          <datacite:description descriptionType="Other">視覚情報のみを用いて発話内容を推定する読唇技術は，教師あり学習の一種であり，大規模なデータセットが望まれている．しかし，発話シーンの収集はコストがかかる問題がある．そこで本論文では，収集コストを抑えるために，少数データで学習するアプローチの中で，メタ学習を用いる手法を検討する．読唇用公開データセット LRW および SSSD，比較用として行動認識公開データセット UCF101 の三つのデータセットを用いて，ProtoNet や DeepBDC など幾つかのメタ学習手法を用いて認識実験を実施した．その結果，UCF101 に比べると LRW とSSSD では低い認識精度であった．本稿では実施した実験結果を報告する．</datacite:description>
          <datacite:description descriptionType="Other">Lip-reading technology, which estimates utterance content using only visual information, is a kind of supervised learning, and a large-scale data set is desired. However, collecting utterance scenes is costly. Therefore, in this paper, in order to reduce the collection cost, we consider a method that uses meta learning in the approach of learning with a small number of data. Recognition experiments were conducted using several meta learning methods such as ProtoNet and DeepBDC using three datasets: public datasets LRW and SSSD for lip-reading, and public action recognition dataset UCF101 for comparison. As a result, compared to UCF101, LRW and SSSD had lower recognition accuracy. In this paper, we report the experimental results.</datacite:description>
