Email 1: Combating Juvenile Delinquency

Subject: Tackling Juvenile Delinquency Together

Hi [Friend's Name],

I hope you're doing well! I wanted to share some thoughts on juvenile delinquency and how we can help prevent it.

딥러닝 핵심 용어 정의 (Brief Definitions)

(i) Training, Validation, Testing Set

• Training Set: 모델의 가중치와 편향을 학습시키기 위해 사용하는 데이터셋입니다.

• Validation Set: 학습 과정 중 하이퍼파라미터 튜닝 및 모델의 성능을 검증하여 과적합 여부를 판단하는 데 사용되는 데이터셋입니다.

• Testing Set: 학습이 완전히 끝난 후, 모델의 최종 성능을 객관적으로 평가하기 위해 사용하는 데이터셋입니다.

(ii) Overfitting (과적합)

모델이 학습 데이터에 너무 과하게 최적화되어, 실제 새로운 데이터(Unseen data)에 대해서는 오차가 커지고 일반화 성능이 떨어지는 현상을 의미합니다.

(iii) Gradient Descent
