摘要:
One embodiment of the present invention provides a system that selectively transfers code to a data producer in a networked system. In this system, the data producer generates data and then sends the data to a device. The device receives the data from the data producer, and then uses code on the device to perform a processing operation on the data. Next, the system analyzes characteristics of the data to determine whether performing the processing operation on the data producer can reduce resource usage. If so, the system transfers the code from the device to the data producer, and subsequently executes the code on the data producer. By executing the code on the data producer, the system can optimize resource usage in the networked system.

A recommender system determines a probability threshold for an activity-prediction model, and uses the probability threshold to predict whether a user is performing a target activity. To determine the probability threshold, the system computes a set of activity probabilities based on contextual information for a set of historical activities, and based on an activity-prediction model for a target activity. The system then compares a set of probability thresholds with the set of activity probabilities to determine a prediction success rate for each probability threshold. The system computes a utility score for each probability threshold based on the prediction success rates and a utility function, and selects a probability threshold whose utility score is optimal amongst the utility scores of the set of thresholds and greater than or equal to a baseline utility score. The system then assigns the probability threshold to the activity-prediction model.

Embodiments of the disclosed technology provide a system and method for automatically filling paper form with electronic data. The system receives from a user a scanned image of a paper form that includes a plurality of fields. The system then retrieves a schema map that maps the plurality of fields in the paper form to a plurality of fields in an electronic data record associated with the user. Next, the system retrieves data values of the fields in the electronic data record based on the schema map. The system also synthesizes the retrieved data values and the scanned image to create an image of the paper form in which the fields are filled with the retrieved data values.

One embodiment of the present invention provides a system for recognizing and classifying clothes. During operation, the system captures at least one image of a clothing item. The system further determines a region on the captured image which corresponds to a torso and/or limbs. The system also determines at least one color composition, texture composition, collar configuration, and sleeve configuration of the clothing item. Additionally, the system classifies the clothing item into at least one category based on the determined color composition, texture composition, collar configuration, and sleeve configuration. The system then produces a result which indicates the classification.

One embodiment of the present invention provides a system for facilitating social networking based on fashion-related information. During operation, the system receives fashion-related information from a user. Next, the system extracts the user's fashion preferences from the received information and compares the user's fashion preference with other users' fashion preferences. Finally, the system groups users based on similarity of their fashion preferences.

A mirror system includes an image sensor coupled to a mirror, and gathers consumer shopping preferences for merchandise items. During operation, the system gathers one or more sequential images, from the image sensor, of a consumer wearing a first wearable merchandise item in front of the image sensor. Next, the system identifies in the one or more sequential images a first merchandise item being worn by the consumer. Then, the system determines a demographic group associated with the consumer, and detects behavior patterns for the consumer, wherein the behavior pattern indicates an interest level of the consumer for the identified merchandise item. The system then determines a mapping between the identified consumer demographic group and an interest level for the identified merchandise item, and produces a model which encodes the mapping.

Apparatus and methods are provided for determining a person's compass orientation from data generated by one or more sensors embedded within a portable device transported by the person. Such sensors may include an accelerometer, a GPS (Global Positioning System) receiver, a magnetometer (e.g., a compass), a barometer, etc. In some scenarios (e.g., when the person is walking), the person's initial orientation is directly determined and is used to calculate an initial orientation delta describing a difference between the person's initial orientation and an initial orientation of the device. In other scenarios, the person's current orientation is calculated based on an initial orientation of the device and a known or assumed orientation delta. Later in time, the orientation delta can be applied to the device's current orientation to determine the person's current orientation. As events involving the person and/or the device are observed, an orientation delta may be updated.

One embodiment of the present invention provides a system for determining venue information associated with a mobile device user. During operation, the system collects contextual information recorded by one or more sensors located on the mobile device and extracts a behavior pattern of the user as a function of time and/or an environmental indicator based on the collected contextual information. The system then compares the behavior pattern and/or the environmental indicator with known behavior patterns and/or environmental indicators associated with a number of venues stored in a database, and determines a venue associated with the user based at least on the comparison.

One embodiment of the present invention provides a system for location labeling. During operation, the system collects contextual information recorded by one or more components located on a computing device associated with a user, and determines whether the computing device is stationary based on collected information. Responsive to the computing device being stationary, the system allows the user to provide a location label.
