Hi, I'm Ananya Deoghare.

A
Senior machine learning engineer with 5+ years building production ranking systems that drive revenue. I enjoy turning complex business challenges into ML solutions with real impact.

About

I am a Senior Associate Algorithm Engineer at QuinStreet, where I own the end to end machine learning ranking architecture for the Personal Loans vertical, spanning CTR and conversion modeling, optimal allocation, constrained marketplace optimization, simulation, and online experimentation. Over 5+ years in AdTech and data engineering, I've focused on production ML systems where modeling decisions move revenue. Day to day, my work centers on matching consumer intent to the right offers in real time, testing ranking changes offline in a large scale simulator before any production rollout, and guarding results with experimentation and monitoring. I also help set modeling standards through design reviews.

I hold a Master's in Electrical and Computer Engineering from UCLA, where my research on equitable remote health sensing was published at SIGGRAPH 2022. Earlier, I spent two years as a Software Engineer at Accenture in India, building data solutions for the healthcare and pharma sectors, and interned in ML at VidMob.

I'm passionate about using technology to drive meaningful impact, and I thrive on transforming complex challenges into practical, human centered solutions. Outside work, I pursue Bharatnatyam, an Indian classical dance form, and cooking, both of which keep me focused and composed.

rPPG setup
Loss Function for rPPG

Shift Robust Loss Function for remote PhotoPlethysmoGraphy (rPPG)

Accomplishments
  • Tools: Python, OpenCV, Object Detection, Computer Vision, Deep learning
  • rPPG is a technique that uses slight color changes in a person’s face to find remote PPG signal and estimates heart rate from this signal using signal processing techniques.
  • We used an RGB camera to obtain face videos of volunteers and a finger pulse oximeter to obtain the ground truth PPG signal while collecting data from rPPG. These two devices are not hardware triggered, so there is a slight lag between the frames obtained from the camera and PPG signal
  • State of the art methods require the ground truth data to be exactly aligned with the signals.
  • To address this problem, we propose a novel shift robust loss function for regression that enables the network to learn from misaligned data to achieve better results than recent methods

Accomplishments
  • Tools: Stochastic processes, ito's Calculus, Brownian Motion
  • United states has seen a rapid growth in top inequality in the past forty years, i.e. the rate at which super rich are getting richer is more than the rate at which rich are getting richer, due to which the inequality between the two groups is increasing.
