+## Course Objectives:
+This course aims at introducing the students to advanced topics in machine learning (ML). 
+The main focus will be on Generative machine learning and Trustworthy AI.
+The lectures will focus on mathematical principles, and there will be coding based assignments/project for implementation. 
+
+## Pre-requisites:
+- Basic course on machine learning (EE698V, EE603A or equivalent). [Lecture videos](https://www.youtube.com/playlist?list=PLbtAaXHMto-sQHH1qrYn8_D9Fze_D1KhE)
+- Basics of Programming (ESc101, EE698K or equivalent)
+
+The course will need a strong background in linear algebra and probability theory.
+
+## Topics:
+
+- Basics
+  - Probability theory 
+  - Neural Networks 
+- Generative Machine Learning
+	- Random sampling (Monte Carlo methods)
+	- Variational Inference
+	- Generative Adversarial Networks
+	- Normalizing Flows
+  - Diffusion Models
+- Trustworthy AI
+  - Uncertainty Estimation
+  - Model calibration
+  - Human in the loop learning (mislabeling detection, active learning)
+- Optional
+  - Explainable AI (LIME, SHAP, Grad-CAM)
+  - Data efficient machine learning (small data, model adaptation, semi-supervised learning)
+
+## Grading Scheme
+- Quizzes/Assignments - 30% 
+- Mid-semester Exam – 30%
+- End-semester - 40% 
+
+Minimum attendance of 80% is needed to pass the course.
+
+### Plagiarism Penalty:<br>
+As heavy as possible. Zero-tolerance policy.
+
+## References:
+  This course will take excerpts from some standard books on machine
+  learning and signal processing. But it will largely be based on
+  articles and research papers in ML and SP conferences (e.g.,
+  NeurIPS, ICML, ICLR, Interspeech, ICASSP, etc.) and journals (e.g., IEEE
+  TASLP, JMLR, IEEE PAMI, etc.).
