Scope and Objective of the course
Neural Networks has had a long and rich history, and the reincarnated viewpoint has shifted towards "Deep Neural Networks" or "Deep Learning", primarily due to, (a) availability of the large amount of data, (b) extensive use of powerful graphics processors, (c) availability of software libraries to facilitate deep network implementations, and (d) significant involvement of industrial research labs in deep learning research.
This course on "Deep Learning" would focus on the conceptual and mathematical foundation and computational investigations of recent deep models as part of a series of laboratory experiments and projects. For instance, we will focus on newer convolutional neural networks such as VGG Net, ResNet; various sequence models including attention-based models such as transformers; and also we will touch upon graph representation learning using graph neural networks.
At the end of this course, students should be able to (0) pose real-world problems in deep learning, (1) source and prepare datasets, (2) design suitable deep network architecture, (3) prepare input-output representation (and encodings), (4) decide and design a suitable loss function for training a deep network, (5) training and deploying deep models.

Theory Materials
References to the relevent study materials are provided in the lecture slides and in some cases, these are made available separately. Duration of each lecture is 50 min, which may get extended by 10-15 min. I am thankful to my students for tolerating this aspect of my teaching. The recoded videos of live lectures are accessible to the registered students only. The slides and videos may not be in sync in some cases; that is, any slide may span over multiple lecture slots.

This will help me correct these the next time. I sincerely thank the MathCha Editor which I use extensively to draw most of the diagrams.
Lab Materials
All our labs will be based on PyTorch. See the official PyTorch Tutorials. We will also have 1 lab on basic Python and PyTorch.
Update: According to students' votes, we are fixing the lab timing to be: Wednesday 6-8 PM. Please make sure to go through the reading materials (given below) before the lab.
To run/edit the colab notebooks, please create a copy in your drive and work on that copy.
