Definitions
- Implementations described herein relate generally to information processing. More particularly, implementations described herein relate to a machine learning scheme.
- Data mining is a process of sorting through large amounts of data and eliciting relevant information.
- a machine learning system may be employed to perform data mining operations.
- minimizing cost associated with providing a product or a service is beneficial. For example, providers may have up to ten times the expenditures associated with attracting and/or obtaining a new customer than they may have in retaining an existing customer.
- an abundance of information may be created based on a customer's activity. An operator may try to gain knowledge from this information (e.g., customer behavior) using statistics, creating reports, etc.
- customer churn i.e., customers that potentially may terminate their service
- an expert needs to configure a knowledge extraction system to extract a particular type of knowledge from the communications network. This configuration process may need to be performed for each type of knowledge that the operator wishes to extract.
- the configuration of the knowledge extraction system requires the expert to design and input appropriate tasks (e.g., machine learning algorithms, data sets, schemas for data repositories, mathematical transformations, etc.) so that the appropriate knowledge can be discovered and utilized.
- this approach tends to be time-consuming to the extent that the operator may lose customers before customer churn is detected and possibly prevented.
- a method to prevent churn of customers may include creating a customer model based on churned customers' behavior; creating one or more other customer models corresponding to existing customers' behavior during corresponding one or more time periods; comparing the customer model to the one or more other customer models; identifying whether the existing customers are potential churn customers based on the comparison; and generating measures to retain the existing customers when the existing customers are identified as potential churn customers.
- a device may include one or more components to collect data that includes customer activity associated with a service provided by a network; create a customer model that includes metrics corresponding to churned customers based on the collected data; create another customer model that includes metrics corresponding to existing customers based on the collected data; compare the customer model to the other customer model; and identify whether the existing customers are potential churn customers based on the comparison.
- one or more computer-readable mediums may contain instructions that include one or more instructions for collecting data that includes customer activity associated with a service utilized by customers; one or more instructions for creating a customer model, based on the collected data, that corresponds to a segment of the customers classified as already churned customers; one or more instructions for creating another customer model, based on the collected data, that corresponds to a segment of the customers classified as existing customers; one or more instructions for comparing the customer model with the other customer model; one or more instructions of determining whether the existing customers are classifiable as potential churn customers based on the comparison; and one or more instructions for generating a new offer of service to minimize the churning of the potential churn customers when it is determined that the existing customers are classifiable as potential churn customers.

- the machine learning system may identify potential churn customers based on the training data and the collected data.
- the training data and the collected data may be utilized to form various customer models.

- the machine learning system may further provide measurements relating to how the behavior of potential churn customers is evolving toward the behavior of already churned customers.
- the machine learning system may also determine the reason for customer behavior and create appropriate counter measures to address customer behavior.
- the machine learning system will be described in connection with minimizing churn of existing customers.
- one or more components of the machine learning system may be described as, for example, including a certain type of information, performing a specific function, etc., tailored toward minimizing churn of existing customers.
- one or more components of the machine learning system may perform a different function, utilize different information, etc. For example, if the machine learning system were to be described in connection with maximizing profits, one or more components may perform different functions, utilize different data, models, etc., than if the machine learning system were to be described in connection with minimizing churn of existing customers.

- Fig. 3 is a flow diagram illustrating an exemplary process 300 for minimizing churn of potential churn customers.
- Process 300 may begin with retrieving data of already churned customers (block 305).
- data manager 105 may have previously collected data associated with already churned customers and stored this data in data storage 1 10.
- the data may correspond to indications exhibited by a customer(s) that already churned.
- These indications may include, for example, complaining call(s) to customer support, reduced usage of service, cancelling a portion of service, changing from a higher-end service to a lower-end service (e.g., an unlimited usage of a service plan to a limited usage of a service plan), reduced payment transactions, and/or other types of customer behavior that may be indicative of customer dissatisfaction.
- Data manager 105 may have previously collected this data during a period of time prior to the churning of a customer(s). In one implementation, data manager 105 may automatically collect data on a customer or a group of customers when one or multiple indications of dissatisfaction occur. Data manager 105 may retrieve this collected data and provide it to customer model creator 120.
- a customer model may be created (block 310).
- Customer model creator 120 may utilize the collected stored in data storage 1 10 to create an already churned customer model (i.e., a machine learning model of already churned customer(s) (MLMc)).
- MLMc machine learning model of already churned customer(s)
- customer model creator 120 may utilize collected data 405 associated with already churned customers to create MLMc.
- customer model creator 120 may process collected data 405 to form customer table 410.
- Customer table 410 may include a customer field 415 and a customer vector field 420.
- Customer field 415 may correspond to an identifier of an already churned customer (e.g., a name, a character string).
- Customer vector field 420 may correspond to a mathematical transformation of collected data 405, associated with an already churned customer, in the form of a vector.
- the vector may represent a utilization of a service, by an already churned customer, during a period of time corresponding to collected data 405.
- An already churned customer may utilize various services and, therefore, have a corresponding number of vectors associated with him or her in customer vector field 420.
- Customer model creator 120 may create the MLMc based on customer table 410. For example, customer model creator 120 may detect and identify various patterns that represent the behavior of already churned customer(s) over the course of a time period.
- MLMc may correspond to a function that may be utilized to classify users (e.g., classify a user(s) as a potential churn customer).
- Data of existing customer(s) may be collected (block 315).
- Data manager 105 may collect data on existing customers.
- data manager 105 may automatically collect data on a customer or a group of customers when one or multiple indications of dissatisfaction occur (i.e., a reactive approach). Additionally, or alternatively, data manager 105 may collect data based on a proactive approach. For example, data manager 105 may periodically or non-periodically collect data.
- data manager 105 may collect data during a first time period (Tl) when an indication of dissatisfaction occurs. Thereafter, data manager 105 may collect data during a second time period (T2).
- Tl first time period
- T2 second time period
- the collected data during time periods Tl and T2 may be utilized by MLS 100 to identify a potential churn customer(s) based on MLMc. That is, the collected data during time periods Tl and T2 may be utilized to identify whether there is a shift in behavior during Tl to T2 that corresponds to a potential churn customer(s). This shift may be identified based on the MLMc. In this way, a potential churn customer(s) may be identified and retention measures may be implemented.
- Customer models MLMTl and MLMT2 may be created (block 320).
- Customer model creator 120 may create MLMTl and MLMT2 in correspondence to the collected data respectively associated with time periods Tl and T2. For example, customer model creator 120 may identify various patterns that represent the behavior of the existing customer(s) over the course of time periods Tl and T2. As will be described below, in some instances, MLMTl and MLMT2 may reflect behavior of a satisfied customer(s). In other instances, MLMTl and/or MLMT2 may reflect behavior of a potential churn customer(s). In one implementation, as described herein, the MLMT2 may be utilized to confirm the prediction of customer behavior associated with the MLMTl . Additionally, the MLMT2 may be utilized to identify a reason behind a shift in behavior between the MLMTl and the MLMT2, assuming a shift exists.
- MLMTl and the MLMT2 may be compared (block 325).
- Customer model comparer 125 may compare MLMTl and MLMT2 to identify whether a transition of customer behavior occurred during the corresponding time periods of Tl and T2.
- Fig. 5A is a diagram illustrating a representation of this comparison. As illustrated in Fig. 5A, the MLMTl and the MLMT2 are depicted, where the x-axis represents time and the y-axis represents customer behavior. In practice, the y-axis may correspond to multi-dimensional indicators associated with a customer's behavior (e.g., utilization of various services, complaints, etc.).
- the comparison between the MLMTl and the MLMT2 may indicate that no transition in behavior has taken place. In other instances, the comparison between the MLMTl and the MLMT2 may indicate that a transition has taken place.
- customer model comparer 125 may generate a vector to represent the transition of customer behavior. For example, customer model comparer 125 may generate mean points 505 and 510, which may correspond to the average of all points in the MLM. Customer model comparer 125 may generate a vector 515 based on mean points 505 and 510. Vector 515 may include, among other characteristics, a magnitude and a direction.
- MLMTl and the MLMT2 may be compared with the MLMc (block 330).
- Customer model comparer 125 may compare MLMTl and MLMT2 with MLMc to determine whether the behavior of customer(s) represented by the MLMTl and the MLMT2 is indicative of a potential churn customer represented by the MLMc.
- Fig. 5B is a diagram illustrating a representation of this comparison. As illustrated in Fig.
- mean points 505 and 510 and vector 515 associated with the MLMTl , and the MLMc and mean point 520 are depicted, where the x-axis represents distance and the y-axis represents customer behavior.
- the y-axis may correspond to multi-dimensional indicators associated with a customer's behavior (e.g., utilization of various services, complaints, etc.).
- customer model comparer 125 may compare a distance 525 between means points 505 and 520 and/or mean points 510 and 520 to determine whether the customer(s) associated with MLMTl and MLMT2 is considered or may be classified as a potential churn customer. Depending on the length of the distance 525 compared to an accuracy measurement decided by a cost function, a determination may be made whether the customer(s) are considered potential churn customer. For example, the shorter the distance, the more likely the customer(s) are moving towards a churn behavior. In one implementation, the accuracy measurement may correspond to a threshold value. The cost function may decide the value(s) associated with the accuracy measurement.
- the accuracy measurement may reduce a prediction error associated with identifying a customer as a potential churn customer. Additionally, or alternatively, the accuracy measurement may regulate one or more metrics associated with how MLMs are formed. For example, the accuracy measurement may impact the clustering and classification of customers. By way of example, the accuracy measurement may provide that customers belonging to a cluster must satisfy the clustering and/or classifying criteria by 95%. Depending on the value(s) of the accuracy measurement, which may be any value, the accuracy of predicting a customer(s) as a potential churn customer may be impacted.
- a vector may be generated by customer model creator 120 or customer model comparer 125 representative of the MLMc.
- the vector associated with the MLMc may be compared with vector 515.
- Fig. 6 is a diagram illustrating a representation of this comparison. As illustrated in Fig. 6, a vector 605 associated with the MLMc may be compared with vector 515. Based on a comparison between vector 515 and vector 605, customer model comparer 125 may generate an angle 610. Depending on the size of angle 610 compared to an accuracy measurement decided by a cost function, a determination may be made whether the customer(s) are considered potential churn customer(s).
- customer model comparer 125 may generate another form of a difference (e.g., magnitude, direction, etc.) between the vectors associated with the MLMc and other MLM(s).
- Potential churn customers may be identified (block 335).
- the existing customer(s) associated with the MLMTl and the MLMT2 may be identified as a potential churn customer(s). For purposes of discussion, process 300 will be described as if the existing customer(s) have been identified as potential churn customer(s).
- Offer creator 130 may formulate new offers based on the behavioral transition between the MLMTl and the MLMT2. For example, in instances when the transition between the MLMTl to the MLMT2 reflects potential churn customer behavior, offer creator 130 may project vector 515 onto the vector space associated with the MLMT2. In this way, a customer vector 420 may be created that constitutes the reason (e.g., a service may be tied to or indicative of a dissatisfaction) associated with the customer's behavior. Offer creator 130 may reference offering registry storage 135 to obtain information relating to the services, rates, etc., currently being offered to the potential churn customer(s).
- reason e.g., a service may be tied to or indicative of a dissatisfaction
- Offer creator 130 may create a new offer(s) that adjusts (e.g., the rate, the amount of allowed usage, etc.) of the service that is tied to the reason. Offer creator 130 may generate a new offer(s) and store them in offering registry storage 135. The new offer(s) may be personalized toward retaining the potential churn customer(s).
- exemplary process 300 may include additional, different, and/or fewer operations than those described in connection with Fig. 3.
- exemplary process 300 may include learning function 1 15 updating customer model creator 120, customer model comparer 125, offer creator 130, and/or other components of MLS 100 based on the accuracy of prediction of potential churn customer(s), retention success, collected data, etc.
- process 300 may create only a single MLM which may be compared to MLMc.
- a MLS may generate customer models to identify potential churn customers. For example, the MLS may utilize a customer model representative of already churned customers to identify potential churn customers as a customer segment. The MLS may provide measurements relating to how the behavior of potential churn customers is evolving toward the behavior of already churned customers. Additionally, the machine learning system may also determine the reason for customer behavior and create appropriate counter measures to address this adverse customer behavior. For example, the MLS may create active measures (e.g., new offers of service) to prevent customers from churning.
- active measures e.g., new offers of service
