  • Publication number: 20180232706
    Abstract: The present invention relates to a wearable sensor-based automatic scheduling device and method. The wearable sensor-based automatic scheduling device includes: a typical schedule setting part that sets a typical schedule received from the user and specifying a specific event; an atypical schedule inferring part that infers an atypical schedule by analyzing the user's current location and the user's behavioral patterns occurring over a specific period of time in the past; and a schedule determining part that determines the schedule from this point on based on the typical schedule and the atypical schedule. Accordingly, the present invention may provide a technology that can predict the user's expected schedule in real time by taking into account both a typical schedule recorded in a scheduler and an atypical schedule mapped out based on daily behavioral patterns.

  • Patent number: 8520096
    Abstract: Provided are a photographing profile learning apparatus and method of a digital imaging device for recording a personal life history. The photographing profile learning method learns a user's photographing patterns by recommending at least one previous picture consistent with a user's photographing tendencies, using a recommendation function and a user profile based on a user feedback value and a compensation value, receiving user feedback regarding the recommended previous picture, and updating the user profile and the recommendation function according to the user feedback. Therefore, since photographing settings are performed according to a user's tendency and conditions, it is possible to maintain consistency between a currently photographed picture and previously photographed pictures and systematically produce a visual diary.

  • Publication number: 20050272923
    Abstract: Disclosed are a method of predicting mature microRNA regions using a bidirectional hidden Markov model and a medium recording a computer program to implement the method. The method includes representing each base pair comprising the microRNA precursor by state information of match, mismatch and bulge states; representing the base pair by a basepair emission symbol; computing a Viterbi probability (P) for microRNA using a probability (Es(q)) that state s emits symbol q and a transition probability (Tab) from state a to state b; computing a Viterbi probability (Pt(i)) that the i-th base pair is true and another Viterbi probability (Pf(i)) that the i-th base pair is false; and computing a position probability (S(i)) for mature microRNA using the Viterbi probability, wherein, if the position probability (S(i)) for mature microRNA is greater than a predetermined value, the position at which the base pair is present is taken as the mature microRNA region.
