9 to f11.
May include in second data corresponding data side A training sample and test sample sample ID data.It can
User's sample of the sample identification of the training sample of corresponding data side A is also referred to as the training sample in data side B, will correspond to
User's sample of the sample identification of the test sample of data side A is known as the test sample in data side B.
In step 210, data side B is fitted the residual error based on the variable regression in second data, is returned
Evaluation index.
For example, multiple user's samples in test sample, each sample can correspond to a residual error, and multiple samples can
To obtain multiple residual errors.Each variable regression in the training sample of data side B can be used and be fitted above-mentioned multiple residual errors.It is quasi-
The purpose of conjunction is to fit a polynomial function according to training sample, this function can be good at being fitted above-mentioned
Multiple residual errors.
For example, it is assumed that above-mentioned multiple residual errors may include y1、y2……yn.Wherein, n is natural number.
Variable in each training sample may include: x1、x2……xi.Wherein, i is natural number.
y1=a1*x11+a2*x12+…….ai*x1i;……(1)
y2=a1*x21+a2*x22+…….ai*x2i;……(2)
……………
yn=a1*xn1+a2*xn2+…….ai*xni;……(n)
Wherein, each residual error y1To ynBe it is known, the value of the variable in each training sample is also known, for example,
{ x in above-mentioned formula (1)11、x12……x1nBe each variable in a training sample value, { the x in formula (2)21、
x22……x2nBe each variable in another training sample value.It, can be with by above-mentioned formula (1) to formula (n)
Obtain coefficient a1、a2……aiValue, finally obtain regression equation y=a1*x1+a2*x2+…….ai*xi。
The corresponding variable importance weight of the available each variable of the regression equation acquired, above-mentioned a1、a2……
aiValue be the corresponding variable importance weight of each variable.
It should be noted that above-mentioned citing is by taking linear regression as an example, however, it is not limited to this.Other can also be used
Recurrence mode, e.g., polynomial regression.
Also, the recurrence evaluation index of this recurrence can also be calculated.Return evaluation index can there are many, for example, can
To be mean square error, root-mean-square error (Root Mean Squard Error, RMSE), mean absolute error etc..Return evaluation
Index can be used for measuring the effect of regression fit.
For example, returning evaluation index by taking mean square error as an example:
In formula (5), m indicates the quantity of test sample, yiIndicate true value, ynIndicate predicted value, true value and prediction
Value makes the difference, then square after sum-average arithmetic.For example, for each test sample, the corresponding residual error of each test sample, with
For one of test sample, the corresponding residual error of the test sample is exactly true value, and uses the variable in the test sample
Value substitute into regression equation obtained above, obtained residual values are exactly predicted value.According to above-mentioned formula (5), to each survey
The true value and predicted value of sample sheet make the difference, and square after sum-average arithmetic, it can obtain return evaluation index mean square error.
In the step 212, the second data side returns to the first data side for evaluation index is returned.It is described in this step
The recurrence evaluation index that oneself is calculated can be returned to data side A respectively by least two data side B.
In addition, data side B can also obtain at least one of following parameter: sample matches rate and the variable missing of the second data
Rate.Wherein, the sample matches rate, which can be understood as data side B, can find the data that the data side A of much ratios is required,
For example, the sample identification that data side A is transmitted to data side B there are eight, that is, data side B is required to provide user's sample of eight users.
And data side B only has 6, then sample matching rate can be 6/8*100%=75%.The variable miss rate is understood that
Are as follows: data side B can find some variable of data side A requirement, only some missings of variate-value.For example, the data side side B has 10
The data of a user's sample, all there are also variable f10 for this 10 user's samples, but wherein there are two variable of the user at f10
Value is sky, that is, variable missing occurs, variable miss rate can be 20%.
Data side B can will return evaluation index and return to data side A, can also lack the sample matches rate and variable
At least one of mistake rate returns to data side A, so that the first data side is in conjunction with recurrence evaluation index, the sample matches rate
The selection of data side is carried out with variable miss rate.
In step 214, the first data side is selected by comparing the recurrence evaluation index of multiple second data sides to determine
The second data side of part.
In this step, data side A can be individually according to the comparison for returning evaluation index, for example, can be by two data side B
The recurrence evaluation index of return compares, which index is more excellent just to select by which data side B.It can certainly select to return and evaluate
The preferably multiple data side B of index.
Alternatively, sample matches rate, variable miss rate can also be comprehensively considered and return evaluation index, for example, can first select
The second data side that sample matches rate is higher than preset threshold is selected out, matching rate is lower to be given up.It is high by sample matches rate again
The selective goal preferably data side B in the second data of preset threshold is ranked up for example, evaluation index can will be returned,
Data side B of the selected and sorted at former.Certainly, in other examples, can also comprehensively consider again variable miss rate etc. its
His index.For example, can be sample matches rate and sample miss rate given threshold, no matter the second data recurrence lower than threshold value is commented
How is valence index, not reselection.
A variety of regression algorithms can be used in above-mentioned recurrence, but are the need to ensure that each data side B uses unification
Regression algorithm and unified recurrence evaluation index, avoid due to each data side B select Different Effects subsequent contrast it is just.
In addition, the judgement of the data validity of this step, can be computer automatic execution, it is also possible to manually perform,
For example, data side B by sample matches rate, sample miss rate and is being returned after evaluation index returns to data side A, by data side A
Administrative staff judged according to these indexs returned, to carry out the selection of data side B.
The residual error of modeling is only sent to by the data selecting method of this specification one or more embodiment, data side A
Multiple data side B, multiple data side B also will only return evaluation index and return to data side A, and the interaction of data side is that modeling is residual
Difference and recurrence evaluation index, and the private data of non-user, therefore any of user can not be revealed in both sides' interactive process
Private data.Also, it can also be according to the recurrence evaluation index that multiple data side B are returned by selected section in multiple data side B
Data protect internal data privacy while realizing the selected section data in by multiple external datas.
