This Week's Reads

Read one, tweet about it — that's your post for the day.

1
How Netflix, Spotify & Instagram Actually Use Python
Netflix uses NumPy/SciPy for recommendation math, Spotify uses Pandas and Luigi for Discover Weekly, Instagram handles millions of uploads per minute — the libraries from Days 2-4 as real tools, not exercises.
2
Visualize Like a Pro: EDA on Roller Coaster Data with Seaborn & Matplotlib
Full EDA on a real roller coaster dataset — histograms, box plots, count plots, categorical filtering. The exact Day 4-5 toolkit with clean visuals showing how the right chart type changes what you see.
3
Airbnb: Using ML to Predict the Value of a Home Listing
A real production story from Airbnb's engineering team — feature engineering on location, property type, amenities, handling missing values, and the full pipeline from prototype to production.
4
Logistic Regression in Real Life: Building a Daily Productivity Classifier
Predict whether a day will be productive using hours slept, meetings, and exercise. Why linear regression fails for binary outcomes, how to frame classification, and interpreting coefficients in plain English.
5
Best Methods for Feature Engineering Categorical Variables
One-hot, label, ordinal, frequency, target, and embedding encoding — each explained with a real use case and a clear downside. Multiple practitioner perspectives instead of a single textbook answer.

How It Works

Four rules. That's it.

1

Post on X

At least 3 times a week. Don't know what to post? Start with This Week's Reads — pick any article, read it, and tweet your takeaway. That alone is a solid post. Beyond that, anything you learned during SA works: a concept, a bug, a breakthrough, a hot take. Tag @cnaiitg with #SummerAnalytics2026 and #BuildInPublic.

2

Follow the Starter List

These are the people shaping AI right now. Following them fills your timeline with signal, makes your profile look serious to recruiters and peers, and gives you better content to engage with and quote-tweet.

3

Write it yourself

The tweet templates below are great for formatting — use them to get started quickly. But your own words always hit harder. No AI-generated slop. Say something real.

4

Winners every Sunday

Consistency — how often you showed up. Quality — original thinking, not copy-paste. Engagement — reach, replies, and conversations your post started. Prizes worth ₹10,000 split among the winners of the week.
