Predicting Heart Disease using Machine Learning Algorithms [PDF]

Mathematics Association of Cambodia (MAC)
Online Seminar, Dhanbad, India

My students are Rachanyt HEN and Pheany PHAL, who have talked about Predicting Heart Disease using Machine Learning Algorithms. They conducted Exploratory Data Analysis (EDA), followed by the application of supervised machine learning algorithms such as K-Nearest Neighbors (KNN), Support Vector Machine (SVM), Logistic Regression, Random Forest, and Decision Tree. Then they defined the best algorithms of machine learning that work well with our dataset. The poster can be found here.

Introduction to Federated Learning [PDF]

Mathematics Association of Cambodia (MAC)
Online Seminar, Dhanbad, India

This webinar introduces Federated Learning (FL), a centralized approach that keeps data local while training models collaboratively. We explore FL workflow, client-server optimization techniques, and challenges like data heterogeneity. Using CIFAR-10 with the Flower framework, we present results, applications, and future directions. The poster can be found here.
