가 제공하는 클래스가 마법을 부린다고 느낄만한 부분은 없습니다.
딥러닝을 좀 더 쉽게 할 수 있도록 돕는 기능 조각들을 미리 만들어두었을 뿐이죠! (물론 그 외
에도 여러 가지 추가 기능을 제공합니다. 관련 내용은 차차 알아볼 것입니다. )
다음은 이런 클래스를 활용해서 현재의 선형 모델을 신경망 모델로 바꿔볼 차례입니다.

지금까지 함수의 파라미터를 최적화하는 일반적인 과정과 (약간은 지루한) 단순 선형 분류 모
델을 구현한 함수를 시도해 봤습니다. 선형 분류 모델이 할 수 있는 일에는 한계가 있습니다.
좀 더 복잡한 일을 다루려면 분류 모델을 좀 더 복잡하게 바꿔줘야 합니다. 두 선형 분류 모델

경망이기도 하죠.
다음은 간단한 신경망을 정의한 코드입니다.

res = xb@w1 + b1
res = res.max(tensor(0.0))
