Multimodal Sentiment Analysis using Deep Learning

(Feb 2024 – Feb 2025)
  • Developed sarcasm detection models on context-free text utilizing LSTM and Bi-LSTM architectures, benchmarking against LLMs (GPT-4o, GPT-3.5) and logistic regression
  • Fine-tuned RoBERTa for sarcasm detection (context-free/with context), achieving F1 score of 0.79 on Reddit data; improved performance with stop-word handling, attention mechanisms, and emoji-to-text preprocessing
  • Extended research to multimodal sarcasm detection by combining video, audio, and contextual text with LSTM-based binary classification, achieving an F1 score of 0.808 on Mustard dataset
