Shalini Joseph presented on "Python and Machine Learning". Python is an easy to learn, open source, high-level programming language developed in 1989. It is useful for a variety of applications including web development, data analysis, machine learning, and artificial intelligence. Machine learning uses algorithms to learn from data and make predictions. The presentation covered types of machine learning like linear regression, multiple linear regression, and logistic regression. As a project, linear and multiple linear regression were used to predict house prices based on features like size, location, and age. The internship provided hands-on experience with machine learning algorithms in Python.
