Proactive Failure

Prediction (In

collaboration with

McKinsey)

While being on-site (US), Delivered $12M of savings to Engine Business Unit and avoided over 4000 days of downtime for customers by using a machine learning model to identify high-risk engines in the field and guiding the Sales team in running a targeted campaign

Developed Semi Supervised Algorithm to increase training data for better predictions

Generalized the model for reliable predictions by analyzing co-variance shift in predictors Attrition Risk

Prediction

Done predictive analytics on HR data to identify high-risk population for retention strategies

Processed the data from different sources and build machine learning classification models

Interpreted ML models by SHAP & Surrogate Decision trees to derive strategic business insights Computer

Vision

Built an end to end object detection algorithm using advanced deep learning algorithms like YOLOv3 and SSD to recognize persons not wearing helmets in a manufacturing plant

Optimized the mean Average Precision from .4 to .65 by implementing relevant augmentation techniques to increase the training data and by improving image annotation approach Class Imbalanced

Classification

Problem

Worked on highly imbalanced classification problem and built a clustering algorithm on the majority class and by combining each sub-group of majority class with bagged minority class to generate balanced training data and maintain data diversity

Built automatic claims classification algorithm to speed up the process of getting labelled samples

Implemented a keyword search logic along with proximity of negation words for classification Text Analytics Currently working on developing chatbot for various IT applications (Remedy/company policies)

Exploring more on Seq2Seq models for contextual relevance and other Q&A type algorithms Paper publications/ Abstract

Multivariate Time

Series Forecasting

Paper on “Macroeconomic Statistical Forecasting for Engine Demand” at URoS 2018, Netherlands.

The paper explains multivariate forecasting using statistical pre-processing of macro-economic indicators and identification of significant lags of predictors

Developed a framework to measure three months out statistical forecast of engine demand Achievements

Topper in Mathematics and Applied Mathematics courses in undergraduate studies resulting in internship at IIT Bombay

(Recommended by Prof. S.K Gupta, Disguised retired Professor of IIT KANPUR)

Cleared Indian Statistical Institute entrance exam (2015) in M.Tech QROR and was among the top 16 students who cleared this highly competitive exam for masters

Winner, Alok Bhatia Mathematical Regional Olympiad from 2002 to 2005

Conducted Campus hiring for interns in Advanced Analytics Team, Cummins from ISI Kolkata/Bangalore

Lead and grow the Data Science & Machine Learning team with interns to identify, implement, and present results of research on novel ways how machine learning approaches can improve decisions and analytics solutions

Transformed the true value of data as perceived by the organization by proving the value of data-based decision making

Improved models built by other analytics teams and further trained them to effectively work on data science problems

Got Recognized as the employee of the year consecutively for two years among all advanced analytics teams globally Technical Skills

Programming Languages – Python, C, SQL, LaTeX

Statistical Software – R, Minitab, MATLAB
