Nilotpal Sinha

I am currently working as Senior Researcher at the Advanced Technology Group (ATG) in Dolby Laboratories, Bengaluru, India. Previously, I worked as a post-doctoral researcher at the Computer Vision, Imaging & Machine Intelligence Research Group (CVI2 Lab) at University of Luxembourg. Here, I focused on designing Hardware Aware Neural Architecture Search (HW-NAS) algorithms for automatically creating AI models, optimized for edge devices with low power consumption, such as Raspberry Pi and NVIDIA Jetson Nano, in space applications.

I finished my PhD in Computer Science at the National Yang Ming Chiao Tung University in 2022 under the supervision of Prof. Kuan-Wen Chen (陳冠文) as part of the COVIS Lab. during my doctoral studies. My doctoral research concentrated on developing efficient Neural Architecture Search (NAS) algorithms that could automatically generate high-performing neural network architectures for given tasks, with a particular emphasis on significantly reducing the typically high computational cost and time required for such searches.

Drone Go

  • This project deals with controlling the drone (Parrot AR Drone 2.0) to follow an object of particular color using the "Median Flow" tracker from OpenCV.
  • A PID controller is designed for controlling the movements of the drone.
  • A communication architecture was also designed to allow the drone to connect to Facebook and all the speakers present in the local network. Facebook is used to check the status of the drone and to stop the drone flight. The speakers starts an alarm when the drone is in pursuit of the object.
  • The majority of the project was written in C++ with communication to Facebook and speakers in the local network written in python.

Chess AI

  • In this project, I try to explore various ways of creating an AI agent for playing chess. Here, four different AI agents were created with the goal of beating me in the game of chess.
  • The AI agents were created using (i) pure classical method i.e. Alpha-beta algorithm, (ii) pure deep learning method i.e. reinforcement learning agent using Monte Carlo Tree Search and (iii) hybrid of classical and deep learning methods.
  • Both deep learning frameworks i.e. PyTorch and Keras with tensorflow backend was used in this project.

Journey of Reading 100 Books

A quest that started on March 2019 has reached its first milestone: “reading 100 books”. It started with a simple goal: “Do I know little bit more than what I knew yesterday?” This journey introduced me to topics that were missing from my traditional school education...

Goals

Reading 100 books (✔)

The quest of pursuing knowledge led me to my first pet project, which started on March 2019. It took me 3 years to finish this goal and was very intrumental in forming my present psyche. One of the key insights that I got during this period was that "It is just as difficult to unlearn something as it is to learn something." Read More

Try to learn something new everyday (Life long goal)

  • In the pursuit of knowledge, I came across something very fundamental about the world around us. The information content of the world is unimaginatively large and it will take a life long effort to get aquainted with it. So, it became my life long goal to increase my knowledge every single day.

  • Following this philosophy, my long term goal is to finish reading 1000 books in the next 20 years.
  • Checkout my Goodreads profile to see what I am currently reading.

Living a healthy lifestyle (Life long goal)

  • With growing age, I have grown to appreciate the benefits of exercise, and healthy eating. I have also experimented with intermittent fasting with positive results.

  • This has forced me to create a habbit of going to gym atleast 3 times a week.

Working knowledge of Quantum Computing(✔)

  • It started as a pet project during the summer break of 2020 with the goal of understanding the weirdness of the quantum mechanics and how can we leverage it for computation i.e. "Quantum Computation".

  • My aim is to use this knowledge as a base to launch into another interesting field of combining quantum computation with artificial intelligence.

  • This led me to aquire Bronze diploma and Silver diploma from QWorld. This gave me experience with Qiskit, an open-source SDK for working with quantum computers.

Working knowledge of Blockchain(✔)

This was a fun endeavor to understand the emerging technology of blockchain. I got interested in this topic after I started reading about investment. Though my primary focus was investment using blockchain, I now appreciate the technology after understanding the basics of the blockchain technology. I wonder if the technology will be useful in fields other than replacing the fiat currencies.

Habit of not making a habit (Life long goal)

Humans like to create a habit out of anything possible as it helps us to arrive at a solution to known problem much faster. The solutions might not be optimal and so we should always try to update our habits. But as we grow old, updating a single habit becomes costly in terms of both mental and physical aspects. Since we are designed to create habits, my hope is to try to create a habit of not making a habit.
