Projects
January 2025
Implementation of RAG method to perform question answering on PDF documents. HuggingFace embeddings in addition to the Groq API were used for efficient and accurate information retrieval. Session management was done to ensure embeddings are computed once per document upload to optimize performance by avoiding redundant computations.
December 2024
Development of Web App that uses open source LLMs to answer user queries based on its own knowledge as well as any reference provided in the form of external webpages.
December 2024
"Forecasting the Future: Utilizing LSTM for Next-Word Prediction in Natural Language Processing."
October 2023
Development of a Machine Learning Model that takes user's activity data as input and predicts if the user is going to churn
September 2023
Use image processing and deep learning to alert users at the frontend that their photos might be rejected in the backend as their photo do not meet the requirements such as lighting, eyes properly visible, no spoof and properly clothed.
October 2022
Development of models that extract parameters like account number, ifsc, date, name, duration and so on and matches them with the requirements to accept or reject the account statement as a bank or income proof
March 2022
Development of Machine Learning Model that predicts similarity between 2 names trained on data collected for indian names.
July 2021
A KUKA robot was automated using a simple camera that enabled to locate, localize, identify the pose and feed the coordinates to robot in order to grisp it. Image processing techniques and deep learning methods were used recognize the object and PnP model was used to find the pose for a perfect grasp.
Work experience
