KNN모델로 장바구니 추천해보기
Shopping Basket Recommendation System with Python
Python을 이용한 장바구니 추천 시스템
Introduction
인공지능은 프로세스를 자동화하고, 비즈니스에 대한 통찰력을 모으고, 프로세스 속도를 높이기 위해 다양한 산업에서 사용되고 있습니다. 인공지능이 실제로 산업에 어떤 영향을 미치는지 실제 시나리오에서 인공지능의 사용을 연구하기 위해 Python을 사용할 것입니다.
장바구니에는 기본적으로 사람이 구매한 아이템 목록이 포함되어 있습니다. 이러한 데이터는 어떤 제품이 수요가 있는지, 어떤 제품이 계절적 상품인지 등과 같은 정보를 나타낼 것이기 때문에 상점에 매우 유용할 정보가 될수 있습니다. 기업은 어떠한 상품에 초점을 맞춰야 하는지 파악하고 이를 바탕으로 추천할 수 있습니다. 장바구니 추천은 AI를 이용해 한 사람의 쇼핑 리스트를 연구해 그 사람에게 구매할 가능성이 있는 물건을 제안할 수 있습니다.
이 노트북에서는 KNN 모델을 사용한 장바구니 추천 시스템에 중점을 둘 것입니다.
Context
[Kaggle]에서 가져온 Amazon 제품 리뷰를 사용하여 작업합니다. Kaggle은 데이터 전문가들이 모여 지식을 공유하고 서로 경쟁하여 보상을 받을 수 있는 데이터 공유 플랫폼입니다.
고객 리뷰 데이터
Amazon, Walmart와 같은 대형 전자 상거래 회사는 매일 수백만 명의 고객과 거래합니다. 고객은 제품을 검색하고 구매하고 때로는 리뷰를 남깁니다. 이를 감안할 때 고객은 전자 상거래 회사에게 가장 중요한 요소입니다: 그들을 지속적으로 만족시켜야 합니다.
고객의 쇼핑 이력, 즉 고객이 무엇을 구매하고 무엇을 선호하는지 알고 있다고 상상해 보십시오. 당신은 그들이 미래에 무엇을 사고 싶어할지 예측하고 그러한 것들을 제안함으로써 이 정보를 당신에게 유리하게 사용할 수 있습니다.
Side note: KNN 이란?
KNN(K-Nearest Neighbors)은 분류와 회귀에 모두 사용되는 알고리즘입니다. KNN 알고리즘은 ‘유유상종’이라는 말처럼 주변에 비슷한 것이 존재한다고 가정한다. KNN 알고리즘은 가장 가까운 이웃의 클래스, 특히 k 수를 기반으로 새 데이터 포인트를 분류합니다. k는 객체의 클래스를 결정하는 데 도움이 되는 가장 가까운 이웃의 수를 나타냅니다. 다음 다이어그램에서 명확하게 확인할 수 있습니다.
Types of recommendations
There are mainly 6 types of the recommendations systems :-
-
Popularity based systems :- It works by recommeding items viewed and purchased by most people and are rated high.It is not a personalized recommendation.
-
Classification model based:- It works by understanding the features of the user and applying the classification algorithm to decide whether the user is interested or not in the prodcut.
-
Content based recommedations:- It is based on the information on the contents of the item rather than on the user opinions.The main idea is if the user likes an item then he or she will like the “other” similar item.
-
Collaberative Filtering:- It is based on assumption that people like things similar to other things they like, and things that are liked by other people with similar taste. it is mainly of two types:
a) User-User
b) Item -Item
-
Hybrid Approaches:- This system approach is to combine collaborative filtering, content-based filtering, and other approaches .
-
Association rule mining :- Association rules capture the relationships between items based on their patterns of co-occurrence across transactions.
Use Python to open csv files
scikit-learn, pandas, matplotlib를 사용하여 데이터 세트를 작업합니다. Scikit-learn은 예측 데이터 분석을 위한 효율적인 도구를 제공하는 매우 유용한 기계 학습 라이브러리입니다. Pandas는 데이터 과학을 위한 인기 있는 Python 라이브러리입니다. 강력하고 유연한 데이터 구조를 제공하여 데이터 조작 및 분석을 더 쉽게 만듭니다. Matplotlib은 고품질의 데이터 시각화를 위한 Python의 2차원 그래프 라이브러리입니다. 코드 몇 줄만으로 간단하게 복잡한 그래프를 만들 수 있어서 사용성이 매우 높습니다.

분위수 분포 보기
분위수는 샘플을 동일한 크기의 그룹으로 나누는 지점입니다. 정렬된 데이터 집합의 중앙값은 해당 집합의 중간 지점으로 정렬은 오름차순 또는 내림차순으로 정렬됨을 의미합니다. 따라서 중앙값은 데이터 세트를 2개의 동일한 그룹으로 나눌 때 분위수입니다.

KNN 기능이 있는 Surprise 라이브러리를 import 시킵니다. 인기가 적은 상품은 추천에 크게 영향을 주지 않기 때문에 어떤 상품이 사용자에게 정말 인기가 있는지 확인하고 새로운 상품을 추천할 때 사용합니다.
라이브러리가 설치되어 있지 않은 경우 터미널에서 다음 단계를 수행하십시오.

Getting accuracy
정확도
기계 학습 알고리즘의 정확도는 알고리즘이 얼마나 잘 수행되고 있는지, 즉 알고리즘이 데이터 포인트를 올바르게 분류하는 빈도를 측정하는 것입니다. 정확도는 다음과 같이 주어집니다:
상관 행렬
상관 행렬은 변수 간의 관계, 즉 다른 변수가 변경될 때 한 변수가 어떻게 변경되는지를 보여주는 테이블입니다. 5개의 변수가 있는 경우 상관 행렬에는 5 곱하기 5 또는 25개의 항목이 있으며 각 항목은 두 변수 간의 상관 관계를 보여줍니다.
RMSE
RMSE는 평균 제곱근 오차를 나타냅니다. 기계 학습 모델을 사용하여 예측을 수행할 때 예측이 정확한지 확인해야 합니다. RMSE는 예측 오류를 측정하는 방법입니다. RMSE가 높으면 예측이 나쁘고, 낮으면 예측이 좋은 것입니다.
# RMSE를 구합니다.
print("Item-based Model : Test Set")
accuracy.rmse(test_pred, verbose=True)
Item-based Model : Test Set RMSE: 1.3317
1.3316598350472562
우리의 최종 목표는 예측 모델을 얻는 것입니다. 기존 사용자-항목 상호 작용을 이용하여 사용자에게 가장 적합할 수 있는 상위 5개 항목을 예측하도록 모델을 훈련할 수 있습니다. 상위 10000개의 추천 항목과 SVD 알고리즘을 사용하는 모델을 사용하겠습니다.

마무리
-
각 설치 문제건등으로 인해서 어쩔 수 없이 이후에 정리해서 마무리;;
-
그래도 결과는 나왔으나 어디서 뭔가 빼먹었는지 수치가 높게 나오는 문제가 있음.
-
겉으로는 정상작동되어보임.. 다만, 제대로 작동하는지는..(만일 문제가 있다면 수정이 필요..)
-
이번 과제를 보면서 오히려 KMM보단 어떻게 아나콘다에서 라이브러리를 관리할까의 과제를 고민하게 되었달까.
