Stride

  • filer의 이동 간격 (보폭)을 조절하는 것

  • Stride = 2
  • input : \( n \times n\)
  • filter : \( f \times f \)
  •  padding : \( p \)
  • stride : \(s\)
  • output : \(\left \lfloor \frac{n+2p-f}{s}+1\right \rfloor\times \left \lfloor\frac{n+2p-f}{s}+1\right \rfloor  \) -> 소수로 나올시 내림
    • filter가 딱맞지 않게 떨어지면 계산을 안하기 위해서 -> 보통은 딱 떨어지게 설정함
