About Me

I am a final year undergraduate student pursuing my Bachelors of Technology in Information Technology from Veermata Jijabai Technological Institute, India. Ever since my first year in college, I have been keenly interested in the field of Machine learning. Our increased ability at cross-language interaction by building efficient lexical semantic analyzers and multi-variety models is what draws me to this field immensely. To pursue my research interests, I tried my hands on interesting ML problem statements in the Centre of Excellence, the research incubator of VJTI, accoladed as the Best Incubator of India as of 2020. I wish to further explore opportunities in this domain that would efficiently change the way people communicate.

In addition to this, I have a keen interest in music. I am a music aficionado at heart and the days I seem to hit the wrong note, my guitar helps me harmonize. Being well versed with 4 musical instruments, my days aren’t complete without an element of music. I also greatly enjoy listening to podcasts centred around Artificial Intelligence and experts' opinions on such subjects.

Community Detection and Impact of Bots on Sentiment Polarity of Twitter Networks

This paper focuses on plotting a network of Twitter users, based on a particular hashtag, and detecting the communities in it, followed by detecting and locating the bots in these communities. In addition to this, sentiment analysis is conducted on normal users’ tweets as well as the bots in these communities. This paper also aims to identify the overall sentiment of the communities, and thus provide promising conclusions relating to bot behavior in the overall network.

AI Based Nose for Trace of Churn in Assessment of Captive Customers

In this research paper, we present a comparative study of the most popular machine learning classifiers used to solve the problem of churning customers in the telecommunications sector. In the first phase of our test, all models were implemented and tested using statistical evaluative measures on the popular telecom database. In the second phase, the performance improved by boosting was evaluated.

Twitter Bot Detection and their Influence in Hashtag Manipulation

This research has used varied approaches for the detection of bots; a supervised machine learning approach which makes use of a unique feature called the bot score to determine the bot probability of a user. Secondly, using an unsupervised machine learning approach, users were divided into various clusters based on their activity. Furthermore, to assess the influence of users in hashtag manipulation, this research analyzed various categories of users in a hashtag and made promising conclusions.

Projects

Bearing Fault Analysis

Estimated the remaining useful life of a bearing using Machine Learning. Achieved better prognostic performance with 98.2% accuracy as compared to SOTA techniques such as Kalman filter.

Cleangenix

Devised a solution to improve city sanitation under Solid Waste Management Department using Neo4J and PostGreSQL. Developed an algorithm to identify trash from geotagged images using a Mask R-CNN model.

Startup Quest

Created a social media bot which indexes 2000+ potential startup ideas in a database and a CRM dashboard to display it. Developed a news feed scraper to trace activities of the projects by web scraping data using Beautiful Soup.

Unsupervised Speech Summarization

Performed text summarization by clustering sentence embeddings trained to embed paraphrases together using K-Means. Improved the accuracy by using a Skip-Thoughts (GRU-RNN) model to preserve sequence of words in a sentence.

GeoTracking of Waste

Devised a platform for BMC, the governing civic body, to view the real time location of garbage trucks and the amount of waste collected.Created a dashboard to view daily statistics and reports in order to formulate measures to optimize waste management
