  • Publication number: 20170147949
    Abstract: A method of inverse reinforcement learning for estimating reward and value functions of behaviors of a subject includes: acquiring data representing changes in state variables that define the behaviors of the subject; applying a modified Bellman equation given by Eq. (1) to the acquired data: r ? ( x ) + ? ? ? V ? ( y ) - V ? ( x ) = ? ln ? ? ? ? ( y | x ) b ? ( y | x ) , ? ( 1 ) = ? ln ? ? ? ? ( x , y ) b ? ( x , y ) - ln ? ? ? ? ( x ) b ? ( x ) ,                                                ? ( 2 ) where r(x) and V(x) denote a reward function and a value function, respectively, at state x, and ? represents a discount factor, and b(y|x) and ?(y|x) denote state transition probabilities before and after learning, respectively; estimating a logarithm of the density ratio ?(x)/b(x) in Eq.

  • Publication number: 20160310593
    Abstract: Provided is a method for controlled release of a chemical substance in vivo with femtosecond laser pulses. The method comprises a step of injecting into the body of a subject a liposome which is filled with the chemical substance and attached to metal nanoparticles. Then, a laser pulse train is applied to the liposome from outside the body with a constant or variable laser intensity, exposure time and time between exposures, thereby releasing a controlled amount of the chemical substance in the body from the liposome on a timescale fast enough to reproduce neural signaling.
