본 논문에서는 의사결정 트리를 기반으로 한 AMR-WB+ 오디오 코더의 코딩 모드 선택 방법을 제안합니다. 좋은 성능을 유지하면서 계산을 줄이기 위해 폐루프 모드 선택 결과를 대상 분류 레이블로 사용하여 의사결정 트리 분류기를 채택합니다. 결정 트리의 크기는 가지치기에 의해 제어되므로 제안하는 방법은 메모리 요구량을 크게 늘리지 않습니다. 음성 및 음악 자료를 모두 포함하는 데이터베이스에 대한 평가 테스트를 통해 제안된 방법은 AMR-WB+의 개방 루프 모드 선택 모듈에 비해 훨씬 더 나은 모드 선택 정확도를 달성하는 것으로 나타났습니다.

Abstract: In this letter, we propose a coding mode selection method for the AMR-WB+ audio coder based on a decision tree. In order to reduce computation while maintaining good performance, decision tree classifier is adopted with the closed loop mode selection results as the target classification labels. The size of the decision tree is controlled by pruning, so the proposed method does not increase the memory requirement significantly. Through an evaluation test on a database covering both speech and music materials, the proposed method is found to achieve a much better mode selection accuracy compared with the open loop mode selection module in the AMR-WB+.
