Master's Thesis
Heinrich Heine Universität
- Title: Enhancing Syntactic Awareness in Transformer Language Models for Hindi Dependency Parsing
- Investigated syntactic knowledge captured by transformer language models (RoBERTa, XLM-RoBERTa) for Hindi dependency parsing, a morphologically rich and low-resource language.
- Developed structure-aware model variants (Struct_Roberta_hi, Struct_XLMR) by integrating a CNN-based parser network between transformer layers, inspired by the StructFormer architecture.
- Conducted extensive error analysis including label-wise, distance-based, direction-based, sentence length-based, and LVC/Non-LVC evaluations.
- Evaluated models on downstream NLP tasks (NER, POS tagging) using the IndicXTREME benchmark.
Pretraining and Evaluation of Language Models
Heinrich Heine Universität
- Pretrained language models Roberta, StructFormer from scratch on large-scale Hindi text corpus.
- Evaluated on downstream tasks such as POS tagging, NER, sentiment analysis.
- Compared performance with baseline models like IndicBERT using standard metrics (accuracy, F1-score).
Sarcasm Detection in Nepali and Hindi Text
Heinrich Heine Universität
- Fine-tuned pretrained NLP models from Hugging Face on Hindi and Nepali text for sarcasm detection.
- Performed data collection, cleaning, and preprocessing.
- Evaluated models using accuracy, precision, recall, and F1-score; visualized results with matplotlib and seaborn.
ETL Pipeline for MongoDB to PostgreSQL
- Designed and implemented an ETL pipeline for MongoDB collections.
- Extracted, transformed, and loaded JSON data into PostgreSQL using Python.
- Developed and executed SQL script in PostgreSQL.
- Created data analysis and visualization reports using pandas, networkx and matplotlib.
Movie Data Analysis
- Analyzed a movie dataset to uncover trends and insights in film attributes.
- Imported data into PostgreSQL and executed SQL queries.
- Cleaned and preprocessed data to ensure accuracy and created visualizations.
Linear Regression Model
- Developed a Linear Regression model to predict outcomes based on various input features using Python.
- Implemented data preprocessing, cleaning and visualization.
- Evaluated model performance through metrics such as R-squared and Mean Squared Error (MSE).
Image Registration
Heinrich Heine University
- Applied image registration techniques to align unregistered brain images from a research group's dataset using Python.
- Utilized feature detectors provided by scikit-image and OpenCV to detect image features.
- Successfully registered a batch of brain images by linking transformations together.
- Employed the RANSAC method to remove outliers from the matched image features.
Studio Warehouse Associate
Shop LC GmbH
- Coordinated studio inventory operations and supervised warehouse team members.
Spectral Graph Theory and Graph Signal Processing
Heinrich Heine University
- Applied Time Evolution Fourier series techniques to analyze traffic data and identify patterns using Python.
- Used mathematical models to uncover trends and fluctuations in traffic over time.
- Generated a graph from traffic sensor data using a similarity function based on sensor location distances.
IT Officer
Stopgrab E-commerce Company
- Developed and executed social media and digital marketing strategies; managed multi-platform company profiles.
- Produced graphic and video content using Adobe Photoshop, Illustrator, and After Effects.
