Welcome to the First Edition of DS-1.
The objective of this module is to provide a fundamental understanding of data analysis. The course proceeds in 3 parts, following the Data Science Process:
Obtain and clean the data: we will teach you how to obtain, clean, and process data from different sources such as scraped web pages, spreadsheets, APIs, and documents.
Exploratory Data Analysis: we develop your skills in pre-modeling and post-modeling exploratory data analysis and visualization. This part is all about understanding your data.
Modeling: We choose some very specific models to cover, from the perspective of teaching techniques which are generalizable to any models. Thus we will cover classification and recommendation engines. We’ll also cover similarity and PCA, as a way of understanding structure in your data and the models you ran on them.
After you finish this module, you will be ready to run the entire data science process, all on your own, from fetching (from the internet or databases) and cleaning the data, setting up pipelines, to exploratory data analysis, visualization, and modeling.
This page introduces you to the team, the basic instructions, the schedule, and various elements of our class.
Dr. Rahul Dave
Dr. Rahul Dave, former Data Science faculty at Harvard University, will be your instructor for Data Science 2. He was on the original team for Harvard’s famous Data Science course, cs109, and has taught machine learning, statistics, and AI courses, both at Harvard and at multiple conferences and workshops. You can read more about him here.
The teaching assistants for the duration of this course are:
- Anusha is working as a Research and Teaching fellow with Univ.ai, she has previously worked with Robert Bosch as a software engineer in the automotive domain.
- She is an incoming student at TU Delft.
- She is a big believer in sustainability and has been working on applications of AI in sustainable energy for the last 3 years.
- Arya is currently a data analyst at Schneider Electric and a Teaching Assistant at Univ.AI.
- She is passionate about image processing and is currently researching the application of computer vision in the detection of deep fake videos.
We have very carefully designed the coursework to give you, the student, a wholesome learning experience. Each week shall include:
- 2 Sessions
- 1 Lab
- Office hours
Session - What to expect
Before the session begins, students are expected to complete a pre-class reading assignment and attempt a quiz based on the same.
A session will have the following pedagogy layout which will be repeated a few times:
- Approx. 10-15 minutes of live online instruction followed by a quiz
- Some sessions will have hands-on coding exercises or group activities
- Sessions will help students develop the intuition for the core concepts, provide the necessary mathematical background, and provide guidance on technical details.
- Sessions will be accompanied by relevant examples to clarify key concepts and techniques.
After the session, students are expected to complete a short post-class quiz based on the principal concepts covered in class and optional post-class reading will be provided.
Lab - What to expect
A lab is a TA driven 1.5 hour session that is divided into 3 major parts.
- Each lab begins by solving parts of a complete problem. This problem is designed to help you with your homework and further elucidate concepts you learned in lecture.
- After discussing exercises, we will have a semi-formal Q/A session. The first part of this session is limited to homework questions, but the second part is more free-for-all, where you can ask any doubts that lingered over from lecture.
Welcome Session - Preparing for this class
There will be a Welcome Session scheduled on
25 January 2021 at
7:00 PM IST for all registered students. Please check your mail for more information.
NOTE: Below timings are in IST
- Tuesday Series: 9:00 PM - 11:00 PM
- Friday Series: 9:00 PM - 11:00 PM
- Saturday Series: 7:30 PM - 8:30 PM
- Mondays: 9:00 PM - 10:00 PM
- Wednesdays: 9:00 PM - 10:00 PM(Professor office hours)
You are expected to have programming experience and basic machine learning concepts such as model fitting, test-validation, regularization, etc.
- Programming Experience:
- Pandas - Specific topics: Introducing Pandas Objects Data, Indexing and Selection
- NumPy - Specific topics: Understanding Data Types in Python, The Basics of NumPy Arrays, Computation on Arrays: Broadcasting, Comparisons, Masks, and Boolean Logic
- Matplotlib - Specific topics: Simple Line Plots, Simple Scatter Plots, Visualizing Errors, Density and Contour Plots, Histograms, Binnings, and Density
- Sklearn API
- Machine Learning Experience:
- Loss functions
- Overfitting and regularization
- Regression and classification
You can also use, MLPrep and PyPrep provided by Univ.AI to learn the topics mentioned above.
In addition to this, you can use the book - Introduction to Statistical Learning to refresh the basic mathematical concepts and Python Data Science Handbook to refresh machine learning concepts.
Diversity & Inclusion
We actively seek and welcome people of diverse identities, from across the spectrum of disciplines and methods since Artificial Intelligence (AI) increasingly mediates our social, cultural, economic, and political interactions .
We believe in creating and maintaining an inclusive learning environment where all members feel safe, respected, and capable of producing their best work.
We commit to an experience for all participants that is free from – Harassment, bullying, and discrimination which includes but is not limited to:
- Offensive comments related to age, race, religion, creed, color, gender (including transgender/gender identity/gender expression), sexual orientation, medical condition, physical or intellectual disability, pregnancy, or medical conditions, national origin or ancestry.
- Intimidation, personal attacks, harassment, unnecessary disruption of talks during any of the learning activities.

Logistics: What do you need to begin?
We assume you have a Univ.AI account, created when you signed up at courses.univ.ai. If not, email email@example.com.
- You MUST connect your courses.univ.ai account to Github. Here (install instructions) is how to do it!
- You MUST log on to discourse.univ.ai forum software. Here (install instructions) is how to do it.
- Before the first class, you will want to install Anaconda Python and play with Python a little bit. You will learn a bit about Jupyter notebooks, and a bit about Python coding. We’ll talk about Anaconda in class.
Education software we use
- Our lectures and labs are carried out via Zoom (install instructions).
- Quizzes & exercises will be conducted on the digital learning platform Ed.
- All exercises and homeworks in this course will be done in jupyter notebooks. This link will help you setup jupyter lab and get you acquianted with jupyter notebooks.
- We have an innovative platform for our courses. Here is some usage information for it. We will talk about the platform in class.
- The Slides will be available on Univ.AI Platform.
- For forum discussion we will be using Discourse.
- And for homework submissions and lab work we will be using github.
