처음 봤을 땐 첫 번째 시퀀스가 짧기 때문에 더 쉬워 보입니다. 하지만 두 번째 시퀀스를 자세
히 살펴보면
50
부터
14
까지 짝수를 나열했다는 걸 알 수 있습니다. 이런 패턴을 알고 나면 첫
번째보다 두 번째 시퀀스를 외우는 것이 더 쉽습니다. 패턴 (줄어드는 짝수), 시작 숫자, 종료
숫자 (
50
과

)만 외우면 됩니다. 무엇이든 빠르고 쉽게 기억할 수 있는 사람이라면 두 번째
시퀀스에 어떤 패턴이 있는지 신경 쓸 필요가 없습니다. 모든 숫자를 외우면 그만이니까요. 하
지만 보통 이렇게 긴 시퀀스를 기억하기 어렵기 때문에 패턴을 찾는 것이 유용합니다. 그렇기
때문에 훈련하는 동안 오토인코더에 제약을 가해서 데이터에 있는 패턴을 찾아 활용합니다.
