O’Reilly covers everything we've got, with content to help us build a world-class technology community, upgrade the capabilities and competencies of our teams, and improve overall team performance as well as their engagement.I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.

케라스로 모델 개선하기
이 절에서는 케라스를 사용하여 자동차 경매 판매 가격 문제에 대한 다양한 신경망 모델 구조
를 살펴봅니다. 앞서 살펴본 특징 선택 및 특징 공학을 그대로 재사용하지 않고, 사이킷런에서
사용한 변환기와 유사한 케라스 전처리 계층을 소개합니다. 사이킷런 파이프라인의 특징 공학
부분을 케라스로 재현한 다음에는 케라스 튜너
Keras
Tuner
패키지와 앞 절에서 설명한 베이지안 최
적화 방법을 사용하여 하이퍼파라미터 튜닝을 수행하는 방법을 배우게 됩니다.
8.3.1
케라스의 전처리 계층
케라스의 전처리 계층을 사용하면 사이킷런에서 파이프라인을 만든 것과 같은 방식으로 데이
터 전처리 함수를 모델에 쉽게 포함할 수 있습니다.

장과 앞 절에서 전처리 로직을 모델 자체
에 포함하면 얼마나 편리한지 살펴보았습니다. 앞 절에서는 모델을 저장하지는 않았지만,

에서처럼
joblib
라이브러리를 활용하면 학습된 파이프라인 전체를 쉽게 저장할 수 있습니다.
앞 절에서 데이터셋에 수행한 변환을 다시 생각해 보겠습니다. 범주형 특징을 원핫 인코딩하

필요한 전처리 계층을 먼저 이해하면 좋습니다.
