The xgboost does better slightly better than the random forest and logistic regression, however the results are all close to each other. University of British Columbia. 1999. ejection fraction, 48 restwm: rest wall (sp?) Red box indicates Disease. University Hospital, Zurich, Switzerland: William Steinbrunn, M.D. NIPS. However, the column 'cp' consists of four possible values which will need to be one hot encoded. Although there are some features which are slightly predictive by themselves, the data contains more features than necessary, and not all of these features are useful. AMAI.

The f value is a ratio of the variance between classes divided by the variance within classes. To do this, I will use a grid search to evaluate all possible combinations.

After reading through some comments in the Kaggle discussion forum, I discovered that others had come to a similar conclusion: the target variable was reversed. 1996.

Upon applying our model to the testing dataset, I manage to get an accuracy of 56.7%. The names and descriptions of the features, found on the UCI repository is stored in the string feature_names. This week, we will be working on the heart disease dataset from Kaggle. Hungarian Institute of Cardiology.

Since any value above 0 in ‘Diagnosis_Heart_Disease’ (column 14) indicates the presence of heart disease, we can lump all levels > 0 together so the classification predictions are binary – … Step 4: Splitting Dataset into Train and Test set To implement this algorithm model, we need to separate dependent and independent variables within our data sets and divide the dataset in training set and testing set for evaluating models. The University of Birmingham. 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. The dataset used for this work is from UCI Machine Learning repository from which the Cleveland heart disease dataset is used. We can also see that the column 'prop' appear to both have corrupted rows in them, which will need to be deleted from the dataframe. Totally, Cleveland dataset contains 17 attributes and 270 patients’ data. (c)2001 CHF, Inc. motion abnormality 0 = none 1 = mild or moderate 2 = moderate or severe 3 = akinesis or dyskmem (sp?) In addition the information in columns 59+ is simply about the vessels that damage was detected in. For example,the dataset isn't in standard csv format, instead each feature spans several lines, with each feature being separated by the word 'name'. Artificial Intelligence, 40, 11--61. Department of Computer Methods, Nicholas Copernicus University. It is integer valued from 0 (no presence) to 4. Skewing: An Efficient Alternative to Lookahead for Decision Tree Induction. Heart disease risk for Typical Angina is 27.3 % Heart disease risk for Atypical Angina is 82.0 % Heart disease risk for Non-anginal Pain is 79.3 % Heart disease risk for Asymptomatic is 69.6 % University Hospital, Zurich, Switzerland: William Steinbrunn, M.D. 1999.

The xgboost is only marginally more accurate than using a logistic regression in predicting the presence and type of heart disease. These will need to be flagged as NaN values in order to get good results from any machine learning algorithm. Elevation of CRP is associated with several major coronary heart disease risk factors and with unadjusted and age-adjusted projections of 10-year coronary heart disease risk in both men and women.
