Outline of Final Research Achievements

Artificial Intelligence generally needs a big data set for its learning. However, in unknown environments, such big data do not exist. To solve this difficulty, we proposed a “collaborative bagging” which is a variation of cloud sourcing technique to make workers solve unknown problems by collaborating with learning machines. For each worker, there is a learning machine that imitates the worker’s behaviors. The solution to candidates from the worker are evaluated according their confidence ratios and translate into a single solution by weighted average. The single solution is used for the feedback-teaching for each worker. As a result, each worker learns the solution to yield better solution candidate in the next time. Therefore, the worker and the learning machine improve their ability gradually by repeating this cycle. Finally, the learning machines become to work as a very excellent problem solver after the latter steps of the learning.

Academic Significance and Societal Importance of the Research Achievements

実用に供される人工知能は、学習に非常に多くの学習データを必要とする。だが未知の領域では学習データそのものが無いため、人工知能は学習ができない。本研究成果は、この問題を解決する一手段を示した。この手法の最もユニーク且つ重要なポイントは、「人」と「人工知能」の両方の能力を高めるという点である。今後人が、人工知能に頼る場面が増えるならば、人はその能力を失う恐れがある。本手法はこれを防ぐ意味で重要である。
