摘要:
Systems and methods for processing Machine Learning (ML) algorithms in a MapReduce environment are described. In one embodiment of a method, the method includes receiving a ML algorithm to be executed in the MapReduce environment. The method further includes parsing the ML algorithm into a plurality of statement blocks in a sequence, wherein each statement block comprises a plurality of basic operations (hops). The method also includes automatically determining an execution plan for each statement block, wherein at least one of the execution plans comprises one or more low-level operations (lops). The method further includes implementing the execution plans in the sequence of the plurality of the statement blocks.

A process of transforming data residing in databases, such as relational databases, into forms suitable as input to data analysis tools, such as predictive modeling tools includes the steps of defining a business process problem to be solved and identifying data requirements. For example, the business process problem may relate to predicting a customer's propensity to make purchases in the future or a store's requirements for inventory in the future. In the process, a computer implemented method is used for automatically transforming data for data analysis such as predictive modeling. Database metadata that describe database tables, their interrelationships, dimensional information, fact tables and measures are accessed. A mining transformation profile is created to encapsulate aggregations and transformation on data stored in relational databases in order to convert the data to forms suitable for predictive mining tools. The mining transformation profile specifies data transformations relative to the data base metadata. Executable data transformation codes is then generated from the database metadata and the mining transformation profile. Execution of this code results in aggregation and transformation of data residing in a database for input to a data analysis tool such as a predictive modeling tool. The data transformation code can be used by, for example, the predictive modeling tool to generate an output that provides a solution to a business process problem.

The present invention employs data processing systems to handle debt collection by formulation the collections process as a Markov Decision Process with constrained resources, thus making it possible automatically to generate an optimal collections policy with respect to maximizing long-term expected return throughout the course of a collections process, subject to constraints on the available resources possibly in multiple organizations. This is accomplished by coupling data modeling and resource optimization within the constrained Markov Decision Process formulation and generating optimized rules based on constrained reinforcement learning process comprising applied on the basis of past historical data.

A method of marketing optimization with respect to brand lifetime management formulates a problem of brand equity maximization utilizing Markov Decision Process (MDP) thereby casting brand equity management as a long term regard optimization problem in MDP, The marketing mix is optimized by formulating the mix as actions in MDP and, utilizing historical marketing and transaction data, aspects of the MDP are estimated.

A security slider for a zip fastener which prevents or severely restricts unauthorised access to the contents of an item which is closed by the zip fastener. This is achieved by a lateral blocking member attached to the slider. A zip fastener incorporating the slider and a suitcase or bag incorporating the zip fastener are also provided.
摘要:
A method, and system for targeted marketing of goods or services to specific customers is disclosed. Customers are analyzed based upon historical criteria; a promotional plan (a group of promotion events implemented or to be implemented over a particular time period) is analyzed to determine the effect of each promotion event on the other promotion events in the promotional plan; and, based on this analysis, the optimal promotion stream (a specific subset of the promotional plan to be sent to customers or a group of similar customers) is determined so as to maximize the ROI of the promotional plan as a whole.
摘要:
A flat heat exchanger plate typically used in a bulk material heat exchanger is provided. The flat heat exchanger plate is designed to operate under a negative internal pressure to eliminate depressions or dimples that are typically formed into the sides of these types of heat exchanger coils during the manufacture process. With the removal of the depressions or dimples the tendency for bulk material to accumulate to the exterior surface of the plate is reduced, thereby increasing the service period of the plate.
摘要:
Streaming media network transportation streams are created using an electronic system and transmitted via an electronic interface such as an existing system network conduit (i.e. Ethernet, USB, or other packet-based architectures). A scalable hardware and/or software compute engine modifies an initial stream's identifier(s) while replicating the stream content to economically create streams. Hence, an entire network's capacity of active streams may be created from a single initial stream. In one example, an initial stream is stored in advance of transmission for such use. In other examples, an initial stream is received and processed to dynamically create streams from the initial stream as the initial stream is being received.

A flat plat plate heat exchanger coil typically used in a bulk material heat exchanger is provided. The flat plate heat exchanger coil is designed to operate under a negative internal pressure to eliminate depressions or dimples that are typically formed into the sides of these types of heat exchanger coils during the manufacture process. With the removal of the depressions or dimples the tendency for bulk material to accumulate to the exterior surface of the coil is reduced, thereby increasing the service period of the coil. The flat plate is also provided with methods of automated cleaning of the plate coil, such as applying a low positive internal pressure in a cyclic manner to dislodge material accumulated on the coil, bumping the coil to causing a shock wave through the coil or providing means to create a shearing effect between adjacent coils to dislodge material accumulated on the exterior of the coil.
摘要:
A method for constructing predictive models that can be used to make predictions in situations where the inputs to those models can have values that are missing or are otherwise unknown. The method can realize significant advantages because it can be readily applied in conjunction with any method for constructing models, including ones that require all input values to be known, thereby yielding combined methods for constructing models that tolerate missing values.
