Embodiments of the invention provide retailers with the ability to employ concept-based marketing using only a few representative examples. Embodiments of the invention take seed examples, utilize the seed examples to provide an expanded list (that can be edited as desired) representative of the concept, and map the expanded list to a final set of customers to be included in a targeted marketing operation.

A mechanism is provided for two-level guarded predictive power gating of a set of units within the data processing system. A success determines whether a unit within the set of units is power gated during a monitoring interval. If the unit is power gated, the success monitor determines whether a count of idle cycles for the unit is below a breakeven point. If the count is above the breakeven point, the success monitor increments a success efficiency counter. If the count is below the breakeven point, the success monitor determines whether the unit needs to be woke up. If the unit needs to be woke up, the success monitor increments a harmful efficiency counter. If the value of the harmful efficiency counter is less than the value from the success efficiency counter, the success monitor enables power gating for the unit via a first-level power-gating mechanism.

Techniques for automated pricing of an item are provided. The techniques include obtaining historical data of one or more previous purchases for the item, performing a regression on the historical data, and using the regression to obtain a buying price and a selling price for the item.

A method, system, and computer program product for a multi-resolution storage scheme for historical data are provided. The method includes dividing the historical data into a plurality of time frames and determining an amount of compression for each of the time frames, where at least two of the time frames have a different amount of compression. The method further includes applying the amount of compression to each of the time frames, resulting in multi-resolution historical data, and storing the multi-resolution historical data.

A user's preference structure in respect of alternative “objects” with which the user is presented is captured in a multi-attribute utility function. The user ranks these competing objects in order of the user's relative preference for such objects. A utility function that defines the user's preference structure is provided as output on the basis of this relative ranking. This technique can be used to assist a buyer in selecting between multi-attribute quotes or bids submitted by prospective suppliers to the buyer.

Methods and systems for managing energy sources and energy consumers in an integrated system are provided. Certain subject matter presented herein relates to automatically scheduling jobs and their sub-tasks to maximize profit by comparing power source configurations and determining the best job schedule for the power source configurations. This system broadly involves two sub-problems: determining the best power source configuration and determining the best job schedule for the given power source configuration.

Techniques for ranking nodes in a graph are provided. The techniques include computing resultant path strength between each pair of nodes in a polynomial time, determining a first node based on resultant path strength such that total path strength to the first node is a maximum value, iteratively determining a next node from the first node to which the resultant path strength is a maximum value and the node is not visited, and providing each determined node a unique rank value, and ranking the nodes in an order determined by the unique rank value of each node.

Techniques for real-time pricing of electrical energy are provided. The techniques include receiving electrical energy data, wherein the electrical energy data comprises one or more energy pricing parameters specified by an energy supplier, measuring power grid frequency, wherein the power grid comprises the current frequency of the power grid, measuring current energy consumption, wherein current energy consumption comprises total energy consumption in a sampling period, retrieving consumption history, wherein consumption history comprises energy consumed by a customer over a time period, computing a unit energy rate as a function of customer type, the one or more pricing parameters, frequency and past history of consumption, and using the computed rate to compute a total charge as a product of the unit energy rate and the total energy consumption.
摘要:
A window size for outlier detection in a time series of a database system is determined. Strength values are calculated for data points using a set of window sizes, resulting at least in one set of strength values for each window size. The strength values increase as a distance between a value of a respective data point and a local mean value increases. For each set of strength values, a weighted sum is calculated based on the respective set of strength values. A weighting function is used to suppress the effect of largest strength values and a window size is selected based on the weighted sums.
