A Logistic Regression Model for Intraoperative Hypotension Prediction

This paper presents a study on using a logistic regression model for the prediction of intraoperative hypotension, a common but critical situation occurring during surgeries where the patient's blood pressure drops significantly.


This paper presents a study on using a logistic regression model for the prediction of intraoperative hypotension, a common but critical situation occurring during surgeries where the patient's blood pressure drops significantly. The model was developed using the Python scikit-learn library and was trained on 80% of the available data, while the remaining 20% was used for testing and evaluation. After preprocessing the data, the logistic regression model was trained and then predicted the occurrence of hypotension. The model demonstrated high accuracy, with 97.92% for predictions one minute ahead, but a slight decrease in accuracy was observed as the prediction time increased. When personalized for this type of surgery, the model's performance improved for only a few surgeries, otherwise not highlighting the efficacy of an individualized approach. However, the model faced limitations in predicting hypotensive events beyond a few minutes in advance, necessitating future exploration of more advanced machine learning models. While the logistic regression model's performance was promising, other machine learning models like gradient boosting and random forest algorithms also show high potential. The research underscores the potential of machine learning models in enhancing patient safety and optimizing surgery outcomes through accurate prediction of intraoperative hypotension.This paper presents a study on using a logistic regression model for the prediction of intraoperative hypotension, a common but critical situation occurring during surgeries where the patient's blood pressure drops significantly.

Skin Cancer Detection

The goal of this research project is to predict whether or not a patient has skin cancer through a machine learning model that is developed from an image dataset. Skin cancer is extremely dangerous, as over 9500 people in the US are diagnosed with it daily. If detected early, patients will have a more likely chance of survival. I tested an MLP Classifier, Decision Tree Regressor, a Logistic Regression Model, and a KNN Model to compare various results and ultimately determine the best accuracy. The MLP Classifier had a 74.5% accuracy, the Decision Tree Regressor had a 74.1% accuracy, the Logistic Regression Model had a 68.8% accuracy, and the KNN Model had a 74.6% accuracy (all testing). We can see that the MLP Classifier, Decision Tree Regressor, and the KNN Model had around the same accuracy while outperforming the Logistic Regression Model. However, when comparing training data, there seems to be a large overfitting problem with most of the models.

Does Physiology Really Help a Volleyball Player Succeed?

As a child, I always went to my sister’s volleyball games. From club games to school games, I went to them all. Because I saw so many volleyball games by watching my sister’s games, I always saw that there was always a trend that I kept seeing from each team.
