🎉 Our paper accepted at ICLR 2026! We study the backbone of applications like search, recommendation, & RAG: “Nearest Neighbor Search.” But instead of optimizing only relevance, we ask 👉 Can we balance relevance & diversity in a principled way? Paper: arxiv.org/abs/2602.08742

Theory → Practice 📈 • Provable efficient algorithms • Works with standard ANN systems • Strong empirical gains in diversity while maintaining relevance in several real-world datasets Joint work with @BarmanSiddharth, @shivi98g & @KShiragur. See you at ICLR 2026 in Rio 🇧🇷

Absolutely terrible policy instituted at @iiscbangalore. Mandating attendance hours for faculty and staff is the worst possible way to get them to spend more time there. I don’t know where IISc administrators get their ideas from, but they need 21st century play books. hindustantimes.com/india-news/stu…

The paper titled "Improved Approximation Algorithms for Three-Dimensional Bin Packing" authored by Debajyoti Kar, Arindam Khan, and Malin Rau, has been accepted for publication at the 52nd EATCS International Colloquium on Automata, Languages and Programming (ICALP), 2025.

Dear young brothers and sisters from India. Don’t listen to people telling you universities don’t matter, unless you are super privileged and have a broad exposure or you are pretty sure you can’t make it to any of the top one. Preparing for university admissions connects you to the most ambitious and vibrant social group among Indian students. This is one of the most fun experiences if it is aligned with your interests (and you can make anything aligned with your interests). Top Indian universities connect you to the world, expose you to global ideas. These are a gateway to mainstream.
