Title: Action estimation device, and program

IPC: G06T7/20
Filed: 2008-08-11
Abstract: <P>PROBLEM TO BE SOLVED: To reduce execution of security control if any action is detected erroneously detected in an action estimation device.  <P>SOLUTION: An action estimation system checks detection future points detected from a photographed image with action estimation models, respectively, by executing estimation action detection processing and detects a specific action as an estimation action so long as it corresponds to an action estimation model having the highest matching degree (S130). If model reliability calculated by model reliability calculation processing is lower than a defined threshold on the basis of an operation signal (i.e., a detection result of a definite action) to be inputted into an image processing processor and the detection result of the estimation action (NO, S150), the system inhibits execution of security control processing in the estimation action detection processing (NO, S180). That is, if the estimation model does not fit a driver of an own vehicle, namely, as the model reliability becomes lower, the system severely restricts execution of control processing.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Title: Bayesian surety check to reduce false positives in filtering of content in non-trained languages
Inventor: COOLEY SHAUN
IPC: G06F13/00
Filed: 2008-08-14
Abstract: <P>PROBLEM TO BE SOLVED: To reduce false positives by using the surety check of Bayesian spam e-mail filtering, when processing an e-mail of a non-trained language.  <P>SOLUTION: A Bayesian spam filter determines an amount of content in incoming e-mail messages that it knows from learning. If the filter is familiar with a threshold amount of the content, the filter proceeds to classify the e-mail message as being spam or legitimate. Meanwhile, if not enough of the words in the e-mail are known to the filter from training, the filter cannot accurately determine whether the message is a spam. In this case, the filter classifies the message as being of an unknown type. Different threshold metrics can be used, such as the percentage of known words, and the percentage of maximum correction value used during processing. This significantly improves the processing of e-mail, in languages which the filter has not learned.  <P>COPYRIGHT: (C)2009,JPO&INPIT
