馃搨 Projects

CNN vs. ViT Robustness Under Distribution Shift

Academic computer vision research project comparing ResNet-50 and ViT-S/16 under distribution shift.

  • Trained and evaluated ResNet-50 and ViT-S/16 under controlled conditions
  • Evaluated robustness using ImageNet-C, ImageNet-A, and ImageNet-R
  • Analysed corruption families including noise, blur, weather, and digital corruptions
  • Studied the effects of AugMix and training duration
  • Compared absolute and relative robustness metrics

Topics: Computer Vision 路 Vision Transformers 路 ResNet 路 Robustness 路 Distribution Shift 路 Deep Learning

Spoken Language Identification for 22 Indian Languages

Academic speech-classification project for identifying spoken languages from audio recordings.

  • Fine-tuned W2V-BERT for 22-class spoken language identification
  • Built the training pipeline with PyTorch, torchaudio, and Hugging Face Transformers
  • Applied speed perturbation, pitch shifting, and Gaussian-noise augmentation
  • Analysed model behaviour using confusion matrices and t-SNE visualisations
  • Best reported validation accuracy: 36.45%

Topics: Deep Learning 路 Audio Classification 路 W2V-BERT 路 PyTorch 路 Hugging Face 路 Speech Processing

Analysis of Open-Ended Survey Responses

German-language NLP project analysing open-ended political survey responses.

  • Compared BERT, lexicon-based sentiment analysis, and a rule-based ensemble
  • Used Python, pandas, Hugging Face Transformers, NLTK, and scikit-learn
  • Evaluated the methods against manually annotated responses
  • Combined approach achieved 58.0% accuracy and a Macro-F1 score of 0.537
  • Created visualisations for sentiment results, term frequencies, and model comparison

Topics: NLP 路 BERT 路 Sentiment Analysis 路 Python 路 Machine Learning 路 Data Analysis

Django Fame-Based Social Network

Portfolio documentation for an academic Django software-engineering project.

  • Extended an existing Django social-network application
  • Worked on reputation and profile-update functionality
  • Implemented expertise-community and timeline features
  • Worked with user-similarity logic and relational data
  • Used Django REST Framework and backend/API functionality

Topics: Python 路 Django 路 REST APIs 路 Backend Development 路 Databases 路 Software Engineering
