Lot of work has been carried out to predict heart disease using UCI … This week, we will be working on the heart disease dataset from Kaggle. This paper presents performance analysis of various ML techniques such as Naive Bayes, Decision Tree, Logistic Regression and Random Forest for predicting heart disease at an early stage [3]. For this purpose, we focused on two directions: a predictive analysis based on Decision Trees, Naive Bayes, Support Vector Machine and Neural Networks; descriptive analysis … 2002.

Some columns such as pncaden contain less than 2 values. 2001. The description of the columns on the UCI website also indicates that several of the columns should not be used. Each dataset contains information about several patients suspected of having heart disease such as whether or not the patient is a smoker, the patients resting heart rate, age, sex, etc. However, only 14 attributes are used of this paper. However, the column 'cp' consists of four possible values which will need to be one hot encoded. 2002. 1999. Data Eng, 12.

In particular, the Cleveland database is the only one that has been used by ML researchers to this date.

I will also one hot encode the categorical features 'cp' and 'restecg' which is the type of chest pain. Our algorithm already selected only from these 14 features, and ended up only selecting 6 of them to create the model (note cp_2 and cp_4 are one hot encodings of the values of the feature cp). When I started to explore the data, I noticed that many of the parameters that I would expect from my lay knowledge of heart disease to be positively correlated, were actually pointed in the opposite direction. #32 (thalach) 9.
