Module 7: Advanced ML Topics & Ethical Considerations (Weeks 13)

Advanced machine learning techniques focus on handling complex data types, primarily sequential data commonly found in text, speech, time series, and videos. The chapter explores Recurrent Neural Networks (RNNs), including Long Short-Term Memory (LSTM) networks and Gated Recurrent Units (GRUs), addressing their applications in natural language processing, time series forecasting, and association rule mining through the Apriori algorithm. It also examines recommender systems and compares content-based and collaborative filtering approaches.
