摘要:
A user may be exposed to multiple token instances representing stimuli that may influence the affective state of the user. Described herein are embodiments of systems, method, and computer programs for estimating affective response to a token instance of interest, selected from among the token instances. In one example embodiment, the token instance of interest is a token instance for which attention level of the user is higher than at least one other token instance.

A system, method, and computer product for reducing volume of transmissions of measurements of affective response are described herein. In one embodiment, an interaction analyzer receives a description of an interaction of a user with a media controller that controls presentation of content to the user. The interaction analyzer identifies from the description an action that causes a deviation from a progression of presentation of the content that would have occurred had the action not taken place. A transmitter sends a request to transmit measurements of affective response, taken by a sensor, during a window during which the user likely expressed an affective response related to the action. In some embodiments, the request is received by a transceiver coupled to the sensor with memory sufficient to store measurements of affective response of the user taken since the start of the window, which precedes the time the request is sent.
摘要:
Systems and methods for reducing the computational load of processing measurements of affective response of a user to content. A content emotional response analyzer (content ERA) receives a segment of content, analyzes it, and outputs an indication regarding whether a value related to a predicted emotional response to the segment reaches a predetermined threshold. Based on the indication, a controller selects a processing level, from among at least first and second processing levels, for a processor to process measurements of affective response. The first level may be selected when the value does not reach the predetermined threshold, while the second level may be selected when the value reaches it. The processor is configured to utilize significantly fewer computation cycles to process data operating at the first processing level, compared to the number of computation cycles it utilizes to process data operating at the second processing level.

Systems and methods for reducing power consumption of a device utilized to measure affective response to content by overriding selections of a mode-selector. The mode-selector receives tags corresponding to segments of content. The mode-selector selects, based on the tags, modes for operating the device to measure affective response to the segments. A threshold module receives measurements of the user's state, taken by a sensor, and indicates whether a predefined threshold is reached by the measurements. If reached, the device is operated according to a first mode to measure the affective response. Otherwise, the device is operated according to a second mode to measure the affective response. The power consumption of the device when operating in the second mode is significantly lower than the power consumption of the device when operating in the first mode.

Described herein are methods for training a machine learning-based predictor of affective response to stimuli. The methods involve receiving samples comprising temporal windows of token instances to which a user was exposed, and target values representing affective response annotations of the user in response to the temporal windows of token instances. This data is used for the training of the predictor along with values indicative of the number of the token instances in the temporal windows of token instances, which are used to compensate for non-linear effects resulting from saturation of the user.
摘要:
An assembling device obtaining enough erasure-coded fragments from fractional-storage CDN servers for reconstructing a first set of segments including at least one segment. The communication between the assembling device and the servers is subject to at least one type of communication fault, and the assembling device handles the communication faults by approximately randomly selecting on-the-fly servers from which to obtain additional fragments instead of fragments that failed to be obtained.

A network comprising an authentication network limited to a family dwelling; a content source; and a content receiver. Wherein the content source is configured to transmit encrypted content to the content receiver, and the content receiver can decode the encrypted content only when both the content source and the content receiver are physically connect to the authentication network.

Estimating a response to a token instance of interest, including the steps of: receiving token instances to which a user was exposed, receiving a total response of the user to the token instances; receiving attention levels of the user in the token instances; selecting the token instance of interest from among the token instances based on the attention level; and estimating the response to the token instance of interest from the total response.

Predicting a user's response to a stream of token instances, including: receiving a stream of token instances; partitioning the stream of token instances into consecutive temporal windows of token instances; predicting response of the user to temporal windows of token instances; predicting response of the user to a certain temporal window of token instances; and forwarding the prediction of the user to the stream of token instances.
摘要:
Calculating a situation-dependent baseline value for a user response to token instances representing stimuli that influence the user's affective state, utilizing large time windows and rapid adjustments to changing situations, including: accessing a database storing annotations representing the user's response to token instances originating from multiple distinct token sources; calculating a first situation-dependent baseline value by weighting annotations retrieved from the database and associated with a first situation identifier, which are spread over a long period of time ‘T’; calculating a second situation-dependent baseline value by weighting annotations retrieved from the database and associated with a second situation identifier; wherein the difference between the first and second situation-dependent baseline values is significant, and the method rapidly adjusts to the situation change by exhibiting an extremely shorter transient time between the first and the second situation-dependent baselines than T/2
