Gregory (Scotland Yard detective): “Is there any other point to which you would wish to draw my attention?” Holmes: “To the curious incident of the dog in the night-time.” Gregory: “The dog did nothing in the night-time.” Holmes: “That was the curious incident.” Arthur Conan Doyle “The Silver Blaze” from “The Memoirs of Sherlock Holmes” I […]
Federated Learning: How Private Is It Really?
Co-authored with Arash Nourian, Director at AWS AI Federated Learning (FL) is a widely popular structure that allows one to learn a Machine Learning (ML) model collaboratively. The classical structure of FL is that there are multiple clients each with their own local data, which they would possibly like to keep private, and there is […]
Why We Need to See Inside AI’s Black Box
This article was originally written by me for The Conversation, an online publication covering the latest research. It appeared there on May 26, 2023. For some people, the term “black box” brings to mind the recording devices in airplanes that are valuable for postmortem analyses if the unthinkable happens. For others it evokes small, minimally […]
ChatGPT Helps or Hurts our Cyber Security?
From the coverage that ChatGPT, developed by OpenAI, has been receiving since its launch in November 2022, you would be forgiven for thinking that is the only technology story around. And it deserves the spotlight. Few had expected the jaw-dropping rapid strides that this technology has made in the last few years, and it will […]
What Tech Stories to Expect in 2023
It is of course notoriously hard to make predictions in the field of technology and many wise men have been made to look silly through their failed tech predictions. Nevertheless, I sat down to look at my crystal ball to predict what stories are likely to dominate the news in 2023. The crystal ball is […]
The Caprice of Algorithms
When we design algorithms or implement them into computing systems, we rarely think about the policies that they instantiate. We rarely think beyond trite generalizations, of the countless users who may be at the receiving end of the vagaries of our algorithms. If our project becomes immensely successful, then we will count our users in […]
Is Computing Innovation Getting Harder?
The angst, or perhaps irritation, that we feel at times about the rate of innovation was captured pithily by Peter Thiel, “We wanted flying cars, instead we got 140 characters.” I am going to confine my thoughts to the world I know best, innovations in the field of computing. Many of us, inside the ivory […]
The Cost and the Rate of Innovation
Most of my colleagues and PhD students have exclaimed at some point or the other — if only I had been a researcher in an earlier time, my innovations would have been so much more impactful. This sometime happens when we look at the seemingly small increments that we make in our chosen field (Computer […]

LiteReconfig at Eurosys 2022: Cost and Content-Aware Video Object Detection for Mobile GPUs
Object detection is arguably one of central problems in computer vision. Much progress has been made over the past few years in deep learning based object detectors. Despite their impressive accuracy results on standard benchmarks, these models come at a price of their complexity and computational cost. This imposes a major barrier to deploy these […]
Distant Whispers from an Academic Engineer's World
