Full-Waveform Inversion for Seismic Velocity Prediction

Ongoing
Research Supervisors: Naveen Gupta & Divakar Vashisth
  • Extending advisor’s ICLR 2025 latent-space-translation framework for subsurface forward/inverse problem to using Diffusion priors and flow matching
  • Working on optimal-transport-based misfit functions (Wasserstein distance, unbalanced OT) as an alternative for L2 loss to mitigate cycle-skipping on Marmousi/Overthrust benchmarks
  • Literature survey on diffusion- and flow-matching-based generative priors as regularizers for Bayesian FWI

CSD722 Project: Depth-Conditioned Video Generation using ControlNet & AnimateDiff

Jan – May 2026
Research Supervisors: Dr. Sumit Shekhar & Dr. Saurabh Shigwan (CSE Dept, SNU)
  • Extended ControlNet to text-to-video diffusion models using AnimateDiff and Motion LoRA
  • Modified model architecture to prevent training collapse where generated videos ignored depth-map conditioning; stabilized training by adding auxiliary supervision losses
  • Conducted ablation experiments on prompts, depth conditioning, and text guidance

Preprocessing Pipeline and Application of CNNs for Surface Electromyography (sEMG) Signal Classification

Jun – Dec 2025
Research Supervisor: Dr. Shilpi Modi, Sc.’E’
  • Achieved 98% accuracy by developing a ResNet, CNNs to classify surface electromyography (sEMG) stress measurements.
  • Improved classification performance from 91% to 97.98% through architecture redesign and training, showing raw sEMG inputs outperform PyEMGPipeline preprocessing.
  • Implemented AlexNet alongside ResNet experiments to further refine accuracy and generalization across sEMG datasets.
  • Selected to present this research on stress-level classification at the SUMMIT 2.0 Conference.

Time Series and Sentiment Analysis in US Financial Markets using Deep Learning

2024–2025
  • Conducted time series pattern recognition and sentiment analysis in US financial markets using 7 years of daily data across 31 financial indicators to model 2, 5, and 10-year bond yields
  • Applied PCA and Mutual Information (MI), identifying 10 key indicators explaining 95% of variance; optimised cluster timelines using rolling windows to identify dates with maximum regime separation
  • Best Silhouette Score: 0.45; ANOVA p-value: 1.21 × 10⁻¹⁵⁴, Kruskal-Wallis p-value: 1.25 × 10⁻²¹¹, confirming significant differences across clusters

Research Assistant: Investor Behavior Analysis using Deep Learning

2024–2025
Research Supervisor: Dr. Ashish Vazirani
  • Developed an unsupervised multimodal model to analyze investor emotions and decision-making patterns in Shark Tank videos
  • Combined facial expression recognition, RoBERTa-based transcript analysis, and tabular neural networks for financial characteristics, with cross-modal attention to model investor behavior
  • Fine-tuned EmotioNet for facial expression recognition and RoBERTa for transcript analysis
  • Generated time-series investment likelihood scores (–1 to 1) for each second, validated through accuracy of final decision
