Specific embodiment
In order to which the purpose of the present invention, technical solution and beneficial effect is more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only used to explain this hair It is bright, it is not intended to limit the present invention.
In order to facilitate understanding, noun involved in the embodiment of the present invention is explained below.
Isolated forest model: (Isolation Forest, abbreviation iForest) is a kind of suitable for continuous data The unsupervised anomaly detection method of (Continuous numerical data), that is, do not need markd sample to train, but Feature needs to be continuous.For how to search which point be easy isolated (isolated), iForest used it is a set of very Efficient strategy.In isolated forest, recursively random division data set, until all sample points are all isolated.At this Under the strategy of kind random division, abnormal point usually has shorter path.
Global abnormal: abnormal relative to other whole samples.For example, as shown in Figure 1, the value of global abnormal point is greater than song The value of all the points on line.
Local anomaly: abnormal only with respect to other samples in same position in the period.For example, as shown in Figure 1, part The value of abnormal point is not greater than the value of all the points on curve, but is greater than period inner curve in the value at the moment.
During concrete practice, it was found by the inventors of the present invention that the production and operation data of internet industry have one mostly Fixed cycle, often difference is very big for the different moments waving interval in the period, relies on artificial experience and threshold value is arranged, based on to be measured The fluctuation range of curve is analyzed, and alarm threshold is arranged, and this method configuration process is cumbersome, often there is more accidentally alarm.
For this purpose, the present inventor using unsupervised algorithm to abnormal it is considered that can be detected, unsupervised algorithm Without realizing that marker samples are classified, and the case where be applicable in positive and negative imbalanced training sets.Based on algorithm accuracy rate, computation complexity, lead to With the performance of property etc., iForest is better than other unsupervised algorithms, be adapted to more scenes, multi-service, high frequency abnormality detection field Scape.But tradition iForest is when detecting abnormal data, does not take into account that the timing of data, therefore can only detection data it is complete Office is abnormal, and is unable to the local anomaly of detection data.And the daily operation data of internet is generally periodically variable data, Many local anomalies are also the part for needing to pay special attention to.For this purpose, in the embodiment of the present invention, in the isolated forest model of training, The temporal aspect of target object is added in the feature of training sample.In the data to be tested of detected target object, it is based on mesh The data to be tested of object are marked, every random binary tree in isolated forest model is traversed, determines target object at every random two Position on fork tree.Then the position according to target object on every random binary tree, determines the abnormal score of target object, Later further according to the abnormal score of target object, the abnormal conditions of target object are determined.Due in the isolated forest model of training, The temporal aspect of target object is added in the feature of training sample, therefore uses trained isolated forest model detected target object Abnormal conditions when, using the temporal aspect of target object as judge target object whether Yi Chang factor, thus can detect Global abnormal can also detect local anomaly, to increase the applicable application scenarios of isolated forest, reduce the mistake of abnormality detection Alarm rate.
Abnormal deviation data examination method in the embodiment of the present invention can be applied to application scenarios as shown in Figure 2, answer at this With in scene include abnormality detection server 201, terminal device 202.
Abnormality detection server 201 can be the server cluster or cloud meter of a server or several servers composition Calculation center.Terminal device 202 is the electronic equipment for having network communications capability, which can be smart phone, plate Computer or portable personal computer etc..
Abnormality detection server 201 establishes isolated forest model for each target object, is getting target object After data to be tested, using the abnormal conditions of the corresponding isolated forest model detected target object of target object.Abnormality detection clothes The abnormal conditions of target object are sent to terminal device 202 by wireless network by business device 201.Terminal device 202 is with chart etc. The abnormal conditions of target object are showed operation maintenance personnel by form.
Based on application scenario diagram shown in Fig. 2, the embodiment of the invention provides a kind of process of abnormal deviation data examination method, The process of this method can be executed by anomaly data detection device, and anomaly data detection device can be abnormality detection shown in Fig. 2 Server 201, as shown in Figure 3, comprising the following steps:
Step S301 obtains the data to be tested of target object.
Specifically, data to be tested can be the operation data of all kinds of operation scenes, and target object can be operation data Index.For example, by the amount of supplementing with money of game money, consumption and can be given when the game money to gaming platform is monitored The amount of sending is used as target object.For another example, when the trading volume to transaction platform is monitored, trading volume, transaction can be blocked Cut amount, transaction interception ratio is all used as target object.
Step S302, the data to be tested based on target object traverse every random binary tree in isolated forest model, really Set the goal position of the object on every random binary tree.
Specifically, isolated forest model includes more random binary trees, and isolated forest model is the history with target object Data are that training sample training obtains, for example isolates forest mould by training sample training of 30 days data before current time Type.The historical data cyclically-varying of target object, the feature of training sample include at least the temporal aspect of target object.Timing Feature is for current period compared to preceding several periods in variation mutually in the same time.
In a kind of possible embodiment, temporal aspect can for current period target object data and preceding several weeks Phase the average value of data mutually in the same time ratio, i.e., when the data of target object are identical compared in preceding several periods this moment The average level of the data at quarter increases or reduces how many.Illustratively, the data of target object are set as X (t), define target The temporal aspect Y (t) of object meets following formula (1):
Wherein, X (t) is the data of target object, and Y (t) is the temporal aspect of target object, and T is the period of target object, M is the amount of cycles before X (t).
In a kind of possible embodiment, temporal aspect can for current period target object data and preceding several weeks Difference of the phase in the average value of data mutually in the same time.Illustratively, the data of target object are set as X (t), define target pair The temporal aspect Y (t) of elephant meets following formula (2):
Wherein, X (t) is the data of target object, and Y (t) is the temporal aspect of target object, and T is the period of target object, M is the amount of cycles before X (t).
Step S303 determines the abnormal score of target object according to position of the target object on every random binary tree.
Specifically, the abnormal score of target object is determined using following formula (3):
Wherein,For the abnormal score of target object, CFor each random y-bend in isolated forest model The average path length of tree, h (x) are path length of the target object x in isolated forest on every random binary tree, and E is to ask Average value.
Further, path length h (x) of the target object x in isolated forest on every random binary tree meets following Formula (4):
Wherein, n is the sample number where target object x on leaf node, and e is target object x from root node to leaf section The number of edges that point passes through, H (n-1) ≈ ln (n-1)+ξ, Euler's constant ξ=0.5772156649.
Step S304 determines the abnormal conditions of target object according to the abnormal score of target object.
Specifically, outlier threshold can be set in advance, for example set 0.7 for outlier threshold, when the exception of target object When score value is greater than 0.7, target object is determined as exception, is otherwise determined as target object normally.
Due to adding the temporal aspect of target object in the feature of training sample, therefore adopting in the isolated forest model of training When with the abnormal conditions of trained isolated forest model detected target object, using the temporal aspect of target object as judging mesh Mark object whether Yi Chang factor, thus can detect global abnormal, can also detect local anomaly, to increase isolated forest Applicable application scenarios reduce the false alarm rate of abnormality detection.
Optionally, in above-mentioned steps S302, the training process of isolated forest model specifically includes following steps, such as Fig. 4 It is shown:
Step S401 obtains the historical data of target object as training sample.
Such as obtain current time before 30 days target object data as training sample.
Step S402 determines the characteristic set of training sample, the temporal aspect of target object is included at least in characteristic set.
It specifically, include the feature of each dimension of target object, such as target object sheet in the characteristic set of training sample Body can be used as feature of a dimension, such as temporal aspect etc..
Step S403 carries out n times random sampling to training sample, extracts M sample every time and construct random binary tree.
When constructing every random binary tree, using the feature randomly selected from characteristic set as boundary feature, with boundary The value randomly selected in the value interval of feature is greater than 0, N and is greater than 0 as cut off value, M.The stopping when meeting preset condition, it is raw At random binary tree, wherein preset condition can be that sample can not divide again or random binary tree reaches depth capacity.
Step S404 determines isolated forest model according to N of building random binary tree.
It is illustrated so that target object is the game money amount of supplementing with money as an example below, as shown in figure 5, before obtaining current time The daily each period game money amount of supplementing with money X (t) is used as training sample, period T within 30 days.Extract the game money amount of supplementing with money X (t) when Sequence characteristics Y (t), wherein temporal aspect Y (t) be current period the amount of supplementing with money with preceding several periods in the amount of supplementing with money mutually in the same time Average value ratio.Feature in defined feature set includes the game money amount of supplementing with money X (t) and temporal aspect Y (t).
Randomly selected from training sample 4 training samples { a, b, c, d } for construct first random binary tree, from spy Collection randomly selects a feature as boundary feature in closing.It is special as boundary that the game money amount of supplementing with money X (t) has been randomly selected in setting Sign, then randomly select a value as cut off value out of the game money amount of supplementing with money X (t) value interval.If above-mentioned training sample The game money amount of supplementing with money X (t) is less than cut off value, then is divided into left child node, is otherwise divided into right child node.Setting training sample a, B, the game money amount of supplementing with money the X (t) of c is less than cut off value, then training sample a, b, c is divided into left child node, the trip of training sample d The coin amount of supplementing with money X (t) is played not less than cut off value, then training sample d is divided into right child node.Whether the current random binary tree of judgement Meet any one following preset condition:
Whether preset condition one, current random binary tree reach depth capacity.
Preset condition two, currently whether the training sample of each node of random binary tree can not be further continued for dividing.
It can continue to divide including 3 training samples in left child node in current random binary tree.In right child node only 1 training sample, it is not possible to be further continued for dividing.For left child node, a feature is randomly selected from characteristic set and is used as and is divided Boundary's feature.Setting has randomly selected temporal aspect Y (t) as boundary feature, then out of temporal aspect Y (t) value interval with Machine chooses a value and is used as cut off value.When the temporal aspect Y (t) of training sample is less than cut off value, it is divided into left Sun Jiedian, otherwise It is divided into right Sun Jiedian.It sets in training sample a, b, c, the temporal aspect Y (t) of training sample a is less than cut off value, then trains sample This is divided into left Sun Jiedian, and the temporal aspect Y (t) of training sample b, c are not less than cut off value, then training sample b, c is divided into Right Sun Jiedian.Then judge whether current random binary tree meets preset condition again, if satisfied, then terminate to train and generate with Machine binary tree, otherwise continues to divide training sample according to above-mentioned steps.After generating a random binary tree, then from instruction Practice and randomly select 4 training samples in sample and construct another random binary tree, for example, randomly select training sample a, b, d, E }, { a, b, e, f } etc..And so on, when the quantity of the random binary tree of building is equal to preset value, using the random of building Binary tree forms isolated forest.
Due to when constructing every random binary tree of isolated forest, using the temporal aspect of target object as characteristic set In a feature, therefore randomly selected from characteristic set feature as boundary feature when, the temporal aspect of target object can It can be extracted and divide training sample as boundary feature, so that the random binary tree of building and the temporal aspect of target object be made to have Standby correlation.
Optionally, when the historical data of target object updates, using the historical data of update as training sample re -training, Obtain the isolated forest model updated.
Illustratively, as shown in fig. 6, setting target object the game money amount of supplementing with money X (t), gaming platform in order to promote, The activity for sending game money is supplemented in daily 20 points of releases with money.During activity, daily 20 points, the game money amount of supplementing with money X (t) occurs supplementing height with money Peak, 3 points of a, b, c as shown in FIG. 6.When not accounting for popularization activity, 3 points of a, b, c can may be remembered as global different Chang Dian, and actually 3 points of a, b, c are peak caused by normal popularization activity.For this purpose, can be supplemented with money detecting daily game money When whether amount X (t) is abnormal, obtained using daily 30 days in the past historical datas as training sample re -training and isolate forest mould Type.When daily 20 points of numbers for peak occur are more and more, the isolated forest model that re -training obtains will capture this rule, To increasingly tend to daily 20 points of peak being considered as normal point.By constantly updating isolated forest model, so that in industry When business is promoted and data occurs and periodically uprush, can gradually identify this it is normal periodically increase sharply, reduce abnormal score, reduce and miss Alarm.
Optionally, multiple target objects are frequently included in a business scenario, when a target object occurs abnormal simultaneously It cannot illustrate that exception has occurred in entire business scenario, if directly alerting at this time, false alarm rate will be increased, for this purpose, the present invention is implemented Exception Type is determined according to the abnormal conditions of multiple target objects in example, then determines whether to alert according to Exception Type.
Specifically, Exception Type includes but is not limited to that business draws receipts, game money to be brushed, strategy fails, and wherein business, which is drawn, receives Belong to the type for not needing alarm, and game money is brushed, strategy unsuccessfully needs to alert.
When determining Exception Type according to the abnormal conditions of multiple target objects, the embodiment of the present invention at least provides two Kind embodiment:
In a kind of possible embodiment, the abnormal conditions of multiple target objects are inputted into preset decision matrix, really Determine Exception Type.
Specifically, decision matrix can be constructed according to expertise in advance, decision matrix illustrates each target object Correlation between abnormal conditions and Exception Type.
In a kind of possible embodiment, the abnormal conditions of multiple target objects are inputted into disaggregated model, are determined abnormal Type, disaggregated model are obtained by the mapping relations of the abnormal conditions and Exception Type that learn multiple target objects.
Specifically, disaggregated model can with two disaggregated models, be also possible to more disaggregated models, in specific implementation, disaggregated model Including but not limited to decision tree, neural network model.When constructing disaggregated model, for example when constructing decision tree, acquisition includes The data of the business scenario of multiple target objects are as training sample, then manually according to target object each in training sample Abnormal conditions mark the Exception Type of training sample, later again using the training sample building decision tree that Exception Type is marked. After the abnormal conditions for determining multiple target objects using isolated forest, the abnormal conditions of multiple target objects are inputted into decision tree mould Type, output abnormality type.
Exception Type is judged by the abnormal conditions of the multiple target objects of combination, then determines whether to alert again, compared to According to single target object abnormal conditions and for alerting, accuracy is higher, can greatly reduce due to producing spy in practice It is accidentally alerted caused by different situation, lifting system overall accuracy.
