Predicting Glass Properties using Machine Learning

This project focuses on predicting the properties of glass using various machine learning techniques. The goal is to develop predictive models for the glass transition temperature (Tg) based on a dataset of glass compositions. This is achieved through a series of Python scripts organized in a structured directory.

Overview

The project utilizes a dataset of approximately 29,000 glass compositions from the SciGlass database to predict the glass transition temperature (Tg) using machine learning algorithms such as Random Forest, Gradient Boosting, and Support Vector Regression. The best-performing model was optimized and evaluated using various metrics, demonstrating the potential of machine learning in materials science.
