Abstract: Methods and systems are presented for mining data in association with predicting occurrences of events. Upon detecting an occurrence of an event associated with a transaction, a data mining system accesses data associated with different transactions, and generates a decision tree for predicting occurrences of the event based on the data. Using a classification specification, the data mining system traverses the decision tree and prunes at least a portion of the decision tree that does not satisfy the classification specification. The data mining system then extracts data relevant to predicting occurrences of the event from the pruned decision tree. The extracted data includes attributes and/or criteria that are relevant to predicting occurrences of the event. Based on the extracted data, one or more actions can be performed to improve the event prediction process and/or reduce the frequency of the occurrences of the event.

Abstract: A method includes receiving a payment request that indicates a card identifier corresponding to a payment instrument to be used for payment. The method further includes determining that the card identifiers fails to satisfy at least one card activity criteria. Additionally, method includes subsequent to determining that no failed authorization attempts were performed for the card identifier within a previous time period, retrieving, from a database, a decline probability score associated with the card identifier. The method also includes based on the decline probability score, determining whether to transmit an authorization request for the card identifier prior to processing the payment request.

Abstract: Methods, systems and computer program products for distributed computing systems. Techniques for dynamic service location discovery operate in environments having a first computing system that hosts a client and a second computing system that hosts a service. A service discovery request is transmitted from the first computing system to access a service that is hosted at the second computing system. An IP address corresponding a next IP hop on a route to the IP address of the service is resolved. After traversing the next IP hop, the second computing system that hosts the service receives the service discovery request and responds with an IP address of the service. In accordance with these techniques, the determination of the IP address of the service is performed at a computing system that is different from the first computing system.
