Publication number: 20140114734Abstract: Techniques are provided for determining, by a coupon distributor, a value for a coupon of a product or service that will be provided by a coupon provider. The coupon provider provides, to the coupon distributor, one or both of a budget value that indicates an amount the coupon provider is willing to pay the coupon distributor for distributing the coupon, and a redemption rate that indicates one or more target redemption rates. The coupon provider uses a coupon value equation to calculate the coupon value based on a budget value and a redemption rate. The coupon provider might estimate that no coupon value will allow the coupon provider to stay within the budget and ensure that the actual redemption rate will be close to a particular redemption rate, which may or may not be specified by the coupon distributor.Type: ApplicationFiled: December 24, 2013Publication date: April 24, 2014Applicant: Coupons.com incorporatedInventors: Deepak Goel, Kavel Patel, Sajjit Thampy

Publication number: 20140074649Abstract: State-based approaches, techniques, and mechanisms are disclosed for recommending items to a user. A method comprises detecting a user state, from a plurality of different enumerated user states, based on items that the user recently selected, and/or location data. Based upon the detected user state, a particular algorithm, from a plurality of algorithms, is selected for recommending items. Information about the recommended items is presented to the user. Responsive to presenting the information about the recommended items, input is received selecting one or more of the recommended items for at least one of: adding to a shopping list, or requesting a coupon. Examples of possible detected user states include a recipe state, a grocery shopping state, and a quick shopping-run state. In an embodiment, state detection occurs at a client device, such as a smartphone featuring a shopping list management application or coupon application. A server-side recommendation engine provides recommendations.Type: ApplicationFiled: September 13, 2012Publication date: March 13, 2014Applicant: Coupons.com IncorporatedInventors: Kavel Patel, Sajjit Thampy

Patent number: 8560384Abstract: Techniques are provided for generating, by a coupon distributor, a score that represents a quality of a coupon campaign that a coupon provider offers to the coupon distributor. The score may be generated based on the brand of the product, the product category to which the product belongs, the coupon value, and the percentage discount reflected by the coupon. One or more of these factors may be based on historical data that indicates the success (or failure) of previous coupon campaigns (e.g., of the same product, brand, and/or product category, and/or similar coupon value). The coupon distributor uses the score to, e.g., determine whether to accept a proposed coupon campaign, project the number of prints/redemptions of the coupon campaign, determine how to present the coupon, determine an amount to charge for running the coupon campaign, and/or determine products or product categories of coupons to which the coupon distributor should seek.Type: GrantFiled: January 6, 2012Date of Patent: October 15, 2013Assignee: Coupons.com IncorporatedInventors: Kavel Patel, Sajjit Thampy

Patent number: 7716648Abstract: A system that identifies processes with a memory leak in a computer system. During operation, the system periodically samples memory usage for processes running on the computer system. The system then ranks the processes by memory usage and selects a specified number of processes with highest memory usage based on the ranking. For each selected process, the system computes a first-order difference of memory usage by taking a difference between the memory usage at a current sampling time and the memory usage at an immediately preceding sampling time. The system then generates a memory-leak index based on the first-order difference and a preceding memory-leak index computed at the immediately preceding sampling time.Type: GrantFiled: August 2, 2005Date of Patent: May 11, 2010Assignee: Oracle America, Inc.Inventors: Kalyanaraman Vaidyanathan, Sajjit Thampy, Kenny C.

Patent number: 7573952Abstract: One embodiment of the present invention provides a system that resamples a quantized signal. During operation, the system receives the quantized signal. Next, the system smoothes and resamples the quantized signal to produce a resampled signal. The system then quantizes the resampled signal to produce a quantized resampled signal. For a given time point, the system determines a probability distribution for the resampled signal across quantization levels at the given time point by using information about the values of the resampled signal at neighboring time points. Note that the probability distribution specifies the probability that the resampled signal would be sampled at specific quantization levels. The system then uses the probability distribution to probabilistically select a quantization level for the resampled signal for the given time point.Type: GrantFiled: August 23, 2005Date of Patent: August 11, 2009Assignee: Sun Microsystems, Inc.Inventors: Sajjit Thampy, Kenny C.

Patent number: 7542995Abstract: A system that detects a change point in a time series of telemetry signals from a computer system. During operation, the system receives the time series of telemetry signals from the computer system. For each element in the time series, the system (1) inserts the element into a data structure which keeps track of the number of elements in the data structure that have a value greater than and that have a value less than the value of the inserted element; and (2) uses the information stored in the data structure to add a contribution by the inserted element to a trend statistic for the time series. The system then uses the trend statistic to select a hypothesis for the trend in the time series.Type: GrantFiled: April 11, 2006Date of Patent: June 2, 2009Assignee: Sun Microsystems, Inc.Inventors: Sajjit Thampy, Kenny C.

Publication number: 20090113288Abstract: Disclosed herein is a statistical approach, a win share approach, used to assign a win share value to content items. User interaction with content items is tracked, and a win share value is assigned to content items in response to a “winning” action performed by a user. Win shares associated with content items are used to identify content items that are to be presented, and can further be used to identify an optimal presentation, e.g., layout, presentation frequency, etc., of content items that is to be presented.Type: ApplicationFiled: December 21, 2007Publication date: April 30, 2009Inventors: Sajjit Thampy, Daniel Ferrante, Amr Awadallah

Publication number: 20090055200Abstract: Techniques are described herein for an automatic discovery and validation analyzer that identifies factors that have a particular effect on members of a population in engaging in certain activities. A baseline set and a divergent set of members of the population are identified based on whether a member has experienced a significant change in magnitude of the particular effect during a particular period of time. Differences in behaviors of members of the baseline and divergent sets are then analyzed to identify a candidate factor that corresponds to exposure to an item. Such a candidate factor is then validated as to whether it is a cause of said significant change in magnitude of the particular effect experienced by the divergent set of members.Type: ApplicationFiled: August 20, 2007Publication date: February 26, 2009Applicant: YAHOO!
