あらまし Q-learning と Actor-Critic アーキテクチャ の Actor を組み合わせた Actor-Q アーキテクチャと それを用いた能動認識学習システムを提案する.Actor-Q アーキテクチャは,システムの出力を,離散的な意思 である「行動」と連続値である「動作」に区別し,まず,Q値を用いて「行動」を決定し,その「行動」が「動作」 を伴う場合には,さらに,該当する Actor の出力にしたがって「動作」を行う.そして,Q値は,Q-learning で学習し,Actor は,その「行動」に対応するQ値を Criticの出力として学習を行なう. ここでは,センサの移動および各パターンであるという認識の結論を下すことを行動とし,それぞれに Q値を割 り当てる.そして,センサの移動が選択された際は,Actor の出力にしたがってセンサを移動する.認識が選択 された場...

This study explores and describes different viewpoints on Computer Based Assessment (CBA) by using Q methodology to identify perspectives of students and instructors and classify these into perceptional typologies. Thirty undergraduate students taking CBA courses and fifteen instructors adopting CBA into their curriculum at a university in Korea, were chosen as participants in this study. As a ...

This report is an output from a project funded by the UK Department for International Development (DFID) for the benefit of developing countries under its Natural Resources Systems Programme (project no R8280).

more leisure, and with access to better material and instruments, than the writer can at present avail himself of. As apology for its incompleteness, I can only plead the stress and strain of active service, coupled with separation from the records of all experiments made in connection with the subject. It is hoped that on the return of the China Field Force to India that opportunity will be af...

A quantitative TaqMn Real-Time PCR assay was developed and its diagnostic value on human serum and livestock samples were evaluated. Brucella species could be distributed through communities as a biological agent. Rapid detection of biological threat agents is critical for timely therapeutic administration. Quantitative real-time PCR provides a rapid, sensitive and specific tool for molecular i...
