    Abstract: A method of inverse reinforcement learning for estimating cost 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: q(x)+gV(y)−V(x)=−1n{pi(y|x))/(p(y|x)} (1) where q(x) and V(x) denote a cost function and a value function, respectively, at state x, g represents a discount factor, and p(y|x) and pi(y|x) denote state transition probabilities before and after learning, respectively; estimating a density ratio pi(y|x)/p(y|x) in Eq. (1); estimating q(x) and V(x) in Eq. (1) using the least square method in accordance with the estimated density ratio pi(y|x)/p(y|x), and outputting the estimated q(x) and V(x).

    Abstract: A method of forming crystallized semiconductor particles includes: forming amorphous semiconductor particles in a vacuumed aggregation chamber; transporting the amorphous semiconductor particles formed in the vacuumed aggregation chamber to a vacuumed deposition chamber within which a substrate is held; and applying a vapor of a metal catalyst to the amorphous semi-conductor particles while still in transit to the substrate in the vacuumed deposition chamber to induce crystallization of at least portion of the amorphous semiconductor particles via the metal catalyst in the transit, thereby depositing the crystallized semiconductor particles with the metal catalyst attached thereto onto the substrate.
